audio-tech

[lone flame]

It is a variable that someone can control. It's just really hard and most just fail

And this Microdetails idk everyone has a different definition of what it means. And "quiet sound pickup"? There is no noise gate or so that only plays sound when it reaches a specific DB level

My man 💪

[elder thistle]

aside from it not being a variable someone can control, it is a function of dynamics. specifically the lack of them at the tail end and downwards

the quietest details and fluctuations in a sound are brought to a louder perceived volume level alongside the rest of the sound

when that happens, it more easily fights masking

[green marsh]

microdetails is dynamic range and macrodetails is slam

[elder thistle]

however, non-stage instrument separation will destroy these details first

this is why the behavior of each game's sound engine presents a different workload, pointing to a different headphone

[green marsh]

i mean it doesnt matter regardless

[elder thistle]

it's also a big, real component of why the m50x gets a lot of continued use by music producers as a tool

it's completely separate from frequency response too. happens on bright headphones, dark headphones, super screwed up comb-filtery ones, ones with holes in the upper mids or treble

excellent measurement consistency, horrible consistency

I believe you yakucho when you say you hear techs change or go away when you eq

that will always be granted through the concept of "no invalid experiences"

but you either listen/judge differently in a way that misses or can't categorize these things, have invalidated your experiences yourself, or have ears and a brain that are fundamentally different from almost everyone else in a way not yet discovered by human science

not that science has discovered much at all on this front

[livid ruin]

sign for elon mushkskssks brain chips maybe that will leap into bigger and better audio 📈 💿 📞

what could go wong

[elder thistle]

melon husk

[tawdry gale]

Musk melon

[noble axle]

would the meze 105 aer be worth the $400, ive been using a pair of sennheiser hd6xx's and theyve just gotten kinda dull to me

[lone flame]

dynamic rage on a transducer is insane. i mean. it just plays what the source gives it

so its limited by source. and slam? Ez to EQ

[lone flame]

nah prob because of the name and general status like Beyerdynamic.
And M50x is kinda cheap

[lone flame]

seperation is part of FR.
it is easy to explain.
If the FR is far away from your HRTF. Sound seperation is kinda fcked,
If its near. It gets better
and the FR will looks REALLY REALLY weird

[lone flame]

when i EQ after "my way" it always leads to the exact same results

i just EQ out EVERY Peak and dip.
i try to make every frequency the same volume and the result is always the same

i mostly do that through 2-3 days due to hearing diff on each day
so to make an average etc

and it just works and sounds awesome

yours?

[lean grove]

Hard to say since we're not you. 105's will have better bass extension and maybe a bit wider soundstage.

[elder thistle]

explain how headphones with high seating variance don't cause a change in techs

[elder thistle]

I eq headphones together to better hear their differences

every peak and dip

[zenith pawn]

the FR isn't everything you hear

Well, maybe it is for some people

and who says your HRTF is a simple parametric EQ

[robust shoal]

Hey everyone i need to replace the pnp Transistor (the b618a) but i can not find any is there a replacement or compatibl one its for my Pioneer SA-606 amp
any advise?

[pallid wind]

So I've been thinking after a few suggestions here and I'm returning my DT770 Pro X and getting the FT1.

[lone flame]

Because the tech of the driver is fixed on someone's head. There is of position variance etc. But that's just a change in FR.

[lone flame]

Welcome to the FT1 crew

Luckly FT1 are aviable atm lol.

They where ALOT out of stock in the past

[pallid wind]

Looking at ordering from amazon

Do people recommend replacing the cable?

[warm scarab]

not a bad call

[lone flame]

For me it's way to stiff

[warm scarab]

comfort matter

[lone flame]

I got an simple Openheart cable from aliexpress

[pallid wind]

Do they change the audio quality by any chance?

[lone flame]

Nope

Maybe on measurements by 0.2 d or so

But that's due to impedance lol

So absolutly NOT audible

[pallid wind]

wow 30 bucks for cable?

[lone flame]

Yeah xD

That's normal pricing

I have 2 cables that cost 120€ lmao

Each

[warm scarab]

make yours if you want

30$ is also completely stupid imo

cables cost like 5$ to produce

and the "high quality" ™ cables cost like 20$ in materials maybe

its a complete scam to pay for cables

[lone flame]

Many cables are hand made

[green marsh]

shipping, labor etc

[warm scarab]

you can buy wires locally

shipping is a cope

you can also buy 3.5 in most areas locally

[lone flame]

And mostly the cables we talk about has a more complicated manufacturing style

Like braiding etc

[green marsh]

guess what they still had to be shipped in from somewhere

[warm scarab]

even if not locally you can buy parts from inland

[warm scarab]

yeah except they pay 50$ in shipping for 5000 pieces

so instead of paying 51$ you pay 1.5$

I can literally go on the internet

[green marsh]

and stores gotta make a profit too

[warm scarab]

pay 3$ for shipping and buy 30 cables worth of components

[warm scarab]

yeah the 0.50$ is their profit

its a 1$ bit bro

150% upmark is sufficient

[green marsh]

i mean sure if its a mass produced cable it shouldnt cost more than 10 to 20 dollars

[warm scarab]

who said cable

I said 3.5 and wire

[green marsh]

.

[lone flame]

Most cables are made by making a 10km long cable. Cut of 2 ends. Put a connector on it done

[warm scarab]

you can make 10 mass produced cable's worth of cables for 20$ of your money

[green marsh]

and how many labor hours

time is money

[warm scarab]

like

[lone flame]

Headphones cables are specifically designed to look good and feel good etc

[warm scarab]

i could do it in what

1 hour if i take it slow

stop projecting your skill issues

[warm scarab]

they literally all use the same components

[green marsh]

and if someone doesnt have the skills yetit would probably take multiple tries

[lone flame]

A 5090 is 2k+....

[warm scarab]

they dont put magic dust in their stuff to make it look good

they buy a sleeve

a cable

and 2 connectors, solder them

you can buy the same exact stuff

[warm scarab]

better start learning then

shit goalpost

did I say that anyone can make 10 cables in 2 minutes

no I said you can make 10 ready cables for 20$ worth of components

[lone flame]

30 buck are worth to not learn that

[warm scarab]

if you are bad you are bad I cant help you with that

[green marsh]

im sure i could but i just use stock cables lol

[warm scarab]

because skill issue

[green marsh]

custom cables are for losers

frfr

[lone flame]

[warm scarab]

posting that on anthony's discord you are gone

[lone flame]

240€ for 2 custom cables

[warm scarab]

you got scammed

[lone flame]

They are handmade 😊

[warm scarab]

you paid 240 for 10 minutes of labor

[green marsh]

oh no

[lone flame]

And?

[warm scarab]

ur bad

[green marsh]

but but muh occ litz

[warm scarab]

man I should sell custom cables

[green marsh]

[warm scarab]

there are so many dumbass audiophiles who would buy it

this is crazy

imagine this you buy 10$ worth of components with 5$ shipping from ali

sell it to 10 dumbasses on discord for 100$ a pop

[green marsh]

have you seen nightjars cables 💀

[warm scarab]

no wonder anthony started a business

[warm scarab]

no

have you seen audiophile dog cables

[green marsh]

thats 5500

[warm scarab]

he gave himself lacerations to convince people they are magical and he took them from a temple defended by a magic beast

and no im not lying

[lone flame]

That's a scam

[pallid wind]

wtf? do they use real gold or something

[green marsh]

aint that the guy who fucked up a k1000

[warm scarab]

he worships k1k yeah

[green marsh]

and sells crystals

[warm scarab]

idk if he fucked one up tho

[warm scarab]

yes

he gave himself lacerations for the crystals

[green marsh]

yeah he cut holes in the grill of a k1000 and cut the cable to make it like 6 inches

[warm scarab]

lmao

[lone flame]

Loser

Well. I think like up to 200 bucks It's fair for custom cables

[green marsh]

nah but if you have shitty headphones itll "bottleneck the cable"

[warm scarab]

bro hit me up

[pallid wind]

lmao

[warm scarab]

ill make you whatever cable you want for half of the price

lmao

[pallid wind]

okay im gonna order these FT1. Seen a lot of good reviews for them.

[green marsh]

read this headfi review https://www.head-fi.org/showcase/nightjar-sovereign-symphony-iem-cable.27271/reviews

[lone flame]

I want an antimatter cable for 50 bucks

Ok om gone

[warm scarab]

okay sure

just get a photon microscope to see the antimatter

its there i assure you

[pallid wind]

Also, do the FT1 need amps? This like my first time getting a pro headphones

[warm scarab]

bro holy shit

[warm scarab]

its good

probably

not that insensitive

[green marsh]

While I’m no tech expert, what I take away from this is the Sovereign is really a pure copper cable. Using a small amount of silver on the grounding side seems to bring a touch of silver’s performance and tuning flavor, (counteracting copper’s final flaws) but this is a flagship copper cable at heart. Super cool. When looking deeper I start to see the SS’s presence growling into focus: it’s waaaay more wire. Going from 22AWG to 19AWG, plus doubling the wire count (from 2 to 4) means the SS is more than meets the eye, and uses far more material to build. The resistance also drops to a very impressive nearly nothing 0.04 ohms. This is not just sticking two Sovereigns together and calling it a day, it seems the foundation of the Sovereign has been amped up, rethought, ‘suped up with the SS, offering more than just extra wire. I love this, not resting on laurels, see how far things can get pushed.

i dont get how people actually believe this shit

[warm scarab]

its called letting boomers be a part of your hobby

this is why the 3d printing community is so good

because it has no boomers in it resulting in zero ambiguity

tech didnt exist in their time

[pallid wind]

Just order the FT1! Should be here tomorrow.

[fleet turret]

looking to upgrade my audio game, currently have a logi pro x wired, was thinking about getting the truthear pure IEM’s?

im mainly wanting just good audio quality (music etc) but also do some gaming.

any recommendations are appreciated

budget is lets say around 200, this would be for headphones and dac if required but the IEM’s are looking appealing at their price point

[tawdry gale]

For ur first iem, I would recommend Tanchjim Bunny Dsp, as u don't know what ur preferences are

And it is better than ur logi x wired

Plus u don't need to buy a dac/amp for it as the dsp cable it comes with is a good dac/amp

[fleet turret]

How is getting those going to determine my preferences?

[tawdry gale]

U can eq the bunny to ur preferences

Via the tanchjim app

When using the dsp cable

[green marsh]

if you wanted to consider headphones id recommend either hd560s or ft1

[fleet turret]

Can’t I just get the others and eq them?

[tawdry gale]

If u don't need isolation, I would also recommend hd6xx

[tawdry gale]

Bunny is cheap, and it's tuned very linearly which makes it easy to eq

If u figure out ur preferences it's easier to buy more expensive iems that u won't need to eq

[warm scarab]

@lean grove

jvc

[quiet ice]

jvc indeed

[unique wind]

the local legend returns

[quiet ice]

💪 💪

lmaoo

[elder thistle]

this doesnt check out

you could eq all the peaks and dips away in 1 position

then you could change the position and there are new peaks and dips with the same eq

if eliminating all peaks and dips changes techs like you said, there is no possibility left for the techs to be unchanged

[elder thistle]

do not simply get the 560s or ft1

what kind of music are you listening to, and what do you want to hear in this music?

[lone flame]

Some headphone designs are more consistent with that

And some peaks and dips are so small that it's not really audible

[lone flame]

Do you have an external mic?

[lone flame]

Majority of people would recommend FT1 as closed back by far

[fleet turret]

Yea

[lone flame]

Way over DT 770 Pro, way over M50x, way over these Mackie things

[lone flame]

U want closed back, open back or in ear?

[fleet turret]

I don’t have a specific answer, I listen to everything

[fleet turret]

I don’t mind. I was looking at the Truthear Pure and a bunch on forums said it was really good for the price

[lone flame]

Ye it is. But open back, closed back and IEMs do sound different out of the box

And each one has pros and contras

[lone flame]

U want Bass? Like a ton?

[fleet turret]

Not a ton

Balance

[lone flame]

And do you want the headphone to be isolated from the sounds around you?

Or don't you mind

[lone flame]

Aaaand.
Are u from the USA?

[fleet turret]

Don’t mind

[fleet turret]

No, i’ll most likely order from us amazon

[elder thistle]

many headphones still have large dips and large seating variance. the question is with those

[elder thistle]

there are many issues with the ft1 and 560s that are widely reported by non-reviewers

one person today has already succumbed to this gap between objectivists and casual listeners today

you don't want to be second

[lone flame]

I'm both

That's why I don't really put in my personal preference, more likely what the majority of people say

And majority says... FT1 👌

[elder thistle]

headphones and picking an optimized headphone for your use case and preferences requires considering many, many things. it's more complex than buying a house or building a computer, and by necessity needs boiled down

but we need to know things like genres of music because it's arguably the most efficient way to gauge what mix and amounts of attributes a headphone should probably have

but we can sti) try to start from zero

[lone flame]

Like he said. He wants just good sound and has no real fixed music style

[elder thistle]

unfortunately there is no definition or standard for good sound

[lone flame]

There isn't. But Graphs are a good baseline. And the 5128 is good bcs of its acoustic impedance

[elder thistle]

how mushed together or surgically separated you want overlapping sounds to be? this will still be hugely controlled by the type of music played on them. less sounds at once = more details and clearly separated / defined identity of each sound.

high detail / separated sounds is helpful for competitive gaming

its just that many people find too much detail no longer immersive

[lone flame]

That's mix diff. Not headphone diff

[elder thistle]

the reviewerbase and people finally getting an expensive headphone are as representative of the global average opinion as the amazon review thread for the dt990 is

which is to say about 50/50 despite nearly a 5 star rating

headphones apply their non-stage instrument separation to every mix, optimized mix or not

[lone flame]

For me majority is only from people that actually knows something about headphones

[elder thistle]

and the headphones take that hit proportionally to other headphones

[lone flame]

Not like someone who came from a razer headset to a better rheadphome

Someone with experience

The DT990 has a widely big status. Especially under the non audio people.

FiiO on the other side is just non existent to non audio people

2 different worlds

Like in Germany. Everyone knows Beyerdynamic. But Noone knows FiiO

[elder thistle]

people were made to know fiio

obviously the objectivist crowd has taken well to the ft1. that was almost predetermined by a 5128

subjectivist reviewers and most people, though way quieter, have not had the same reaction

I've encountered lots of small reviewers and newcomers who did not like the ft1 for a trend of reasons

I've seen them revert back to dt770's, cloud alphas, m50x's, hd280 pro's, k371's etc

it sees frequent rejection for mixing, comp fps, and genres of music with real life instruments

and that was almost predetermined by being a headphone that exists amongst competitors

[lone flame]

Funnily that like every legit knows reviewer says that the FT1 are good

[lone flame]

FPS is hrtf l. So FR. Whoever mixes with a closed back is just dumb loool.
And what has instruments to do with it?

I don't see any reviewer that you mentioned. Erc

Only find FT1 likes mostly

[tawdry gale]

K371 is still ok

[lone flame]

Pad diff

[tawdry gale]

I agree

[elder thistle]

I mix on closed backs

I mix on them more easily than my adam t5v's and hd600

the apparent popularity of the ft1 is blown out and super hyped if you just do a google search, yes

was helping this guy they other day

https://www.youtube.com/watch?v=B4s2x21ltQ8&t=1026

excellent review actually, way more comprehensive than the others I've seen

[zenith pawn]

is burn in real or is that just your ears getting used to the headphone

[elder thistle]

ears, probably

it's good that people sink into the frequency response over time, but that's shorthand for saying the treble and ~4k area are commonly messed up

and it could be true of almost any headphone

[warm scarab]

ears

for speakers its kinda real

for headphones and iems nah

[robust shoal]

any idea?

[lone flame]

They talk about Burn in...
That's not a quality review

Burn in "ears" would be more likely "get used to the sound"

Also look in the comment. ALOOT of people like them

[elder thistle]

a lot of them are noting that they're not native to the channel

the nature of hype products is for non-knowledgeable buyers who are happy with the product to go on a crusade

because that's the way it was first presented to them

example: the dt990 crusade

https://www.youtube.com/watch?v=2c-Z4iY1l8M

people are also prone to attacking when something they like has something negative said about it

the best way to gather an idea of how often someone likes or dislikes a headphone is beating them to the punch and prompting them to say their thoughts

if they just say something naturally, it leans positive

[elder thistle]

as for this review, sharing a product experience doesn't require someone to be an expert

product experiences are ultimately what a person watching a review is hoping to duplicate

that's why the dms video here contains far less review information, and lacks relevancy

[glad creek]

Dt headphones are great if you want something solid, long-lasting and bulky for jobs like football commentators or radio or whatever

But the sound really isn't that great and oh god the comfort is inexistent (well this is personal)

I've owned multiples headphones (multiples at the same time) over the last decade

Now I just use an HD 600, because it's cheap, lightweight, ultra comfortable (I use it 10h/day everyday) and the sound is OK

Best sound I've heard was my stax SR507, probably due to the super deep bass extension with absolutely no distorsion across the whole spectrum and super fast impulse response time...?

My hd600 is a bitlackluster with the basses, but I have my home theater with two subwoofer if I want some basses

[lone flame]

Most people can't do it even neutral...

[tawdry gale]

It's ok if ur deaf

[stuck bolt]

An underrated pair of headphones are these https://a.co/d/6WrlbMR

[tulip monolith]

I spent some money recently…

I like how the red standby light turns off when the light in my room is off

Unit feels good quality

And it plays sound or something too

[glad creek]

One of the best piece of audio hardware one can get

[elder thistle]

I like the dt880 600r

actually serious bass (very tight and textured, not touchable by ft1, 560s, k702, edition xs, r50x)

very airy and wide

imaging great for most fps games

pretty resolving

I haven't tried a stellar45 beyer yet though

been trying to for almost a year

[pallid wind]

They’re here! I’ll have to wait after work to test them out but I did a fit test and it feels very comfortable!

[sleek lily]

I should get a jds atom to compare to my main amplifier on an oscilloscope

Here is a computer output at 500hz

Here is a proper DAC amp setup at about the same frequency

[muted imp]

I was... NOT expecting that much of a difference in sound. Damn!
https://www.youtube.com/watch?v=R14XeuTXwaU

Pretty certain I was also not the only to be in the dark about external synths like the MT-32, even in the 90s when DOS games and DOS-likes were still somewhat relevant to some extent.

[idle moth]

what's the best option to get a cheap amp to use with pc and headphones

i want to get dt 990 pro and getting an amp for it seems like something i'll need

even if i'll probably get the 80ohm version

my pc has a very cheap motherboard, and by proxy cheapest sound card
is getting a dongle enough?

[lean grove]

Honestly your motherboard should be enough but if it's not, then yeah a dongle will suffice.

[tulip monolith]

Yeah I’m going straight to endgame from laptop audio out lol

Gonna be nice for whenever I get monitors for my desk setup too

[glad creek]

Get a topping dx1 or else a dongle

[tulip monolith]

The ASIO driver seems to be pretty good too which is another reason for me

[glad creek]

The main advantage of the adi2 is the integrated p-eq for me

[green marsh]

i mean just buy a topping you know

[sleek lily]

Here it is with the function generator

As a more controlled variable

I'll buy a 3 channel scope in a couple weeks so I can get some better comparisons and export them to screenshots

[tulip monolith]

Yeah that too, very much a big selling point

[glad creek]

I believe their new offering has also an integrated p-eq option?

Which is cool

[green marsh]

yeah along with some of their slightly less recent dacs

that you can interface with with their web software

[glad creek]

That's neat

Though it's of no use for me... At least for how things are currently set up

Now topping pwizzzz make a 6 channels dac with really good dsp capabilities and dirac support

[pallid wind]

Man I should have gotten the Ft1 headphones first. These sound so good! Is getting a dac recommended for this pair?

[green marsh]

not really

theyll run off of anything

if anything just buy soemthing like an apple dongle or fiio ja11

[pallid wind]

I'm not used to having headphones with each cups having their own cables. Might take some time getting used to lol

I'll proably look into more flexible cables

Will certain type of cables get rid of the ehco when a cable hits something?

[green marsh]

yes or you could purchase some cable springs from mr capra https://capraaudio.com/products/capra-audio-cable-springs-cacs

or print them out yourself with access to a 3d printer

and tpu filament

some cables are simply more microphonic than others unfortunately

[pallid wind]

I see. It doesn't happen all the time as i mostly sit still

[lone flame]

Don't get the DT 990 😅

[pallid wind]

Funny enough I have the DT 770 Pro X waiting for return

[lone flame]

As Amp you could use an apple Dongle tho

[pallid wind]

I'm very happy with the bass on the FT1 so far.

[lone flame]

How much better are the FT1 compared to DT 770 Pro X?

[pallid wind]

I'm not an audio expert but the FT1 feels more full with more bass but it's not overpowering

There was something I didn't like how the DT770 Pro X sounded like. And I had comfort issues with it as well.

I still need to game with these

[lone flame]

Ye

FT1 gud

U can get a Capra Strap if u want more comfy headband

[pallid wind]

yeah i saw reddit posts of them

so far the stock headband seems comfy

[lone flame]

Guuud

[green marsh]

gotta support my boi brian capra

[sleek lily]

Got some measurements on an iem with the function generator and the computer amplifier sort of amplitude normalized

Within a little less than 1mv

[silk tree]

Hey guys My house has this prewired setup that I’m trying to use but due to the age of the equipment or my inexperience I can’t get it to work. The current setup is: Audio wires go to subwoofer, subwoofer manages that into a cable, cable plugs into receiver, receiver via optical plugs into TV, TV via HDMI goes out to linux laptop, which only sees 2 channels. Only the centre and left side speaker are working. which are recognized by right or left. Am I doing anything wrong?

[idle moth]

i heard mixed things about it

[silk tree]

also feel like it’s worth mentioning that the dolby digital light did come on when only the subwoofer was plugged in

[idle moth]

my current headphones already have higher trebles , and they're rather eh for what i plan to use them for, so it's an upgrade either way

if i won't like it then, idk i guess, refund i guess. i probably won't dislike them, tho, it can't be that bad right

[wild current]

Question: Has anyone ever seen what is effectively a vesa-monitor-arm mount for a monitor/speaker stand? Where you can easily adjust height and position?

[lean grove]

could be the reciever or the cable or the laptop.
cables could be old and if they go through the walls, they might have continuity issues
reciever might have some circuitry busted
laptop might not know how to handle the digital output to the reciever

[silk tree]

ok i guess i’ll try them all

[lean grove]

swap stuff out until you can isolate the problem

[pallid wind]

I have been using the FT1 lately and I'm enjoying it. I am noticing some crackling from time to time but everything is plugged in correctly. I am using a 3.5mm cable extender so I'm not sure if that's the issue.

[steel escarp]

If you touch the cable. You hear it. The handling noise is annoying.

Maybe u hear that

[pallid wind]

Hmm not sure. It’s not audible when playing like normal music.

[lean grove]

might be GPU noise. my comptuer does that. i noticed crackling anytime i would scroll a web page or play a game.

[pallid wind]

That’s interesting. Would getting a dac help?

I think I need to ditch this old headphone cable extender I've been using for a few years. What type of cable do I need for the FT1? I plug my headphone back into the motherboard so I need a long one

[tulip monolith]

The keyword you want is “dual 3.5mm”

[pallid wind]

Ah okay. I need one that's 6ft long probably

[lean grove]

If it has half decent power filtering, yeah

[pallid wind]

I think the crackling has been going down.

[pallid wind]

that acutally helps?

[livid ruin]

like 50% in my case

[pallid wind]

thats interesting

[livid ruin]

like when i tap my finger againt the cable i hear only a rumble, not like tapping agaisnt a rubber

[livid ruin]

yup it works, when i added more it's almost gone when hitting or tapping the cable with fingers

even the rumble

[pallid wind]

I see. It's not a huge deal now. Still figuring out this audio crackling I'm getting in the FT1 but I think it's been happening less often now

[livid ruin]

i just wouldn't spend $6 for one of these

not including shipping

[green marsh]

thats when you just print them yourself

[livid ruin]

how effective are they btw

[green marsh]

very effective

[livid ruin]

does the crackling happen with other devices/dacs?

[livid ruin]

and if you don't have printer you can make it yourself using rubber bands

[pallid wind]

Im thinking of requesting a replacement for my FT1 headphones. Only one ear cup has been crackling randomly. Or it could be the cable only?

[lone flame]

It's easier to get a nicely tuned headphone and EQ it than getting something that is already fucked up and trying to fix it

[tawdry gale]

it is possible that the cable is the problem

[pallid wind]

Yeah thats what im thinking. im still trying to find a cable so i can test it. the crackle doesnt happen all the time

if you have any recommendations that would be great

[tawdry gale]

An openheart cable

[pallid wind]

I did notice that the left cable has like a flimsy end at the connector compared to the right one

[lone flame]

put Right cable into left and left into right

[pallid wind]

I think it's still happening in the left ear cup after switching cables

[lone flame]

is it loud?

like is it possible to record?

[lone flame]

Does it sound like a "fart"?

Does it sound like this?

[pallid wind]

No it sounds like static or like a tiny soft pop.

[lone flame]

and its only on one side?

[pallid wind]

yes

[lone flame]

even when switching the cables from left to right?

[pallid wind]

I heard it for a split second

[lone flame]

that means?

[pallid wind]

Like the audio is fine but the pop comes for a split second and then its fine

[lone flame]

only once?

and compared to the music or sound. was it loud?

[pallid wind]

it happens frequently but at different time periods

[lone flame]

https://www.youtube.com/watch?v=FYjs7vsaSEw is it that?

That makes pop sounds

[lone flame]

dumb question

do me a favour. and put your phone near the headphone jack where you have plugged in the FT1 and calls that phone

ok is not really a question lmao

[pallid wind]

I am using an extender so could that cause issues?

[lone flame]

it can

normally not but longer cable = less resistent to noise or interferance

pop noises randomly doesn't sound like a Headphone problem to me

[pallid wind]

Okay so my first step is to get new cables that are actually long.

[lone flame]

Do you have a Apple Dongle?

or is it plugged into the PC?

[pallid wind]

It's plugged directly into the PC motherboard port

[lone flame]

that CAN also cause sounds like that

[pallid wind]

Oh....

[lone flame]

in short.
"Onboard audio Sucks"

[pallid wind]

So i do need a dac then? i thought it was optional

[lone flame]

it is.
like it works lol

But i personally would always take a DAC/AMP

luckly Apple Dongle are like 10 bucks

[pallid wind]

Do the FT1 use dual 3.5 or 2.5?

[lone flame]

3.5mm

[pallid wind]

It's hard to find cables on amazon.

[lone flame]

no aliexpress?

[pallid wind]

I could but their return policy isn't the best right?

[lone flame]

true

[pallid wind]

and its 50 bucks...

[lone flame]

Cables...
Tripowin, Moondrop, Linsoul

check these manufactors and sellers

[pallid wind]

I'd want something like this?

[lone flame]

do you have a 4,4mm connection somewhere?

[pallid wind]

Oh no never mind. Both 3.5 then

[lone flame]

[pallid wind]

it's almost 2am lol

[tulip monolith]

Yeah you don’t want a 4.4 mm balanced jack that will not work with your pc audio out

Haha

[pallid wind]

oh yeah the headphones comes with another 4.4mm cable which is larger

[pallid wind]

Would something like this be good to test or should I look for a proper dac?

[lone flame]

Apple Dongle

and u dont need a proper dac

apple dongle is proper

[tawdry gale]

ugreen's dongle dac/amp is bad

[pallid wind]

oh weird considering it has a lot of reviews.

[tawdry gale]

the impedance is too high

[pallid wind]

ah

[digital rapids]

Hey, I'm looking for headphones + mic for around 140$, (450 ILS)
I'm looking for a wireless headphones, something not gamer-y looking

I don't have anything special to ask but White colorway would be nice

[pallid wind]

This will work fine?

[tawdry gale]

yes

[pallid wind]

I've been talking to amazon and I'm able to get the headphones replaced. So I'll see if my second will be better before ordering these cables.

[tawdry gale]

sure

[tardy dune]

🥳
anyone else have them here?

[lone flame]

[pallid wind]

linus does

jokes aside, they look unique

[warm scarab]

driver failure is common in planars within the first week or two

[pallid wind]

It was on day one though lol

[warm scarab]

that is within the first week

[sinful wasp]

One message removed from a suspended account.

One message removed from a suspended account.

[green marsh]

ft1 isnt a planar tho

ft1 pro is

[warm scarab]

its like fiio's first planar

hifiman and audeze have terrible first weeks

audeze's tensioning is prone to breaking which makes a lot of their headphones self destruct early on

[green marsh]

they only said ft1 not ft1 pro so unless they cut off pro theyre using a dynamic

[warm scarab]

oh

this man should have bought an ft1 pro

[green marsh]

hifiman ft1 pro or fiio edition xs

[lone flame]

FT1 Driver

so beautiful ❤️

[lone flame]

Only if he doesn't want to EQ da bass

[warm scarab]

its literally a diferent driver type

[lone flame]

FT1 Pro problem

absolute dogshit THD performance xD

[warm scarab]

frequency response is not what should be coming to your mind when going from dynamic to planar man

[lone flame]

nah only reason why i said it bcs FT1 Pro's Distortion is just bad

and imo people woth FT1 Pro's should be cautios about seal

the Planar Bass bump is quite huge if there is a lack of seal

and that can cause the Diaphragm to distort

[warm scarab]

what amp do you have

[lone flame]

and THAT in the other hand can end in a damaged or dead driver

[lone flame]

A70 Pro

[green marsh]

[lone flame]

LMAO

[warm scarab]

must be the same headphone then

fr

[green marsh]

real

[lone flame]

NONO

Edition XS has better THD

so you can EQ it easly

FT1 Pro is just a mess of "farting bass" if you wanna listen to louder volumes

[warm scarab]

the graph bro

bro the graph

[lone flame]

iirc FT1 Pro has nearly 20% distortion at 20Hz at 104dB
and Edition XS is like at 2-5%?

[lone flame]

ye ik.

BUT it sounds different

[warm scarab]

bro the graph

the graph bro

[green marsh]

didnt you know graphs are literally the end all be all of audio

[warm scarab]

he did not know this

[green marsh]

smh my head

[lone flame]

Ashuran. u know 100% that you're trolling

[green marsh]

im just saying i wouldnt want either

[lone flame]

well. that's legit

[lone flame]

that's why i got LCD-2C and made it EVEN DARKER lmao

[green marsh]

ew

i need more treble not less

[lone flame]

DT 990 treble?

[green marsh]

i said more treble not all the treble

[lone flame]

well.
my Audeze sounds so neutral ❤️

with 3dB bass shelf

[green marsh]

ok mr raw flat enjoyer

[lone flame]

i think my HRTF has just a huge diff tbh

like its non average

see the lowest line in treble etc?

thats prob me

[green marsh]

idk about that

[zenith pawn]

no hrtf below 175 hz

head cant hear woof

[lone flame]

its because it doesnt really matter

[zenith pawn]

how did they measure those curves

[lone flame]

most variance starts at 3kHz+

[lone flame]

you put mics inside your ears. and measure it

[zenith pawn]

how expensive of mics do you need

[lone flame]

not really expensive

but doing it sourself at homeis difficult

you need quite the setup in total to do it precisly

[zenith pawn]

i need to make a machine to measure the frequency response of keyboard switches

[green marsh]

just buy a imm6

[zenith pawn]

im curious if its possible to measure the force curve of a switch with a contact microphone so you can see the full spectrum instead of just the 'dc offset' force

thats been one of my ideas

[green marsh]

how the fuck are you going to measure force with a mic

[zenith pawn]

what if u use the diaphram to push the stem

stick it right in the middle

[green marsh]

💀

they already have these fancy things called force gauges

[zenith pawn]

but the force gauge doesnt measure the full frequency spectrum

[green marsh]

??????

mf

their aint no frequency spectrum to a force graph

[zenith pawn]

there could be

maybe its not feasible to make such a measurement device

the force graph is just the 0 hz offset with no oscillation

imagine if you then spread it out to add all the frequencies like a contact microiphone could

oh wait you could probably just use a contact microphone and a force gauge simultaneously

[green marsh]

bruh

force curve is just how much force it takes to push down the keyswitch

it has nothing to do with frequencies and sound

[zenith pawn]

0 hz is the force though

sound is just force through the medium

wait

no it's not

i thought i thought of this

[green marsh]

sound is vibrations

[zenith pawn]

how did i forget that sound is displacement not force

so what if you theoretically have a material that deforms proportionally to its compression force and measure that

well then that doesnt measure the sound

[green marsh]

have you considering buying a calibrated measurement mic and then measuring the key presses

[zenith pawn]

i wanted to do something that would be really satisfying mathematically

but i dont think it would work now

[green marsh]

regardless literally everything changes how a keyswitch sounds

[zenith pawn]

yeah i meant measuring the switch on its own in isolation

perhaps i suspend it in air with a magnet

[green marsh]

💀

and how would you achieve that

[zenith pawn]

it has metal in it

boom magic

you can do it by freezing neodymium magnets

[green marsh]

it needs to be a magnetic material to do that

[zenith pawn]

i thought i saw it done with copper

since its paramagnetic at least

[green marsh]

idk

just sounds insanely stupid to me

for no reason

[zenith pawn]

yeah the correct thing is to put it into a 1.6mm pcb like normal and just measure it then

but i dont need the sound

[pallid wind]

I've been enjoying mine a lot in terms of sound and comfort. I just hope replacement unit will fix my issues.

[lone flame]

Yee
FiiO is extremly cooperative about stuff like that

[pallid wind]

I got it from amazon so hopefully it's fine.

[lone flame]

Amazon is cooperative too

mostly bcs of the lazyness and dumb coworkers that work there lol

And i can say that cuz im a Amazon empolyee as well lmao

[pallid wind]

oh damn lol

[green marsh]

as a former employee i resent that

[lone flame]

ofc not everyone is like that. But like uhhh. 70-80%? xD

atleast on my FC

[pallid wind]

I found this budget dac that I might get for my FT1. It's pretty small.

[lone flame]

you can get a external dac amp

like a full unit

i would go for a apple dongle. bcs its cheap and works perfectly fine

you could get a K11 tho

if u want a unit

[pallid wind]

I don't have spare ones laying around and spending money on an apple dongle sounds dumb lol

[green marsh]

its literally 7 dollars

[livid ruin]

i wouldn’t get it if there isn’t any third party testing

it’s nice they include a jitter chart but that’s only of the potential issues a dac can have

[livid ruin]

or is it this? https://www.l7audiolab.com/f/topping-dx1/

[pallid wind]

yup

[green marsh]

i mean its topping so you know the objective performance is stellar

regardless of any subjective opinions

[lean grove]

yes but will it save my marriage

[green marsh]

it will have you topping your marriage guaranteed

[lean grove]

[pallid wind]

sus logo

[pallid wind]

so is it a trusted brand? I don't know what these graphs are lol

[green marsh]

Basicallly

[livid ruin]

yes

[pallid wind]

I was also looking at audioengine though they're a bit more expensive

[livid ruin]

dx1 is alright, i couldn’t recognize it at first tho

[lean grove]

audioengine is dogshit

[pallid wind]

oh lmao

[lean grove]

they were mediocre 5 years ago and they havent improved while everything else has

[pallid wind]

Funny how I was about to get their speakers for my desktop setup too but I didn't go with them before

[lean grove]

dodged a bullet

oh wait i was thinking of the presonus speakers

[livid ruin]

audioengine?

[lean grove]

audio engine is still mediocre

presonus speakers are dogshit

[pallid wind]

I have limited desk space because of dual monitors so I was stuck with small speakers. Ended up with a creative pebble pro x or whatever their highest end version is

[livid ruin]

pebble pro x, uhh could’ve been worse

they’re basicly just pebble v2/v3 with fancy rgb

[lean grove]

as far as small affordable speakers go, the basic pebbles are the ones i dont have any complaints about

klipsch promedia 2.1 are also a good option.
but among a plethora of bad speakers, the pebbles are designed in a way that isnt overly ambitious or overly cheap

[pallid wind]

Well after some thinking, I decided to order my first DAC which is the Topping DX1 Mini. I think it's the best one I found for the size and that's usb powered.

[sinful wasp]

One message removed from a suspended account.

[tawdry gale]

hifiman has the worst qc and build in the headphone industry

[sinful wasp]

One message removed from a suspended account.

[warm scarab]

they are its just a consequence of tensioning and planars

if they extensively tested it sure they can detect failures before but its cheaper to just send a replacement

[tawdry gale]

spending more often almost never correlates with better qc and/or build in the headphone world

eg, the 6k usd hifiman susvara has the same chance of driver failure as the Edition XS and Sundara

HD800s (mrsp of 1799 usd) is built worse than the HD600(mrsp of 449.95 usd)

[sleek lily]

Only so much you can do to QC simple devices tbh. I see people in the keyboard space think everything has bad QC unless you pay $500 plus, not realizing the most that can be done for devices that simple is a power on inspection and a visual, which even the cheapest keyboards do.

[glad creek]

There is, it's topping, arguably the best brand of dac/amp for headphone there is

[tawdry gale]

fiio is better

[glad creek]

It depends product to product, depends on needs and depends on the price you get things, but topping really is pushing the limits usually

[tawdry gale]

all topping amps are quite clinical which a lot of people dont like

[glad creek]

This doesn't mean anything

[tawdry gale]

Topping just has the support of the objective people.

But the Fiio stuff is objective and has the subjective people liking them too.

[glad creek]

This still doesn't mean anything

but sure

if you are happy thinking that it means something

Go for it

[tawdry gale]

topping stuff has a more niche taste

[unique wind]

topping goated

i wish i had just bought a decent topping dacamp years ago instead of wasting money on poorly measuring schiit gear that died quickly

[glad creek]

exactly the same

[sleek lily]

Meh, it's really aimed at "audio science" people, which in this hobby is more audio pseudoscience tbh. There is a lot of ignorance of physics that goes on to make the "audio science" space overly simplistic and to keep it that way at all cost.

[warm scarab]

both topping and fiio are in the same ballpark

most of what fiio does is opamp consumer meme

most of what topping does is opamp audiophile meme

[lone flame]

@elder thistle https://youtu.be/kwvqxiBjr3M?si=gXEwDsrsd56zs0_O

[lone flame]

They are just transparent

They don't colorize the sound etc

So not like Tube Amp or others with anon linear FR

And if the FR of 2 AMPs is the same. They gonna sound the same (unless THD or Impedance diffs)

[green marsh]

youre just not audiophile enough to hear the differences

[green marsh]

imagine if they had shit cs to go with that

[tawdry gale]

oh hifiman will send u a replacement, but its very possible that it will die again

[green marsh]

this is why you buy used hifiman instead

so you know its working as proper

[warm scarab]

then ask for another replacement

after the first month the expected lifespan of a planar is incredibly high compared to before

[lone flame]

to hear what

More Soundstage?

[lone flame]

used Hifiman has better build quality than new Hifiman

because if the used one is like 2 years old u know they are build better

than a new unit that can break fastly 😄

[green marsh]

thats not how it works 💀

its literally the same build

its just actually been qc'd

[lone flame]

get qc'd boi

[livid ruin]

hifiman still uses plastic for their adjustement sliders

and a cheap one that likes to chip into black powder with use

cause you know… the other part of the slider is metal so…

but could’ve been worse, i really like their earpads for example

[green marsh]

i dont think its the metal on plastic thats the issue here

just shit plastic choice

[tawdry gale]

hd6x0 also uses plastic for their adjustment sliders, mine has no wear after 20 years

[green marsh]

cuz they actually know how to choose plastic

[livid ruin]

I think most of the metallic slider is clamped by the plastic in a larger surface area, without using adjustment steps

[livid ruin]

And implementation

[sleek lily]

Almost all amps will have a linear frequency response for the most part. I don't think that's a major point where they split from the average amp tbh.

Even otl should be able to have a pretty linear response in audible range with a competent designer.

[green marsh]

for example bottlehead crack

never mind the 1db diff between channels lol

[sleek lily]

Yea, as long as the designer knows linear circuits, they should know how to set the cutoff frequency range

Really, the factors I think matter most and I've noticed change drastically from good and bad amps are things that don't get focused on

Things like gain linearity

Especially load dependent gain linearity

[lone flame]

im not really a source meemer

[sleek lily]

But I get why stuff like that isn't focused in on as much. It's harder to design around and harder to explain the relevance of to consumers. Hence why most audio spaces overly focus on simple variables that honestly won't matter much.

[lone flame]

if i want changed sound i can use EQ lol

[lone flame]

Most important variables are FR, THD, Acoustic Impedance, Impedance

[green marsh]

there is no acoustic impedance in an amp

[sleek lily]

Thx won't matter on most amps

[lone flame]

ye. meant in general

like Headphones

[lone flame]

on amps you can put FR, THD, SINAD, Impedance

SINAD is mostly low on modern stuff

THD too, But it can cause problems

so FR and Impedance are more annoying

[sleek lily]

I wouldn't say that, especially not in the context of amplifiers

[green marsh]

on anything competent non of those will be out of spec

especially nowadays

[lone flame]

well yeah

like apple dongle

[green marsh]

outside of specifically designed things

[lone flame]

it performs well

[lone flame]

ofc. Tube amps are "objectivly bad" if you just look at the data

Some people prefer the characteristics that are caused by them

[sleek lily]

I definitely wouldn't say tube amps are objectively bad

[green marsh]

objectively as in thd and sinad

basically if youre amirm

[buoyant vale]

objectively bad for your wallet

[lone flame]

indeed

[sleek lily]

Almost any decent system won't have audible harmonic distortion

[lone flame]

listen to tubes.
there you have distortion

[sleek lily]

So it's slightly ridiculous to call something objectively bad if it doesn't perform as well an another device there.

[lone flame]

Tubes can have a pretty pleasamt distortion

[green marsh]

tell that to amirm

[sleek lily]

Lots of tube amps have a noise floor and harmonic distortions below the audible range .

Another think I think should be tested more is step consistency on dacs

[lone flame]

Tubes are bad on paper.
They wear out and over the time they will sound different

and when they are about to die it gets even worse

[sleek lily]

Depends on the criteria you're targeting. If it's just low noise floor or low the, yes. But realistically, those aspects shouldn't matter.

[lone flame]

only said they are bad on papers

[sleek lily]

Those aren't the only "on paper" aspects of an amplifier system.

[lone flame]

bad doesnt mean they sound bad

i have listened to some tube amps

pretty nice. i like the warmth 😄

they add a specific characteristic to the sound

only annoying part is.

You have the find the correct tube amp for your system

[sleek lily]

Tube amps tend to have a better dampened clipping and better handle sudden voltage swing off the top of my head. That's an on paper variable where they're just gonna be better. This is why I said the audio space oversimplifies these things to an absurd level where reality isn't applied any more. It's like what I discussed yesterday.

[lone flame]

Tubes sound different... And it can sound not that nicely on differentr gear

[lone flame]

Voltage fluctuations are irrelevant.

my power grid is stable

[sleek lily]

You aren't playing your power grid into your headphones

[green marsh]

i think he means in the audio signal

[sleek lily]

Or at least I hope you aren't

The Geneva convention probably covers not doing that

[green marsh]

plugging my headphones into the wall and listening to them (gone wrong)

[lone flame]

havent seen something bt that

ok so u dont mean electricity as power for gear good

so the sound itself

[lone flame]

so Transient Response?

[sleek lily]

Not necessarily

[lone flame]

what do you mean by "sudden voltage swing"

[sleek lily]

You play a signals in an audio amp

[lone flame]

yes

[sleek lily]

They aren't all a set RMS voltage

They're also not just a DC signal

These sudden changes are handled better on tubes generally afaik

They also overshoot less

Generally

[lone flame]

u talk about that?

like.
idk what you wanna say.

need examples like images etc

easier to understand

bcs i dont see the reason why that matters when the output is measurable good

and the most important output is FR

[green marsh]

flat fr with 50% sinad

[lone flame]

? explain pls

[green marsh]

50% signal 50% noise

[lone flame]

that is what he means?

[green marsh]

no

thats my response to most important output is fr

[lone flame]

ah thats what u mean

well for me. sinad is mostly in an inaudible range nowadays

like only Behringer and Steinberg fcks that part up

[lone flame]

but well. everything worse than 120dB Sinad is just bad

[silk tree]

Hey guys my sister wants to set up a super cheap surround system at her house but there’s no space beside her tv for the left and right channels, can I have the left and right audio come out the center channel and have 2 surrounds?

[lone flame]

so u want to use the front speakers only for center channel and 2 rear surrounds?

and TV speaker for Stereo?

[silk tree]

no probably not the tv speakers at all

just left right and centre coming out the centre channel

is that possible

[lone flame]

ah

wouldn't do that

[silk tree]

it’s just cause in the setup that it’s in the left and right speakers would have to go right beside the centre channel anyway

[lone flame]

well. it can work

but it will destroy the stereo imaging

[sleek lily]

I've had people try flat out telling me that oscilloscope readings are just frequency response. It's wild how out of touch the audio science space is. I blame the fact that there isn't an abet accredited audio program in the us though.

[white gate]

Depends on what you're showing on the scope

[green marsh]

i saw that you were talking about measuring square waves

[sleek lily]

What's wild about that claim though is how easily refuted it is. Like these are three sources with a flat frequency response which all exhibit wildly different behaviors. But even just knowing what an oscilloscope reads, clearly it's not the same thing.

[sleek lily]

Yea, you can deduce some aspects of response for specific frequencies from scope readings and you could eventually map out a response from an oscilloscope, but it's just wild to conflate them to being the same thing imo.

[lone flame]

How important are these "Voltage swings" BIOOC mentioned in an Audio chain?

[sleek lily]

Depends on your design goal

[white gate]

That first one wouldn't have the same FR, it's high-passed (likely a DC blocking circuit of some kind)

[lone flame]

like if i look at measurements on a AMP
And it measures flat.
why does that matter then?

[white gate]

Because basically all dacs/amps measure flat

The reasons they sound different aren't cause of FR

[sleek lily]

It's got poor holdup. Input voltage drops as it maintains the load.

[white gate]

But distortion profiles

[white gate]

Ie: it's high passed

[sleek lily]

In a sweep RMS remains the same within a very small margin

All amps will have a high and low cutoff, but not in audible range usually @white gate

But this behavior isn't from the f_h cutoff

It's just due to the power delivery

[white gate]

Ik, I'm just trying to illustrate that the main issue with using scope views is that people often read too much into them.

The number of people that see ringing on a square wave or the result of a DC blocker and assume that it's bad because it doesn't look as pretty on a square wave scope view is very high

[lone flame]

yeah.
most SS amps have a quite low THD (if you meant THD with distortion profile idk)
wouldn't that result in a "pretty similar sound to another one that measures similary"?

[white gate]

It's the same reason that looking at impulse response or CSD for headphones can be extremely misleading and cause people to go chasing ghosts or even prioritising bad tunings because it produces a more aesthetically pleasing IR

Most people are not aware that for a minimum phase system like a headphone or amp the IR, frequency response and CSD literally all show the exact same info and can be derived from one another

(and square wave/step response is basically just another way of showing IR)

[rustic totem]

Kind of like why the volume at 29 sounds better but I have to have it at 30

[sleek lily]

Yea, a common theme I've noticed in audio is obsessing over one misunderstood graph and not actually knowing how to interpret it or when it applies and when other stuff of relevance matters.

Part of why I wish gain linearity measurements per different loads were available more often for amps and k step linearity was more common for DAC measurements

[white gate]

Yep, and this is exactly why I (and the others at headphones.com) explicitly choose not to show impulse responses, CSD or group delay for headphones, cause it just leads to people misinterpreting stuff

Group delay is another massively misunderstood one

[sleek lily]

I definitely wouldn't say not to show them. I'd say it's better to show the information with a brief explanation of the exhibited behavior.

Kinda like a lab report

[green marsh]

Then the problem is people see the graph but won't read 😔

[white gate]

We did try, but it just led to the same confusions and arguments over and over no matter how often it was explained.

And for those that actually understand them, they can derive them from the FR themselves if they want anyway

[lone flame]

gosh i need to look more into DAC/AMP science

[sleek lily]

@lone flame Are you in college rn?

[lone flame]

nah 💀

why college when you can have an degree with ChatGPT lmao

[rustic totem]

Learning thermodynamics and other physics topics trying to understand water cooling is enough for me. I don’t even wanna open the crypt that is audio.

[sleek lily]

Ah, look into lectures on digital systems and linear circuits and electronics 1 @lone flame

[broken grotto]

detailed lab reports are only good for people who are interested in the whole thing.
most people only read the introduction and conclusion

[sleek lily]

Those 3 classes should cover most information you will need at an early level of understanding

[green marsh]

Fr

Wanna have it spoon fed to them

[broken grotto]

that, and some people don't care about the details. Was it good? was it bad? who cares what the details are, just tell me

[sleek lily]

It'll give you a nice head start if you decide to get into engineering in college too

Plus those classes shouldn't require any insanely difficult to comprehend math, so they should be perfect to learn before college imo in your free time

[lone flame]

fr. Probably something that isn't really worth anymore

only if you wanna work in that field

[broken grotto]

signals and systems i'd throw in there, too.

[sleek lily]

If youre in the us you can mostly get your college paid for by Pell grants tbh @lone flame

[lone flame]

nah im German 😄

so no pay2win

[green marsh]

Might as well learn vlsi while your at it

[rustic totem]

You must start at the beginning; chapter one; AC and DC electronics

I have to do franchisees in order

[lone flame]

on DAC/AMP i look at FR, Distortion, bit on sinad and the outpus specs like Impedance and power

not really whats actually happening inside

[broken grotto]

You can do signals and systems without AC/DC, it's mostly mathematics.

[sleek lily]

Nah, if they understand ohms law they can probably skip those for just personally learning the info in their spare time.

[rustic totem]

Nein! Must start at 10,000 bc now. With fire.

[sleek lily]

Not like they'll get tested and graded on understanding of something they are going for fun

[green marsh]

What no imd, dim or crosstalk?

[broken grotto]

linear time invariant systems, impulse response, frequency response, frequency vs time domain, stuff like that.

[lone flame]

oh those too 💀

forgot that lmao

[green marsh]

Or power on/off behavior

Or slew rate

[lone flame]

https://tenor.com/view/seriously-gif-23861497

well Crosstalk is valid too

dim and imd... idk if i should care about that

[rustic totem]

RF if you really want to bake your noodle

RF is witchcraft

[lone flame]

Temp is important to measure

[green marsh]

Nah

[lone flame]

hotter amp = warmer sound

[sleek lily]

No

Lol

[lone flame]

nah nah. ofc
look at tubes

(im obviously kidding here)

[green marsh]

We need amps operating in thermal runaway

[lone flame]

Average Temp in tube amps

(that's an fusion reactor, so basically ~150mio °C)

[green marsh]

Looks pretty cold to me

[lone flame]

or 270mio °F in freedom for the metric system haters

[sleek lily]

Really though, I think amps and dacs are mostly measured wrong in the audio space.

People over obsess over the aspects that really shouldn't matter and it's nearly impossible to find measurements for more complex but relevant axis of analysis

[lone flame]

im vibing with my D70S A70 Stack

[rustic totem]

Da heck is a mio

[green marsh]

like what?

[rustic totem]

Do planar magnetics all have that soda carbonation fizzing sound at times? My Maxwell‘s are doing it and I don’t know how to correct it. From what I read, it can be humidity or pressure changes. I already sent them to Audeze and they upgraded the planar magnetics. They said they had a newer revision and they installed them, but it’s still doing it.

[lean grove]

is it every time you move your head or does it do it when its entirely still

[rustic totem]

Sitting still and a lull in the audio

[lean grove]

might be an electronic thing. sometimes cheaper planar drivers crinkle anytime you move your head since the air pressure inside changes very slightly.
but if its when things stop playing and you're not moving your head, that might be an auto-shutoff clicking on and off to conserve power.

might be worthwhile to contact audeze support

[green marsh]

sounds like high noise floor maybe

[lone flame]

million but short term

in germany a "billion" are "Milliarden" and "Trillion" is "Billion" xD

[rustic totem]

It sounds honestly more mechanical in the exact way cavitation on the aluminum wall of the soda can. It will keep going. Damn peculiar.

[lean grove]

interesting. turn the headphone off and see if it still does it

[lone flame]

resonance?

is it there at quiter volumes too?

[rustic totem]

K I’ll keep listening

[rustic totem]

With audio playing I can’t hear it, it’s only when I pause or very low volume quiet parts

It’s very light sound. Exactly like cracking a can and putting your ear to it

[lone flame]

both sides or only one?

[rustic totem]

Both

[lone flame]

its exactly in middle of your head?

like mono?

[rustic totem]

equally as far as I can tell

[lone flame]

doesnt sound like a transducer issue

could be DAC or AMP

[rustic totem]

But only after it’s been going a while. First putting them on it didn’t do it

Like I just put them on and I’ll wait for it

[lone flame]

maybe its when they are warm?

[rustic totem]

Yea I’m thinking when the drivers are resting

[lone flame]

does it fade in slowly?

[rustic totem]

After being used

[lone flame]

or is it just instantly there

[rustic totem]

That I don’t know it’s like out of your sphere of conscious detection until your brain goes. Oh, it’s there.

[sleek lily]

Thd and frequency response. I see people in the audio space try to act like it's science to ignore physics and pretend those are the graphs of the entire universe lol

[rustic totem]

What’s a good way to stress planars? Bass heavy?

[lone flame]

ye

Planars normally have lesser possible excursion

[green marsh]

i meant the second part of that statement

[lone flame]

but also be cautious about that

because Planars are fragile af

[sleek lily]

Why would you want to stress test your headphones 😭

[rustic totem]

To warm them up and get them moving. I want to see when this sound will occur and I believe it’s when the drivers are resting after they’ve been used for a while.

I’m not playing at like 90 dB so I just meant I wanna get the membrane moving

[green marsh]

just do the classic white noise blasting

[rustic totem]

I believe it also maybe humidity in the micro climate like when you’re wearing them for a long period of time and your body heat and humidity is done up inside the cups

But since I just put them on, I figured I’d give it a strong test

[sleek lily]

Ah, I have been really honing in on how we should have measurements for k step linearity for dacs and load varied gain linearity of amps, but there are some other measurements I'd like to see too.

[rustic totem]

BFG Division. Just a light jog

https://tenor.com/view/rocky-if-he-dies-gif-24288315

Oh another good one; Wolfenstein the new order muhahaha

[green marsh]

is that like how stable is the frequency response is per volume?

[zenith pawn]

cant find anything on the internet about what a k step function is but i bet its something to do with whether you can play some sort of step function without artifacts

[elder thistle]

he can be as unscientific and careless as he wants. yes I've seen the video
I just wish he realized the consequences

[livid ruin]

i mean… 85% of headphone reviews are measurement-less

which sucks

so, people will not eat him for doing unscientific reviews

[elder thistle]

like its alarming that some people either hear techs and others don't, or perhaps some people have ears that allow techs to be changed with eq where others' ears dont. but thats the nature of the beast with subjectivity, and both sides should be preserved and excersized

my issue is that these people pretend its solidly founded and backed by science

[lone flame]

He does scientific reviews....

he has a "what i think of it" part and one "objective" part

and on the Forums you can see ALOOOOT more

[livid ruin]

@elder thistle watch some of the bose, logitech, etc. headphone reviews they’re basicly brainrot

[lone flame]

@white gate Your opinion? (sorry for the ping)

[elder thistle]

no

that is unnecessary

[lone flame]

He can see the message in the logs

[elder thistle]

my intent was not to start drama

[lone flame]

imo i find it quite funny how they can show lots of data while you cannot

[livid ruin]

i poorly expressed myself i meant as if his reviews wouldn’t be scientific and generally, the whole internet is polluted with not scientific shill overviews that are presented and written as reviews

[lone flame]

and its not about "making drama" more likely about correcting false information or add knowladge about topics

[elder thistle]

we are allowed to have negative opinions of eachother's beliefs and actions without rubbing them in eachothers faces

[lone flame]

yeah. i dont say that this is forbidden 😄

[elder thistle]

that only served to start drama

nothing was to be gained by pinging him and trying to gain a reaction

I dont appreciate that

he shouldnt either

[lone flame]

Marques Browniee does some uncientific reviews (nothing against him)
He doesnt really show any kind of actual Data like Gadgetrytech and Headphone Show etc

[green marsh]

some people simply dont understand techs are literally fr

in headphones

and iems

[lone flame]

"Minimal Phase System"

[green marsh]

minimum phase devices and all

[lone flame]

iirc

ye minimum phase!

[elder thistle]

they aren't for me

[green marsh]

ok mr copium

[livid ruin]

less not talk about him driving way too fast in places where he shouldn’t

[lone flame]

nah no names pls

like LTT here got themself an actual HAT to provide legit Data of headphones and IEMs etc

[livid ruin]

i think csds are important too

[green marsh]

they literally arent

[livid ruin]

resonances

[lone flame]

Resonance = FR

[green marsh]

from earlier today

Most people are not aware that for a minimum phase system like a headphone or amp the IR, frequency response and CSD literally all show the exact same info and can be derived from one another

[elder thistle]

sometimes its hard to assess slope from ft

[livid ruin]

yes but you cannod make csd out of fr, there is difference when your headphone does 100-90db at 3khz for 2ms vs 90db at 50ms

[elder thistle]

zeos takes a similar approach here by not showing fr in his reviews

[livid ruin]

oh i have seen his headphones

uhhh, certainly headphones

maybe not for $200 but $10 for the sound quality

[green marsh]

zeos doesnt do anything but listen and says he likes something

[lone flame]

ok then.
explain that...
Bass has the highest impact on excurion on audio systems.
if the driver moves with 3kHz in different amplitudes. isnt that the same as lower frequencies at different amplitudes?

CSD would only make sense on big systems with high excursion levels from what i read here what CSD is

[elder thistle]

at least he listened and describes what he hears

[green marsh]

it doesnt matter when every headphone is good to him

and every other headphone reviewer also does that

[lone flame]

thing is...
There are people that believe the earth is flat.
You can say alot. But it CAN (not saying he is lying) be false

[elder thistle]

objectivist channels generally only recite things from fr
