I'm still a total newcomer when it comes to hifi, but I'm not regretting getting the XS at all. Is quite a big headphone, so if your head is super tiny it might not be the best fit. How it sounds without a dac? I've no clue, I was told to get one that could give it all the punch it needed. The FiiO K7 I bought for it could.
Speakers wise I was using a Logitech z623. I mean, it's a very nice and loud set for just gaming. But now that I had the nice headphones upgrade, I wanted speakers as well. I don't have allot of space, so all the audio monitors people suggested wouldn't fit or get blocked by my monitors. I went with the Kanto Ora, since they can also get mounted horizontal as shown.
I will buy a audio interface and a sub for it later down the line. I was thinking Motu M2 interface, and a Adam Audio T10s. But this can still be changed.
Sorry for the long yapping session
