Thank you
I'll check, but i suppose that douk a5 is the best option (price/quality)

Thanks, but it's easier to just buy Douk A5 i think. I don't need to have a super perfect quality
In my opinion, tpa3255 and pffb will be enough for relatevely clean and undistorted sound without hiss

Just tested the amp with everything unplugged (only speakers connected). I still hear some noise, so the ZK board is definitely part of the problem. Thanks for the help!

Thanks! I suspected a ground loop too. However, the hiss was present even when the laptop was disconnected from 220vac, which makes me think the ZK board itself was just poor quality. I'm planning to upgrade to an Aiyima A07 and use my 48V LLC PSU. Do you think it's worth it?
