My headphones:
beyerdynamic dtx 910
takstar 82 pro
koss ksc75x
sennheiser hd600
Powered by JDS labs atom and topping d10.
But mostly these days i listening on pair off mackie mr624 powered speakers.
Plunging powered speakers to a different outlet in a separate room fixed the problem completely. But now i have a long cord in the middle of my room ;). So most likely it's a ground loop issue. I will check with different cables.
I reticently purchased D10 and JDS labs ATOM. And i have a big problem with noise/hum when i plug d10 to pc. It's audible trough headphones even on low gain with volume at 11 o'clock. Do i have a faulty device or is it a problem with my pc?
