So let me go through my setup:
1. APC Surge Protector
2. Three prong power cables powering my Topping A90 & PC
3. Micro USB cable powering my Schiit Modius through the USB port on my PC, connected to the Topping through RCA cables (balanced ones coming in the mail soon)
Through this setup, if I have the volume up to where I'd usually listen to it with my HD6XXs, the noise is much more faint, but definitely audible. But, if I turn the volume/gain up to high levels and just mute the PC completely (like, dangerously high levels imo), I can hear noise from my PC loud and clear, which will vary under load. But with my HD 800S (don't have them currently), this noise was much more audible at lower volumes over the amp's balanced output. I tried plugging in the DAC through a Schiit Wyrd and it didn't help. Is there anyway to fix this issue? I know I could use the optical out on my motherboard, but for DSD over DSD64 (which I'll listen to on the Topping D90SE I'll be getting next week), I can't use optical, so I'd prefer to have this issue fixed instead of worked around with optical.
