Hello all,

I'm currently running from my PC to a DAC, then out to a Valhalla 2 tube headphone amp, to my Senn 6XXs. I love the sound but with the music off, I hear the buzz every time I move my mouse. It's likely picking up the sound from the motherboard or the wireless mouse or some such thing.

I'm considering upgrading my DAC to a Schiit Bifrost which uses some USB tech that's supposed to "quiet" the input from the PC but I don't know if this issue can be resolved from such a thing. The Bifrost also has a linear power supply and my current dac is pulling power from the PC.

How do I get rid of the PC noise in my headphones coming from my PC?
