Hey Guys, I'm sure by now there should be a thread about this... So if anyone can either point me in the right directions or offer help I would appreciate it much! 
 
My current setup on my work computer is as follows:
       Tidal - HiFi files - > Shiit Fulla DAC - > Bravo V2 Tube Amp - >ATH-70X/Grado325/DT880
 
On any or either of my headphones, at a certain mix of volumes (computer/DAC/Amp) I get to hear a hiss or white noise-esk sound that changes with the movement of my mouse cursor and or clicks. I'm sure this is very common but I haven't found the right descriptive words to find the thread on how to fix it. 
 
At any rate, I have tried with various volume settings. but ultimately it's generally present. Granted if I am playing anything whatsoever I can no longer hear this sound but sometimes at work I hit the mute button and stay on mute for some time and I get to listen to it and it generally drives me crazy... 
 
Help anyone? 
 
Thanks!

I had the same problem with my Modi, hissing and static when my CPU load would go up. The way to solve this is to get a USB isolator. Or, a USB hub that runs off of a wall socket to connect the Fulla.

Perfect! that makes sense and reasonable. I'll try with a powered hub I use to split one of my USB ports. hopefully that work. 
 
Thanks for the tip mate.
