Hiya,
I have been using this website for a while but never thought to make an account. I have found some help on this issue but I need it in some more simple terms as I am quite a newbie.
My setup is my PC connected by USB (which also powers) my Audioengine D1 DAC (which has a small built in amp). This is connected by RCA to my Little Dot MK2 tube amp which my Sennheiser HD 6XX's are plugged into. When I plug them straight into the DAC there is no background noise while no music is playing but when plugged into the amp, there is a small amount of interference type noise which spikes when I scroll with my mouse or open up an app.
I think the issue lies with the amp as adjusting volume on this changes the amplitude of the background noise, although I'd like to keep this on high volume to get full colour from the tubes.
I wondered if anyone could, in simple terms, explain to me how to fix this issue if possible (seems to be something to do with ground loops but I'm slightly puzzled on how to fix it) - https://www.diyaudio.com/forums/pc-based/325887-remove-pc-noise-using-usb-dac.html
Many thanks!
