I'm using a DAC/amp combo (one single unit) that's connected directly to my PC with a USB cable that carries both data and power. Everything is fine when I use regular AUX cables, but problems arise when I use a cable that uses an interconnect. The current setup looks like this:
[DAC/Amp] to [3.5mm male to 4 pin mini XLR male] to [4 pin mini XLR female to 3.5mm male] to headphones, interconnect is bolded
When I use this setup, I run into issues that the DAC/Amp maker identified as a ground loop based on the symptoms:
-I hear electrical pop noises when moving the cable
-Positioning the cable in certain angles and squeezing it can cause really loud, continuous static noise
-the DAC/amp heats up and gets MUCH hotter than it normally does compared to when I use another aux cable
From what I've read, ground loops are caused by stuff like power sources being separated, but I don't get how that can apply to my situation when it's a single unit that's connected to my PC with a single USB cable.
Any help would be appreciated!
Edit: It's probably not a ground loop issue after all - I got in contact with the company that makes the cables and they basically admitted fault and said it was because the cables don't have some kind of "shielding" that is necessary in my situation.
Still looking for possible solutions on my end though
