Hi everyone,
I'm planning out my first "proper" desktop system, i.e. separate USB DAC and amp (of presumably good quality), and something I keep seeing mentioned is ground loops, or ground noise. I don't think I have any of this going on in any of my very pedestrian equipment at the moment so I'm just curious if there's any way to tell whether it will be a problem in the future? All of my desktop stuff is plugged into a single surge protector sound bar - computer monitors, the computer itself, and my old Wii U + gamepad charger, and 3DS charger - if that's of any significance. The amp would be plugged into the same, with the DAC being directly USB-powered.
Edit - I forgot to mention, I also use a power line adapter to get a wired ethernet connection to my PC from the inconveniently-placed modem. The modem side wouldn't be on the same circuit but the PC side is, albeit on a different outlet on the other side of the room and not on the power bar. I imagine that's very electrically noisy but it's not grounded so shouldn't transmit any noise onto ground, at least.
