Update: I did finally upgrade from E30/L30 to Geshelli JNOG2 / Erish (still have L30 for SE IEM’s)
using XLR’s with balanced DAC COMPLETELY solved all of my GPU whine and ground loop hum.
I couldn’t be happier and this is the best example IMHO of a reason to actually use a balanced setup casually on a desk. (vs. professionally in studio)
