The Integra 9.9 has XLR outputs as a "convenience" feature, but is not a truly differentially balanced unit, to the best of my knowledge. As a result, other connected components may not be at the same ground potential, and a ground loop hum could result.
Ground Loop Hum with balanced XLR cables only
I've been working to track down a ground loop/hum coming from my speakers. I've got an Integra DHC-9.9 connected via XLR cables to a BAT VT-6200 amplifier. I spent hours trying all sorts of things to eliminate and finally I swapped out the XLR cables for regular RCA unbalanced cables and voila the hum was gone.
Any ideas why this would be?
