I'm using RCA Monster ultra audio cables.
So I switched the channels around and swapped the RCA's and as I was doing so the hum went to almost gone, as long as the one on my center stayed stretched. As soon as I pushed it back on my stand the hum becomes very noticeable.
With that RCA removed from the ADA nothing just clean sound from my M80s. On any channel that I have tried on the ADA. My remaining surround channels through my AVR are not getting this hum at all.{Front height and sides}
It's pretty easy for my to try an RCA to mic.{XLR} though I've read that that can actually degrade the sound quality
