One notorious source of ground loops is incoming coaxial cables. Try disconnecting any in your system. If that solves your problem, get a ground loop blocker for it:

Thanks for the feedback... It does appear to have gotten worse the more I pushed things around back there. Now it is audible when watching a normal TV show, etc in the background. @dpac996 , Are you saying run from the preout on the 509X directly into the Main In, like a loop? So like play music from the DAC plugged into BAL 1, run a plug from PRE-OUT to the MAIN IN jacks right next to it? Will that damage anything, or at the very least tear a hole in space and time? @erik_squires there is no coax in my system unfortunately, just a whole bunch of DACs, amps, Apple TVs, Orbi satellites, Hue Bridges, and the like. It is quite a mess behind my BDI cabinet but it seems like I may have to start from scratch today unplugging things to get the bottom of things. @ricred1 - so just run a wire from the thumb screw on the AVM 60 to the screw on the 509X? I will try that too, thanks! Anyone have experience with the Emotiva CMX-2? |

YES. Totally fine. Just engage the "seperate" button and you are good to go. If no hum, you know 100% immediately nothing wrong with the 509 and that the problem lies with the interaction of mixed grounds with the home theater gear; This kind of stuff is a large reason why I have separated the home theater from dedicated 2 channel playback. It has been my experience over the years that you only get sub optimal sound on both fronts; YMMV! |
