@Dr Tone, sorry for the off topic but I read (http://www.whatsbestforum.com/showthread...post425694) that you have your "TV, Xbox One, phono preamp, turntable, router and cable modem" all plugged in the same AC outlets/circuit as your Devialet.
I would seriously consider removing all the non-stereo equipment especially the cable modem (noise and ground loop paradise!!), router, TV and Xbox and move these to a different AC circuit if possible or behind some kind of isolation transformer.
Edit: I now see they're connected to a Denali, that should provide some improvement in noise isolation but other issues like ground loops may still exist. It's of course hard to be sure for me since I/we don't have the details.
