That's a nifty device. Have you tried plugging the ADA into the same (duplex?) outlet as the Denon?

Yeah, no luck there. I spoke with Andrew yesterday, and he suggested I could try unplugging the signal ground wire inside the ADA (chassis would still be grounded, so no safety issue). Not sure what screwdriver will work on the ADA chassis screws though, and I remember you saying that they were self threading, so may not go back in perfectly after initial removal

I really do feel bad for you. I wonder what's going on back at the panel to be causing this. Then again, it could be a bad connection right at the receptacle.

This is a long shot (really long) but try swapping ADA power cables.

It was the stupid RCA cables after all! Swapped out the 6ft 'high quality' RCA interconnects from PrimeCables.ca for 4ft AmazonBasics cables and bam, no more buzz.

Wow! Just wow. Is that because of better shielding, or what?

Not sure. The PrimeCables ones were supposedly double-shielded

They may have been badly built.

Possibly to long.

I have some of the Prime cables as well, quite nice. If you contact them about it there is a lifetime warranty. Though 6 foot is a little long for most basic applications that don't require such length.
Last year I decided to try Blue jeans LC1 much thicker with very large connectors. Seem really good but much higher price compared to P.C. brand.

Glad it was a minor fix as opposed to major overhaul.

Way to stick with it and work out the root cause. With that out of the way, how does the whole thing sound?

Do you notice any sounds quality improvement with the Blue Jeans LC1 cables? For 3 channels worth, LC1 are $99, vs $23 for AmazonBasics.
