If the Denon offers preamp outputs for mains in XLR, that's what I'd try first. You can buy XLR fairly reasonable to see if it corrects the issue.
Ground loop/hum is the worst thing to try to correct. I wanted to go from my Marantz processor into my 2-channel preamp so the systems would share the main amp & speakers. I went single ended as that's what my preamp has for the bypass, I got a hum. I tried everything to track it down and eliminate it. I finally used a XLR connection between the 2 components and it cured the issue. Because the XLR wasn't designated as bypass I just have to set the preamp to the same volume when watching HT.
I use a PS Audio Quintet 10 outlet filter and high quality power cords, so I was quite surprised to end up with a hum issue. You can try one of those cheater plug adapters to see if that does anything, the ones that take a 3 prong to 2 prong.
