What is your sw receiver gain set at on the denon? The subwoofer crawl is an excellent idea.
It sounds like you have a groundloop as well. Do you have a 3 prong to 2 prong adapter (cheater plug)?. If you do, use it and see if the hum goes away...if it does then you have a groundloop within your system.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
