that my amps where sitting on top of a piece of 1/2" particle board which is part of a "kit made" home entertainment type piece of furniture, you know, two towers and a bridge across the top of a big screen. The large shelf, enclosed on all sides except the front, was acting like a megaphone. I moved the amps and no more audible hum from anymore than 2' away in either amp. I'm also going to find some rubber feet for the amps. Seems like I'm alwats learning something from this forum.
