Good point, but it was the amp, not a bad cable, dimmer in the house, ground loop..etc. With this amp it would have been enough to just short out the selected input.

They look OK, and sometimes even work OK because you're swapping things around and maybe the bad connection goes good.
BUT, don't always assume it's the equipment . . . this is the 3rd or 4th time this year I've heard of customers with flakey interconnects causing hum !
The electrons in my neighborhood are well aware of which end of the interconnect is grounded and which end is floating--or if both ends are grounded like the gray vinyl ones that came in the box with your DVD player. Perhaps the electrons in other villages are less aware.

Perhaps your electrons are the product of illicit and unholy relations between protons and Maxwell's Demons? If so, I would be afraid. Very Afraid!
