I had a PS Audio HCA-2 that put a hum in the speakers even after removing the ground. Had to plug the amp right into the wall. I use a Tripp-Lite isotel.

The dealer recommended that I plug the speakers into the wall, and that solved the hum problem...but it left me withour surge protection for the speakers.
