I had the same problem when I hooked up my amp to my SS reciever and the hum was very noticable, tried changing interconnects, power cords, speaker cable, nothing worked. Well I got the cheater plug at Home Depot for 50 cents and boom the hum is non-existent. Thanks for tip, I will pass it along.

You can also use a PC with a SWITCHED ground, disturbing the power connection less than the introduction of a cheap "cheater", and safer than removing the ground pin on the AC male, as is now suggested by a manufacturer! (DISCLAIMER: I assemble DIY PC Kits offering said switched ground.)

Hi,

The cheater plug didn't work for me, but
Xantech 634-00 Ground Breaker did the trick the speakers are now dead quite (when not playing : )

Thanks,
