I am running my entire system through a Monster HTS3600 powercenter. Lately I have encountered an intermittent buzzing sound from my speakers, and it is driving me crazy! I tried separating the AC power cords from the speaker wires (monster cable). I also tried to separate the coax cable away from the speaker wires from my DSS reciever as much as I could. When the problem first started, it was basically when I was using my DSS reciever, but now I can hear it when I am using my DVD player also. The only part of the system that is not running through the powercenter is my subwoofer, which is plugged into a different outlet because of it's location in the room. Any suggestions or help would be deeply appreciated!
