60 cycle humm coming from your cable TV. As a test try disconnecting you cable TV and see if that does the trick. If your cable is the culprit. Try a jenson transformer group loop isolator -worked for me.
I believe that you new amp has a 3rd prong at the IEC connector which draws addition current. Unfortunately, if your cable is not properly grounded, the 60cycle will make its way through your system and cause the a "buzz" sound in your speakers. I heard cheates plugs will do the trick but they are also considerd a fire hazzard.
