Audiophile novice needs your expert opinion

I recently purchased an Acurus 125x5 for my home theatre system.I love the amp,but I have a small humm-buzz in every channel(speaker) My last system I had a Classe CA-100 pre-outted for my front channels and the reciever amplifying the center and rears,and it was dead quiet no humm.After experimenting I found it(the humm-buzz)was coming from my cable TV connection at the wall.(very close to the outlet for my HT)If I disconnect the cable line the humm-buzz stops.What is this from? And what can I do to stop the humm-buzz? I would appreciate any help. Happy Holidays- John

JOND- Thanks,Thats the first thing I tried and it did NOT work.When I unscrew my cable connection,the buzz stops completely.

I would NOT lift the ground from your electrical components. It is dangerous, not worth the risk, and there are other ways around it. I'm sure a search on ground loop will produce many threads. There is also an article posted on the SMR theater forums about it.

Try putting the preamp and tv power cords into seperate receptacles and getting them as far away as possible from each other.T
