Thanks everyone for trying to help me.
Here's is an update to my situation. I went today to a local stereo shop and explained my problem. He suggested that I purchase a Audiophile APS unit. The 700 watt version retailed at 2700.00 Cad a bit out of my price range for now.
Just to set things straight I've tried disconnecting my cable entirely and the buzz still remains. The video is hooked up to my Monster Power Bar and from there to my TV.
All of my components except my amp are hooked to my power bar. The outlet I'm using is a switched one by that I mean a wall switch cuts all power. I've tried tackling this problem before by unplugging all house app and switching outlets the buzz still remains.
I thought some fresh blood this time around might give me some fresh insights.
Many Thanks
