To clarify if it wasn't clear before, my suggestion is to transform your current surround sound setup into a competent 2 channel setup via a good 2 ch amp and preamp. The receiver would be used for movies only (powering the center and rear channels) or if you wish to hook up some sort of surround music capability. this would have both an HT set up and a 2 strictly 2 channel set up in one system.
Home theater is car stereo brought indoors.What to say to that? what the hell are you talking about?
