I have a pair of B&W 804's running in stereo. I have a 13 year old Denon receiver right now, which I want to upgrade from. I know that the 804's are power hungry. I demo'd the B&W's on a Sunfire Theatre grand and it sounded good. I was initially thinking of a Sunfire Ultimate Receiver, but they are a little bit out of my budget. I was thinking of checking out Rotel. One possibility would be to get a pre-amp and one two or three channel amp first, and build up to a full surround piece by piece. I'm thinking that the first step should be in the 3k range. Any suggestions?
