I would like to build a system for listening to Vinyl and watching my Blurays and LD's. I'd like a pre/amp surround sound processor that I can set up for listening to my old vinyl. Will use my Monitor 10's for the main speakers. Is this realistic or should I just build two systems. I recently bought a Denon AV receiver and am not happy with it. Who still makes the pre/amp type systems? What brands to stay away from and what ones to try and find? I was thinking 5.1 or 7.1 but don't see a point right now in anything more then that.
