I was going to move my Marantz SR6012 into my 7.3.4 theater room, but decided to keep it in the game room in a 7.1.2 configuration. For the theater room, I'm running a Marantz SR8015 since I wanted a "one and done" for more than a few years. I have the front channel speakers running pre-amp off the Marantz to a pair of Odyssey Kismet amplifiers (one stereo for L/R, one mono for the center).
Definitely not the most cost-conscious setup, but certainly much less expensive than some other systems I've seen.
