Looks like Marantz wants to play. Cinema 30 is about to drop. Not sure what it has over the 6800, but it's $1000 more. Looks cool. Might have more open real estate in the chassis.

I have 2, 5X200 wpc channel amps, and the Axiom ADA 1250 3 channel. I could go full separate with a 13-channel system, but just don't think there is a compelling reason to do that. My room is set up for a 7.4.2 system. I might squeeze a pair of front heights in, but doubt it would help much.
