Brad, it sounds like I'm in a similar situation. I'll be moving to the 990 (from a Yamaha 2092) in a few weeks in my TV room, which houses my ML reQuests and Cinema. The 990 will be used for HT and stereo listening.
I will likely also get the 7500 at the same time to power the front speakers, bi-amping the reQuests with the remaining channel for the Cinema.
