Is there anyone here that is using a 9.1/9.2 surround sound system? I currently have a nice 7.2 setup, and it's cool and all, but I'm always looking to get more out of my home theater experience.

I'm thinking about buying an Integra DHC-80.2 or the Onkyo PR-SC5508, to replace my current Marantz preamp, but was hoping to find someone, or a few people running a 9.1/9.2 setup so I know if the upgrade is actually worth it. I should point out that my home theater isn't in a dedicated room, my living room is pulling double duty. That's also the reason I have the hide-away screen; I need a regular flat screen to watch basic tv on, no use burning out bulbs for spongebob.
