Sorry, one more point. QS8s are felt to be extraordinary for DVD surround (maybe the best you can get) and pretty good for music, while dipole surrounds are pretty good for DVD surround and downright crappy for music.

I'm thinking that for video games the QS8s would be the way to go (based on a bit of experimentation with Doom3) but I don't really know for sure.

Is your dedicated HT system a different system from this one ? That's where you really want the QS8s
