I sense that someone has made up their mind to get some M60s and is trying to squeeze into that any way he can, even if that means moving some other speakers around.

I got to this board while chasing my speaker selection and it is a pretty homey place. The input is insightful and of excellent quality. While my enthusiasm still outruns my technical expertise, I read ALOT of information here before everyone convinced me to part with my money. One of the consistent things I saw was a common thread suggesting that the M22s aren't the best choice for surrounds. The body of knowledge here points to the QS8s; a recommendation I support completely now that I have them.

Also, the suggestion about the RAVA is a pretty nice alternative to the HSU and SVS if they are problematic to acquire.
