I hadn't considered 5 channel since I'm still negotiating with wifey on placement of the QS4s. So far, not having experimented on a wide variety of music genres, I like the music without the center channel better. Maybe it's because the M22s are up higher than the VP100. I'll do some more experimenting though. Thanks for all the thoughts! By the way, I'm extremely happy with my speakers so far. The M22s sound fabulous with the music I have listened to.
