I ran M2s on top of M60s when I was trying to figure out which one sounded "right" for vocals. The combination of the two sounded like the best compromise, but it mucks up your imaging a bit. I don't think I would want to do it with only one of the two channels though...

You have a 630, so you should be able to run 6.1 and IIRC there are some decoding modes which will matrix a 6th channel out of 5.1.

Why not stick the M2 in the back and see how you like 6.1 ?

[EDIT] When I was ordering Madeleine Peyroux's CDs I picked up Brothers in Arms and Ragpickers Dream at the same time. Just heard the intro to Money for Nothing on Axioms (M2s + sub) for the first time. Dang !!
