I guess I would cast a vote for QS4s if only to give you more flexibility in the future. My QS8s only arrived a couple of days ago so I am not able to say definitively which is better. I can say there is a huge difference and that the QSs "disappear" just as everyone describes -- you aren't aware of having any surround speakers at all, and you wonder if they are even doing anything, until you switch them off and suddenly the room gets real small and the sound collapses to a little space in the front of the room.

With M2 surrounds it's much more obvious that you have surround speakers and you can hear things jumping around from one speaker to the other -- with the QSs you just sort of "know" something is behind you and it's easier to place the sound between the speakers.

I'm going to have to do more testing before I can say for sure (including playing with levels a bit for both QS and M2) but right now I'm leaning towards the QSs.
