What kind of mains are you thinking about, and what is the distance from center to listening position ? I went with VP100 and QS8 myself but haven't heard VP150 or QS4 so can't offer much comparison.

Axiom tends to match QS4s with M3/M40/M50 and match QS8s with M22/M60/M80. I thought that was just a pricing thing but some recent comments got me thinking that there might be a better tonal match with those combinations.

There are a few posts on here comparing VP100 with VP150... the pattern seems to be that in small to mid sized rooms there is no discernable difference between them while in larger rooms the VP150 sounds more open and clear (ie it can play at higher volumes and still sound good).

If you have a very long narrow room (ie surrounds will be close but center will be far away) that is an argument for VP150 and QS4, I guess...
