Hi Nick,

As an unabashed enthusiast of the M22ti's superbly smooth and linear midrange, and its excellent imaging and soundstage (vs. the M3ti's), I'd suggest going for option #2. You'd likely prefer QS4s as surrounds, but in the interim you could use M3ti's. If you like the M3ti's tonal balance, perhaps you should remain loyal to them in the front, but once you hear the M22ti's clarity, the M3ti's seem somewhat dull and recessed.
