TinCan, I am glad you found a solution to the lack of a problem lol. I too have the same setup as you originally were looking at (M22's, VP100,QS4's) I am now saving up for monoblocks, why you ask for the upgrade to the M80s. I feel like an unwanted stepchild not having the M80's in the room. Not really but i'm just jealous.
OTOH, my setup truly rocks, was able to really open up the system last weekend and the 22's just maintained their composure. very impressive "bookshelf" speaker (bookshelf my butt)
