I would like to know your impressions of the QS4 vs the QS8. I'm in the same situation...I bought my QS4s about 6 months ago and I'm starting to wonder if maybe I should have purchased the QS8s instead.

Both Brent and JC at Axiom agreed that I would see little difference between the two models given the small size of my HT room. I've been using my system for listening to music with surround decoding A LOT more than I first anticipated. I think that music uses the surround speakers more than movies do...and I can't help but think that maybe, just maybe, my system would sound even more fantastic with the QS8s.

<<sigh...>> I'll just keep telling myself that the QS8s won't sound any different in my room than the QS4s...until I get the extra money to buy the QS8s \:\)
