Another thing you want to do besides the receiver settings and so on is play with speaker placement. I originally placed my M80's about 18 inches from the wall and loved it. Later on, I tried moving them out to about 3 feet from the wall. I noticed a rather large drop off in bass performance, so I moved them back and found they do perform much better 18 inches away from the back wall.
The QS8's are wall mounted, but you can still play with where on the wall they sound the most dynamic. My VP150 was destined to hang from the ceiling pointed down at me because there isn't any room beneath the tv for it. But luckily I think it sound great up there. I never did put it under the tv to test it though, I was afraid I might like it and be stuck putting it above the tv anyhow!
