...the 360 degree sound field just seems to blend so much better with the QS8 tweeters at about the same height as those of the M80s.



I completely agree with you on that one. My surrounds are placed about 3 feet higher than my M80 tweeters. On the very last track of the Alan Parsons: On Air, a vocalist pans slowly from the center channel to the surrounds. As he does so, it sounds like he is sitting when he's coming out of my fronts and then abruptly stands as he moves to the sides.

Perhaps one way to improve this is to angle the surrounds down.
