Excellent read. I am currently using M22's as surrounds (5.0 setup) and have been very happy with them in that role. However, I have never heard QS8's, so I'll trust your review \:\) Sadly/happily after my move in a few weeks the M22's are switching to another zone as a stereo setup... hmmm... opens up some slots on the roster.

This looks like it was a hell of a lot of work, thanks for sharing the results!
