When I listen to music it is 90% 2-channel with the m80's and subs. I don't really listen to any multi channel tracks. I have occasionally used 7-stereo mode or PLIIx and I think the Q's do a very good job.

I have heard that many like to use bookshelfs for the rear channels for music listening. However, for movies, nothing can give you the same experience as the Q's, at least for the side surrounds.
