Don't hesitate to consider the M80's. Mine are being driven by an Arcam A85 and the sound is marvelous. If you haven't done so, check out the thread in the home theater section called "highs on the M80's". You will probably find it worthwhile.
I should add that I have an SVS sub tied into the mix which adds a lot to movies and does provide the "feel" of the base for music, which speakers on their own cannot do. (Really easy to get too much base, however)
