Mitch, welcome. It's unlikely that you'll find someone who's done the blind tests with the 906 that you mention, but that shouldn't really be necessary in arriving at a decision. The M80s are slightly above average in sensitivity and therefore need a bit less power than many other speakers. The 906 has a quite powerful amplifier and can drive the M80s to beyond a safe listening level except where the listening position would be exceptionally distant from the speakers. The 906 and the Epic 80-500 should allow you to enjoy the sound that you're looking for.
