I also have M80s and LFR1100's. My LFR's are very custom with a high gloss wood veneer in an exotic wood. Axiom was indeed very accommodating although the cost of the custom finish added significantly to the total price for the speakers. On the other hand, I don't imagine that the sound quality is any different than the stock finishes.
For music listening, do you mean stereo or multi-channel? And what kind of music do you prefer?
Have you considered the LFR's or M100s? My LFR's are amazing for music, even jazz at relatively low levels.
