I found that the studio 100’s (vrs III) sound is very akin to the M80’s. General impression I got, is that the 80’s have a tighter mid range, very similar base and a tad more detailed. I used the Pink Floyd DSOM disk when comparing. I do like the look of the 100’s better than Axiom, but not a $1000 worth. I should also mention that I heard the 100’s in a sound room and they were being driven by some pretty high end McIntosh gear and a CD player that I didn’t pay much attention to when I saw the $3500 price tag on it. Even with this gear driving them, I still think my set up sounds every bit as good (better with the addition of the sub). But to summarize all this babbling, the 100’s do sound very much like the M80’s. If you like the 100 sound, you’ll like the M80’s. Spend the $1000 you save on a good sub.
