If you are using your speakers without a sub, there is a big difference between the M80s and M60s. After more than a year it still surprises me how low the 80s reach.

There are more subtle differences between the two in the midrange and top end as well. I felt that the 80s sounded noticeably more open/airy on the top end. I really noticed it with cymbals. This was in an a/b comparison at Axiom.

For me it was worth the $300 difference, but I wasn't replacing a good set of speakers like the M60.
