What Mojo said. The M60s are too laid back compared to either the M80 or M11. The M60s are laid back enough to be called recessed, IMO. The M80 M11 difference is marginal at best, only noticeable on certain sounds and tracks.
I find it interesting that you find the M60 "laid back" while Alan @ Axiom says in another thread.
The latter (meaning the M80s) have a little deeper bass extension and output than the M60s, and are a hair's-breadth smoother on some vocals than the M60s, but the latter difference is only audible on instantaneous A/B comparisons and it's very subtle.
