Welcome to the forum
I would head over to the Hearing Things forum and look for someone nearby to ask for an audition. This way you can hear the M60s/M80s and decide for yourself which ones to get. Barring that order up the M60s and give them a try, if you are not overly happy order up the M80s, you will only pay for the cost difference between the M60/M80, Axiom covers the shipping as long as it is with in the 30 day trial period.
Ideally if you can swing it, order both, compare them and send back the set you don't like.
