You could order the M80 V2's and audition them against your M60's to see if you find the improvement you're looking for, since you have the 30 day trial period. As to the Q's, I don't think you should 'upgrade' to the V2's for the simple reasoning being that the surrounds are more for ambient sounds which are much less noticeable than your mains, so I think there would be less to discern between the older Q's and the new ones. Not really sure how much difference there is with the VP150 vs the V2 version so I can't comment there.
