I would suggest going the M60 route and see if you really find anything lacking, I only noticed the difference due to a direct comparison to my M22s which prompted me to run them with the M60s I had ordered and found that sound more to my liking, thus the gtg with mojo and the review you read.
I soon learned to enjoy the M60s very much while waiting for my M80s to arrive. I suspect you would not even know you are missing anything at all with the M60s, unless very familiar with the Axiom sound and really enjoy the upfront sound. I have also since learned my M22s are more forward/open than the present M22s so the results of M22v2 and M60v2 might be less like the M80s than my attempt at the M82.
