I like M80 kool-aid
In my brief experience, A/B comparison with the v2 M60/M80s. I found the M80s to be cleaner/clearer at lower volume levels as well as having a better soundstage - more open. I found the M60s to sound much more like the M80s at louder volumes where they start to open up and the soundstage expands out beyond the speakers, but YMMV as each room will have an affect on these things.
FWIW, I like the look of the M60's better and once I stopped comparing the M60 to M80s I found the M60s to be more than enough. I sometimes still wish I had kept the M60s especially when I play some poorly recorded music as they were a tad more forgiving with poor source material, not by much, but just enough to be noticeable, at least to these ears.
