I compared M60s and Studios about a year or more ago. Both I and the owner of the Studios had a lot of trouble telling them apart. Neither of us had much audio experience ant the time but still, if we were were having trouble discerning the differences, as opposed to imagining one was better, I think that this shows that both are very comparable. I'd be happy very owning either but I'm happiest knowing I paid less for such similar sound. His were a touch shinier if that is important to you as mine are the standard finish. Still, I get many compliments on the look of the Boston Cherry finish.
With great power comes Awesome irresponsibility.
