I was a synth. aficionado back in the late80s & early 90s and used to have a pretty decent MIDI home studio.
The only thing I can think of that would not make the M60 an ideal reference monitor is that they are very sensitive to placement. If what you’re looking is a close reference monitor I would suggest the m22 instead (although I never heard them) or even the M3.
