Ok...here's an unsubstantiated and unscientific observation made after following the Axiom forum for nearly five years now(has it been that long already?)...but, going back a few years there "Were" a number of complaints about the "b" word and listening fatigue connected with the M60s. Enough of those complaints that I felt obligated to go with the M50s instead of the M60s back about a year ago when I needed to update to floorstanders.

If I were to be needing floorstanders today, I would instead probably go with the M60s, as the number of complaints against them has fallen to near "zero" in the last ten or twelve months.

In addition; we now know that there have been changes made to the crossover network of the M80, and while we haven't been given the info that the M60 has undergone similar changes.....
