I am forever going back and forth on this issue. Some days my M60's are detailed and true, other times they are shrill and bright. I put this down to CD quality (I am still a little dissapointed that so many CD's fall into the 'poorly mastered' category - I tried to listen to Bat Out of Hell tonight and it was unlistenable.), and my mood (Psycho-acoustics?). The M60's will certainly spend a lot of time in my setup, but I am sure, as my usage is 80% music, 20% Movies that I will eventually move them to my zone 2 family room system and replace with something a bit warmer.
