Hey Joseph, don't worry about all this "break-in" argument.. I posted something similar with yours here when I first got my M60s and got all kinds of attacks from the oponents of "break in" concept... However, I trust my ears and my own experience, and to tell you the truth, YES, I believe that my M60 sound much better now than the first day I got them. So is the case with at least one other audio equipment i got (my Rotel RCD-1072 cd player).
