I recieved the M50s on Good Friday - and played them a lot right away to break them in (it cant hurt right?) The 60s came about 2 weeks later - so I have had them about a week and a half - but again, I have been using them quite a bit. I think it is possible that new drivers need a break in - but a requiring a month or more seems a bit silly to me!
I have a powered subwoofer, but did not use it at all during my comaprisons (that wouldn't be fair) and it really fills in the bottom on Rock music and HT.
I too find that "toeing" in the speakers a bit helps with the soundstage for good stereo listening. I don't notice too much difference though on HT soundtracks (guess it's all those other speakers that fill in the sound eh?)
Glad you enjoy your 60s as well. Maybe we should start a club or something - The 60s Generation! HA!
Enjoy!
