Nice post Ajax. I don't know whether 'break in' is a real phenomenon or not. I know that the guy who designed and built my Thiel CS 3.6's says they need breaking in and I don't think he's looking to fool anyone ... they are GREAT sounding speakers. (ended up picking up a pair of used but mint CS 3.6's instead of going with the M80V2's and saved a few bucks.) I break-in components, but am usually not around for the process. I just leave 'em on set the CDP to 'repeat' and then when the weekend comes, kick back and listen to the music.
BTW, Ajax, thanks for the civilized discussion on the subject. You brought some needed class to this forum.
