I encourage all those interested in the phenomenon of "burn in" or "break in" to read my two articles at Dagogo.com entitled "Audiophile Law: Thou Shalt Not Overemphasize Burn In" and the follow up, conducted with even more variables, "Audiophile Law: Burn In Test Redux".
I suggest these articles have relevance to the topic of the thread.
