In reply to:
It's infinitely easier to prove individual speakers DO exhibit break-in, at least subjectively, and maybe to a lesser degree, quantitatively.
I agree that it is always MUCH easier to prove something DOES exist. So, have you actually proven that your speakers (or any other speakers) do exhibit a break-in change in ANY CONVINCING WAY? If so, please describe the proof, either your own or somebody else's. I fully accept "subjective" observations as proof, AS LONG AS it is well-controlled.
As I stated in the AVSforum thread linked above, I myself is open-minded about this subject, and awaiting for a convincing proof either way. So far, I have never seen one piece of convincing evidence. ZERO. So, I tend to doubt its existence in the meantime -- and I repeat, this last part is my own FAITH. I am fully prepared to change my view, AS SOON AS somebody provides a convincing evidence showing that speaker break-in is not merely a psycho-acoustic phenomemon within your brain.
