In reply to:
There is absolutely a lot of perception of break-in, as admitted by Sushi. Hence my comment that almost everyone who hears break-in hears a similar set of effects: relaxing treble, maybe extended bass response.
I somehow overlooked this statement, but I just noticed a possible misunderstanding here...
I never said I myself have heard a difference due to speaker break-in (did I?). In fact, I have NEVER personally encountered with a convincing case of the effect of speaker break-in so far. NEVER. Of course, that does not prove or disprove anything.
Rather, my point is that the very observation that "almost everyone who hears break-in hears a similar set of effects" makes the whole argument for the existence of a physical change very dubious.
