Craigsub is my hero! The first actual test I have read about to check on speaker break in (aside from the PSB guy, possibly).

I tend not to believe in speaker break in. And "brain break in" makes a lot of sense to me. I added to the questioning of the "brain break in" theory just out of curiosity- to get more info like this.
