Think you nailed it here. I've never owned a piece of electronics that exhibited "burn in" other than speakers, and even tweeters don't exhibit changes in T/S parameters or FR when I test them after a month or so. For woofers I'll notice changes in Fs with even 20 minutes of play time on them. I don't think the hundreds of hours period speaker companies suggest is necessary, but there could be some models out there that take forever to break in. Makes you wonder how they'd ever sound good in store though?
