Have any published data you can point me to comparing any amps specs out of the box and after 300 hours use and revealing the audible differences? I'd also be interested in seeing the numbers after 100 and 200 hours as well. I always wonder how these burn-in numbers are arrived at. Why does something need 300 hours of burn in? What could happen between 200 and 300 hours? And why does the process then stop at 300 hours? lol. What if measurements are taken at 400 hours (assuming such measurements are ever taken, and I don't think they ever are) and its now appreciably WORSE than it was at 300 hours? And while the Bob Carver story is mildly amusing I suppose, it really has nothing to do with what we're talking about since we are actually talking about IMPROVING on published specs (via burn in) rather than simply reaching those specs.
