I was reading this informative burn in faq http://www6.head-fi.org/forums/showthread.php?t=58157. At the risk of looking more stupid, I have some questions.

1) if a headphone/cable requires roughly 200hrs-300hrs. Should it be left on 24/7 or be given break periods. Is it damaging to the headphone to put it through 24/7 burnin for 2 weeks?

2) Im using my HT receiver tuned to FM for burnin. The receiver does not produce low bass, high treble or any tight notes. At the end of burn-in process, is my phones really burned in or do i need to play it some violin concertos and beethoven 1812 as well?

I've often wondered this myself. That's why I don't just burn in through my speakers' output, but just use my ears with my tube amp. I don't want to put unneccessary hours on my tubes just to burn in.
Plus, I want to listen as it happens.
But, yes, I've wondered if you'd get the lowest of the lows and the highest of the highs using a less than optimal source and amp.
Unless someone takes several sets of brand new headphones and breaks them in differently, we'll never know if it makes a difference.

IMHO burn in just makes the diaphram more flexible. To make it move as much as possible use something with low bass, as that makes the diaphram move more. As for breaks, do whatever you like. This is a black art, not a science.
