Oppo 95: Burn-in...and Fan

I imagine jet fuel will work better with burn in than kerosene or plain old auto gasoline...if you have something that can ignite it.

Seriously...I want someone to explain to me in terms of physics...I'm talking p/n junction theory, conduction theory, energy wells, Schrodinger's equation, what is it that you think physically occurs during the first 100 hours of operation of a piece of electronic gear that makes it sound better at the end of that 100 hour period than it did at the start of it?

Mind you said piece of electronics gear is comprised of parts & components that have undergone QC testing to ensure proper tolerances on significant operating parameters and have undergone environmental stress screening to precipitate any infant mortality failure mechanisms.

jdub39 - not the answer I was looking for.

ESS does nothing more than precipitate latent defects -- bad solder joints, loose wiring, bad connectors and weak parts by over stressing parts mechanically, thermally and electrically. This is typically well beyond their normal operating envelopes with the objective being to induce failures in weak parts.

"Burn in" as used at the top of this thread presumes that operating new electronic components under normal stress profiles for x hours causes the normal operating parameters of electronic devices to change, always in a way that makes the sound get better. In other words, these are not RANDOM changes, even though the physical inputs are random...they always move in a direction of better sound, not worse sound.

Are you going to tell me you actually believe THAT? This is not the universe I live in.

To be clear, I fully agree such things happen with new speaker suspensions or any mechanical devices. But...the premise set forth by the OP is that the signal quality out of a CD player improves after the first x hours. Again...I ask...explain it in terms of physics. I don't think you can because I think it's a bunch of BS.

Guys, sorry, don't mean to come across as disagreeable and I understand everyone's here to exchange ideas and info. This is obviously a pet peeve of mine that occurs often in the audiophile community. If you think your electronics sound better after 500 hours than brand new then more power to you...as someone above said this could very well be caused by your believing it should sound better...the placebo effect. I'm going to stay firmly planted in my universe though. ;-)

I would ask you though to continue to try to explain to yourselves why, if an electronics component "drifts" or settles" physically in some way when new, why it always drifts in the direction of better sound. Even if I thought I heard improvement in sound of a new component, I don't know how I could logically explain it always getting better instead of sometimes getting worse if it was due to random changes in some physical parameters.
