Do speaker cables need a burn in period?

What’s perhaps even more disturbing, to anyone but especially the skeptics is the use of home feeders for treating cables, CDs, LPs, CD players and all manner of audio related things. Obviously -20 degrees F is not nearly as low as cryogenic temperatures -300 F nor is it low enough to significantly change the physical characteristics of copper or silver wire or the cable jacket. Nevertheless...

You might recall HiFi Tuning data sheets showed differences in resistance between cryod fuses and uncryod fuses.

There is probably nothing more touching in the audio world than when one skeptic reaches out to comfort another skeptic. So sweet.

@lanceo and @azbrd   Living in the Post Modern World is gonna challenge you guys to your core.  Good luck with that!

Ah, the the resurgence of the Post Modern World Vision.  My goodness, I hope not...  "The bounds of science can not contain the human mind" (Toynbee).  

Well hifiman5, your hero was also credited with the quote, Civilizations die from suicide, not by murder.  Seems to me that embracing a false reality, especially with how the physical world actually works, is far more threatening to social development.

So, back to the subject at hand: Do speaker cables need a burn in period?  Answer: Only if you believe the advertising written by Cardis, AudioQuest, SilTech, WireWorld and a few others.  I think Albert Einstein must have been in the midst of just this sort of conundrum  when he complained to a Princeton, NJ newspaper reporter, "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."
