Power Cable Break In - Such a Change!

     According to SOCRATES: "The only true wisdom is knowing when you know nothing."

     My version: "In order to know you don’t know anything you have to know something."

     Here are examples, in response to a previous post (mrskeptic’s):

     and:

     iow: YES, cryo treatment DOES fundamentally change the molecular/crystalline structure of metals (as well as a plethora of other materials).

     The problem with naysayers* isn’t that they’re ignorant (ie: that, "actual metallurgist)".    It’s that they, "know" so much that’s outdated and simply wrong.

                 *Those still basing their opinions on 1800s Electrical Theory

     More to the point of the potential affect of cryo treatments on our cables/components/systems:

the book on cable theory and design is certainly not closed...the video posted by @sls141 has appealing comic-like graphics, but that is not science, just an individual stating opinions without scientific evidence.  Even at our "advanced" date, the science of how  wires conduct electricity(notice I did not say how electricity travels THROUGH wires) is still controversial...if you wish to read mind-challenging science, read the article shown on Jeff Smith's website from FIDELIUM  CABLES.  Regardless, how many reading this truly understand the science?   one can be practical....what sounds better?  That should be what matters, right?

Second of all, when he says simply bending a wire changes it’s properties and therefore changes how your speakers will sound, he loses all credibility with me.

Bending creates stress that distorts the properties of a material. 

Tying a knot in a rope reduces the strength of that rope where it is bent. One doesn’t need to be a scientist to understand this.

Whether break-in is real or in the brain, it’s crazy to buy high end power cords new at retail or even 20 percent off (and have them sound bad for 150 hours) when they go for 50-60 percent off used and nicely broken in. I bought the AQ Hurricane for my AQ5000 on USA Audiomart for $850 (retail $1,750). 

aj523,

I hear Ya. It has taken me years to get to this point. I always call it the lunatic fringe. Stay with this hobby long enough and you too will start searching for that next best thing. Afterall didn't your Hurricane replace your previous cable?  Your already on the never-ending journey.

Remember, people pay $$$ for collectable pennies and such. It’s all about what we enjoy!

And, even used cables require some break in or "refreshening".
