Directionality Explained


I have read it argued against by those who think they know
Here is proof
Paul Speltz Founder of ANTICABLES shares his thoughts about wire directionality. Dear Fellow Audiophiles, As an electronic engineer, I struggled years ago with the idea of wire being directional because it did not fit into any of the electrical models I had learned. It simply did not make sense to me that an alternating music signal should favor a direction in a conductor. One of the great things about our audio hobby is that we are able to hear things well before we can explain them; and just because we can’t explain something, doesn't mean that it is not real.

There are two stages recovery and recrystalization . Recrystalization extinguishes offsets in the drawn wire making its characteristics very close to the rods before the drawing process. If the deformations are not gotten rid of as much as possible it decreases the conductivity of the wire. 
Hey, heaudio, I never said cryogenic treatment reverses the deformation. Nobody ever said it did. I’ll grant you there’s a change, but a change doesn’t mean some grand magical transformation. Cryogenics is mostly cold tempering. If a frog 🐸 had wings it wouldn’t bump its rear end so much.
Hey, Jonsey! Let me ‘splain something to you. Let’s say you take a thin copper sheet and you beat it all around on one side with a hammer for five minutes. Then you anneal the hammered copper sheet. Do you actually believe the copper sheet will be healed to almost It’s original condition? That doesn’t even make sense to a five year old.
What if we have a daughter?   

you mean, like with the fly kite guy?....hmmm....rather impossible...this would require at least 3 minutes intimate commitment on his side...but has not time....he is constantly on this board..

During first stage recovery after drawing copper wire there is an internal rearrangement of the microstrcuture, second stage recrystalization recovers mechanical and electrical characteristics. If this didn't occur the wire would have microscopic holes and deformations reducing conductivity.  Whatever you do with your beat up sheet of copper I hope it isn't making a flat cover for a table, if so then heating and forming  to restore to its it's original condition would help out.
