Directional wires/cables


Is there any reason to support the idea that cables, interconnects or any other kind of wiring can be considered directional? It seems that the theory is that carrying current will alter the molecular structure of the wire. I can't find anything that supports this other than in the case of extreme temperature variation. Cryo seems to be a common treatment for wire nowadays. Extreme heat would do something as well, just nothing favorable. No idea if cryo treatment works but who knows. Back to the question, can using the wires in one direction or another actually affect it's performance? Thanks for any thoughts. I do abide by the arrows when I have them. I "mostly" follow directions but I have pondered over this one every time I hook up  a pair.

I’d like to say another thing. For the last 1,000 years, science has always been about challenging ideas, old and new. Science can give you some answers but rarely its entirety, There are 2 more questions for every answers that’s been made.

That is Science. If you think what you know is absolute, you are betraying Science on a fundamental level.

See, I couldn't even spell PhD correctly. I do not have the higher education of many in and around these forums. I do have big ears though. :) Thanks for all guys, it is appreciated. Sorry if people get angry over it. I for one, do not.

I am not 100% sure if cables can be directional or not, but if the manufacturer suggested a direction to install it in, I'd go with that.  

Thanks again to all who replied. I enjoyed all aspects of the discussion, even the cringe-worthy ones. 

Edit:. "Preview" shows the image. "Save" it doesn’t show the illustration of the coax cable . Anyway look at the coax cable illustration in the Link.

S represents the signal. Yes?

@rodman99999, I’ve used that Link many times trying to prove a point.

Imo, a SPDIF digital coax cable with a solid center conductor with RCA plugs is one of the best cables to use to check for cable directionality.
