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.

Just saying ...

What a coincidence! Just saying these guys also have a science background.

Bybee Technologies – Founded by Jack Bybee – Physicist

Jack Bybee’s first commercial products emerged from Cold War-era military-industrial research. The stealthy shadow contest of nuclear submarine detection, location and evasion demanded ever-quieter circuits, lower electronic noise and greater signal-to-noise ratios. Practitioners summed up the problem as: “reducing 1/f noise, from DC to 2000hz”.  

Bybee’s technology involves exotic blends of rare-earth metals or their isotopes to reduce electronic noise in circuits. In the mid-1990s, Bybee’s AC filtering was among the first of its kind to use exotic doped materials instead of transformers or balanced power, which made it a novel concept at the time.

Jack’s science and physicist background gave him the understanding about negative effects of quantum noise. Link here.

 

Purist Audio Design – Founded by Jim Aud – EE & Physicist

From there, I earned my Electronics Engineering degree at Brescia University, and would later study Computer Science for almost two years at Westinghouse. Then I came to South Texas Nuclear, and studied what they’d call today nuclear physics. Link here.

 

Shunyata ResearchFounded by Caelin Gabriel – Research Scientist

 

Caelin Gabriel is a former US military research scientist with a background in research and design of ultra-sensitive data acquisition systems.  These systems were designed to detect extremely low-level signals otherwise obscured by random noise, requiring years of intensive research into the sources and effects of signal and power-line noise interference.  Link here.

 

Silversmith Audio – Founded by Jeffrey Smith – Engineer

CEO/Designer Jeffrey Smith is a Wyoming native and graduate of the United States Naval Academy with a Bachelor of Science degree in General Engineering. He also earned a Master of Science Degree, With Distinction, in Defense and Strategic Studies. Link here.

 

MIT Cables – Founded by Bruce Brisson – awarded 20 USPTO engineering patents.

MIT Cables founder Bruce Brisson began purposely designing audio cables in the 1970’s after encountering the sonic problems inherent in cables typical of the day. Link here.

. . . It would seem to me that the best construction using drawn cable would be that each of the two conductors be a pair of wires, arranged in opposing directions to minimize the grain structure distortion.

Does anyone know of a manufacturer that does this . . .

Yes, several cable manufacturers. A type of bucking winding.

Here is a video for the LessLoss C-Marc series. Scroll down this page for more info from the LessLoss website.

Here’s another Lessloss video that shows how the C-Marc cable is manufactured.

These types of technical discussions seem to be about: What is known and can be measured vs what is yet to be known and has not yet been measured.

This reminds me of the America’s Cup Race in 1983 where Alan Bond’s Australia II snatched the America’s Cup away from Dennis Connor’s Liberty.

At his disposal, Dennis Connor had a phalanx of physicists, engineers and naval architects – as well as the full use of the U.S. Navy’s science labs for testing and measuring hull shapes and designs.

On the other hand, Alan Bond had just one guy, Ben Lexcen. And Ben outsmarted them all.

With his out-of-the box thinking, he discovered new insights into fluid dynamics. He single-handedly improved upon centuries-old nautical hull designs with his winged keel. His innovation can now be measured. Decades later, this technology has led to super-fast hydrofoil racing designs.

“Untold: The Race of the Century” is fantastic documentary about this thrilling sailboat race. It’s on Netflix.

As a life-long sailor, it wouldn’t be surprising to me if electrical waves have similarities to other types of waves found in aerodynamics and/or hydrodynamics. As a kayaker, it also wouldn’t be surprising to me if dielectrics in cables have similarities to the rocky riverbed in white-water rafting.
