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 like this quote from Ralph Morrison.

If we accept the idea that fields carry energy in space, it must be true at all frequencies. That is the law. If it is true for light, it must also be true for 60Hz power and at DC. For utility power, the energy travels in the space between conductors, not in the conductors. This is not the picture presented by circuit diagrams, where energy seems to be carried by conductors. In digital circuits, the signals and energy travel in the spaces between traces or between traces and conducting surfaces.

Buildings have halls and walls. People move in the halls, not the walls. Circuits have traces and spaces. Signals and energy move in the spaces, not in the traces.

 STILL a topic in 2025?

The most impressive thing about this thread is the number of responses in a relatively short time span.

Carry on.

Fun read while I enjoy my fresh ground dark roast listening to newly acquired music from the used bins at my local store.

 

  

“..could have been pre broken in.  Break in is real.” no proof statement again.. yes, there is aging processes in any device s involved in sound amplification and transmission, pareto is in tubes/SS/Dig not wires. cables exposed to aging as well, but, aging makes wires performance degradation with time, due to dielectric hardening and resistance of wires increase.. connectors have own life in this process, and depend on both interconnected sides design, finishing / plating / terminating issues. 

cable can have directionality if cable is unsymmetrical in mechanical or electrical sense, such as having additional filter clamps, special optimized connectors different on two sides, or different cable prep. 

 

Several of my cables are directional, and although I cannot hear the difference, I follow the instructed direction. For unmarked cables, I use an ad-hoc approach, ensuring that the label aligns with the flow of electrons. I believe in it—why not? It’s doing something in the background, and the cumulative effect might surprise you, right? Even if it’s snake oil, there’s no harm, right?

“..the label aligns with the flow of electrons” electrons in cable move only for DC connection! All audio signals’ are AC, thus electrons are only shaking both ways, and generate EM wave moving from source to load! Not absorbed EM wave in impedance mismatched signaling schemes, such as “RCA <=> high input impedance and low output driver impedance”, creates reflections, thus time domain signal distortions.
