Maybe someone already explained this, but I simply didn’t have the time to look through the whole thread. Due to manufacturing tolerances, a cable isn’t electrically the same from both directions.Very astute remarks...
The reason is that a cable is a transmission line and can be viewed as a distributed network of resistors, R(z), capacitors, C(z) and inductors, L(z) (and other electrical components like memristors), and where ’z’ is the cable position. But limiting the view to just R, C and L, it’s not hard to see that since a cable is a mechanically constructed device with small variations/tolerances in wire thickness as well as small variations/tolerances in the separation of the two wires, that these variations will cause a z-dependent random change on the incremental value (ie, df(z)/dz) of R(z), C(z) and L(z). Because of this, when flipping the cable around, one will see a different distributed network, though not much different, but nevertheless different.
So maybe those "directional" cables are known to exhibit a more significant electrical difference in one direction than in the other direction due to the manufacturing/design process of them and the manufacturer decided that one direction "sounds better" than the other and put an arrow on the cable?
In my precedent posts i insisted with Essien and Ansermet about the specific irreductible ability of perceptive consciousness versus measure technological pretense to explain the world of meaning and phenomenan ONLY by some chosen dimensions and parameters...
Now i will add a more theoretical physical background inspired by the idea of a great Russian scientist who wrote about TIME and energy and the anisotropy of the cosmos...
For Nokolai Kozyrev the DIRECTION in the universe between right and left and between cause to effect or between effect to cause are not EQUAL...and the diffreence is even measurable in his many experiments...
Here is the link to the article...

He is not a crackpot either if you look to WIKI...
I say that for the possible presence of a sunday "scientism" skeptic club member lost in this thread...
Then if the direction between cause and effect or effect to cause are different qualitatively and quantitatively and even measurable for Kozyrev, perhaps the human ears can perceive some microscopic effect "percolating" through smaller scale to them...Even if our actual instrument dont measure them...
Then wires can exhibit this difference in quality quantitatively between the origin and the end of a complete circuit ....
It is a speculation from me with Kozyrev for sure but.....
There is more under the sky than meet the ears or the microphone itself....
This does not preclude the necessity for a test of perception between cables or wire....
