This sounds like an obfuscated explanation of dielectric absorption, does that matter for in audio band signals?
As for the directionality, I assume those who claim it to exist, probably have the OCC (Ohno Continuous Cast) conductor in mind which is supposedly invented by a certain Dr. Atsumi Ohno (1926-2017)?

Unfortunately there isn't much information about Mr. Ohno.
I am not a physicist, but researched a little on how electrons behave in conductors with respect to crystal lattices, grains and impurities, so it seems to have to do with crystal grain boundaries where two grains have different crystal lattice directions and therefore there will be a small "resistance" between the grains for the electron to overcome.
Now if we think of the OCC conductor where the grains are elongated and grouped together in a formation that reminds of the tent pins used for a tipi tent, and where each tipi tent pin grouping is stacked on top of each other making up an elongated conductor.
So if the electron would preferably take the path along inside one crystal grain instead of bouncing over to a neighboring grain because any irregularities would take higher energy to overcome, then it would mean if the electron is moving in one direction it also moves inwards (towards where the tent pins meet together) at the core of the conductor, whereas when the electron travels in opposite direction it would also move outwards, as a side effect when electrons move outwards they would also be more affected by the dielectric properties of the insulator.
Anyhow, if this is what happens and causes the "directionality" effect, if it at all is sonically detectable, then it is a sort of an asymmetric distortion effect, why would we want that?

What stumps me most, even if it shouldn't given the reference frame, is how Feynman's work (or the excerpts that are pulled out without much context), which follows code and is absolutely solid, is turned into "I believe something I can't explain and me and you can't measure so you must be stupid and your ways of measuring are no good."
A wonderful example of using terms which have meanings to make sentences which are meaningless.soongsc said:
If you think that Maxwell is "old tech" then are you suggesting that we should use the Standard Model version of quantum electrodynamics to design our circuits? I thought you were reluctant to learn undergradute physics, but now you want us all to use graduate-level physics?
That may be true for RF, where L and C dominate. For audio cables, where R and C dominate, the resistance also has an effect. Irrelevant, of course, for domestic audio.john curl said:
How would you measure a directional cable?soongsc said:
Ah! Now I know why Mr. Soongsc is so persistent in his confusion: it is a source of part of his income. I should have guessed, as this phenomenon is quite widespread.
Actually, there is. You can get a long way by assuming a classical gas of electrons. To do the job properly requires quantum mechanics. However, having explained conductivity using QM you can then use classical EM to explore the consequences when building circuits. Similarly, you need QM to understand how a BJT works; you don't need QM to design good circuits using BJTs. Physics is all about using the appropriate level of explanation; something which seems to be lost on non-physicists.Max Headroom said:
This is from someone who has not yet reached undergraduate physics, yet feels able to dismiss it.soongsc said:
Why? The source always remains connected, so the input voltage is forced to whatever the source produces.
Especially when he has exactly the opposite position.

an example that cannot be topped.

Basically, if you cannot hear the difference, I recommend not losing sleep trying to figure it out. I don’t try to use measurement to determine directivity because it is just easier to swap till it is right. If anyone wants to know why I started work on cables. Please feel free to read my blog.
Yes, I apologize for assuming that our two (three, one less vocal at least here) proponents of cable directionality thought in a manner that left some room for linear deductive thinking.
We haven't gotten yet to conspiracy theories but we're not far off. And of course backfire effect is probably in full swing. Ohhhhhhhh welllllllll...

Some time ago, talking with a friend of mine, I mentioned thah I made a Stax phone with integrated DAC. He screamed, "you are a fool? All audio systems need a cable to tune in!"
OUCH
Other thing, to fire the thread, what about connectors and metal quality? Or the use of dissimilar metals on interconnnect plugs? Some strrange effect will occur? Audio differences?
Questions
Who knows if all these reported claims are in fact connector related?
I prefer to use similar connectors makers and metals (eg. all Amphenol gold) for long life without one metal interacting with other and making surface corrosion.

One manufacturer did mention he once received such order. I assume it was you.[emoji6]
One audiophile did give me a set of connectors saying those were the best he ever tried, I sent it to a lab for a quick test, pretty much copper inside and out. The simplicity of the lines is what I liked. An RCA connector design is in the works hopefully it will work with my thin cables as well as the thicker ones. I do mention some of the reasons for a thicker cable on my blog.
Good. (IOW other listeners note the kinds of differences I'm talkin' bout.)
Yes. (Wiring direction throughout a system is an important consideration.)
Yes. (and no. So far I have fed only a fraction of what I have determined through long and vigorous experimentation.)
Thank you. (Not really a fair fight against those who do not understand what they do not understand.....besides which I'm old school peace loving hippy, share and care.)
Yes this is what I find.
