Wrong example. Pattern recognition and AI have addressed these kind of issues for several years now. A video camera, a chip and software can infer and recognize an art masterpiece author with very high precision. I have such an example in our lab (not my work, though).
I'm not holding my breath for the same to identify the sound of silver wiring or the presence of a Bybee device.

Let's see...
John says sumptin...
Bob wrote sumptin..
Must be correct if two people say the same thing, no?
Walk into a room with ten people. Ask every one of them, what time is it?
They all give the exact same time to within a second. With that many in a room agreeing so closely, that MUST be the time, right?
You just walked into a room of special ops people, they just synchronized watches for a mission.
Moral...if everybody uses the same source either for information, or more importantly, misinformation, doesn't mean it is correct.
IIRC, Bob used to test and sort single conductor for directionality. Absolutely nobody on this planet at space laboratories, national labs, nasa, NIST (I asked), high tech industry, in the current range spanning attoamps to megamps, voltages spanning nanovolts to gigavolts, frequencies spanning DC to terahtz....nobody has ever reported wire directionality as something they see, worry about, or care about.
How is it high end audio is so far ahead of all the rest of the technical world??

I don't even know why they bothered; the Lorentz reciprocity theorem guards the fact that passive devices are reciprocal. Not even linearly electric or magnetic polarizable dielectrics won't break the theorem. Even if the dielectric ε and μ tensors are neither symmetric nor Hermitian matrices, the theorem still holds.
It is broken only by non linear dielectrics and/or time variant dielectrics. These extreme cases certainly fall outside the wire itself, so yes, theoretically cables with extreme bad dielectrics can be directional, but wires (in vacuum) can not. Such "directional cables" are certainly in the realm of the current measurement techniques, so if one claims "I hear it" it should be easily electrically measurable.
Oh, those were the days! When we could have a civilized discussion between people who heard differences and the skeptics. '-)
Bob Crump taught me about silver wire. Before that I found that it sounded too bright (glare) to be useful for audio.
I gave Bob my original copy of 'Hummel's book for his birthday. It was also my real first introduction to material properties that tied into what we were finding with wire differences. I still use it as a reference.
As far as frequency response is concerned, I seriously doubt that there are any differences between silver and copper that can be measured with conventional test equipment. I suspect that it must be an illusion due to something changed in the higher frequencies that is difficult to measure, so that the bass appears attenuated. Or perhaps it is something else.

Check out this YouTube video where Garth Powell talks about wire directionality and why it matters. Start at 37:00 in.

Time dispersion is easily measurable, this is more sweet talking BS. They might as well be selling Saladmaster.

More crap stupid physics analogies that have no substance whatsoever they fool only the fools. They need to sit before a jury of EM experts and testify.
Don't let let the facade fool you, last time I confronted one of these folks with hard questions in front of their marks they got REAL nasty.
You do understand that the best scientists, physicists, and engineers on this planet would spew milk out their nose if they heard this at lunch.
The guy has no knowledge at all on the subject. I am willing to bet he drew the short straw and had to do the presentation.
Nothing he stated is scientifically credible.
I assume you're getting credits for having idiots like me link to the video, right?

Of course because they are financially vested in their products and marketing talk, just like we've seen on this forum. 😉
Hummel. Is that the guy you corresponded with, then had him contact me?
He had a grad student contact me to try and explain how all this physics-type thingy workers with all then electron thingies in doze wire deevicees.
I told him where I worked, what I do, what you were espousing..like the Essex echo thing, the quantum chip, the wire directionality, near super conductivity...
Then offered my assistance to them should they need any help using niobium titanium, niobium tin, high temp supers, cryogenic diodes, superconductor splice joints, magnet fabrication and testing, warm to cold transitions, ultrasonic welding, motion control..gave him links to my work web pages IIRC.
Classic deer in the headlight moment. And no further contact. I think he went back to the prof and said "Houston, we have a problem."
These days are still fun, John. It would be great to sit down at a bar and relate interesting stories.

The man talking is Garth Powell who is the head designer of power products at Audioquest. He talks about his background in the beginning of the video.
I have no idea what you are talking about with "getting credits". I just posted the video links for information about what we have been talking about in this thread.
Some people can hear thing that can't be measured at this point in time, and some people can't. The ones that can are glad and are open to new ideas that can provide more musical enjoyment. That is what I like about this hobby, there is no end point, things continue to get better all the time.
I would hazard a wild guess that the answer is no. Two reasons for this guess:wlowes said:
1. I believe there is no difference, bass or elsewhere in the audio spectrum,
2. Anyone who understood his test equipment well enough to reliably make such a measurement of a very small difference(*) would understand enough to know not to bother.
(*) Even if I am wrong and there is a difference, it cannot be other than small and measuring small differences is difficult. Thinking you have measured a difference is easy.
Directionality could result from some substance coupling (and being modified by) some product of electric and magnetic fields (such as multiferroics?). Such substances are not usually part of audio interconnects; in fact it could be quite hard to make a detectably directional analogue audio cable even if we wanted to, so making one accidentally is quite unlikely.Waly said:
Above a certain number of hits, YouTube pays. I suspect this video won't go viral, but ya never know.
As to Rick, he may be a great power product designer, but his understanding of conduction within a wire does not even reach rudimentary.
It would be like me trying to explain circuit design to Scott Wurcer or John Curl.
(I know there are quit a few excellent circuit designers on this site, the I also cower at their wisdom and understandings.
