TNT, sorry but you’re wrong. The signal does travel through the cable. As I already pointed out the signal in audio cables is alternating at the instantaneous audio frequency, it’s this signal that eventually makes the speakers play music. So, in reality the signal in audio cables is the audio signal. It takes two wires, each one carries 1/2 cycle of the audio signal. Together that make one full cycle of the audio signal.
See if you can guess why fuses at the point of the AC power coming into the amplifier are directional.
I never said the audio signal travels through a power cords. So stop putting words in my mouth. But some signal is traveling through power cords. See if you can guess what it is.

You appear to be conflating a complementary output stage with cables. Not the same thing at all.
@Guerilla I agree that further talk about cable directivity is not where this thread needs to go from here. So far the claims of directivity have not be credible enough to continue with.
No, you’re wrong, each wire + and - contains 1/2 of the audio signal - one wire + makes the speaker diaphragm go out, the other - makes it go in. I can certainly understand why you would prefer not to discuss directionality.
There is also the point that all these signals are AC. So how far do the electrons in the copper move for a typical signal?
Well for a decent 12 gauge loudspeaker cable carrying 10A peak (So 400W into 8 ohms) the electrons shuffle one way by 20um then shuffle the other way by 20um.
For an interconnect, the electrons shuffle back and forth by less than the wavelength of visible light.
But this tiny audio effect is superimposed on the Fermi velocity - which is how fast the electrons are randomly moving around - which is at a million meters per second.
So the electron gas is a highly dynamic random environment, with a very very small ac audio signal impressed on it.
Just putting some basic physics out there.

Still trying to sell snake oil, looks like. This time appears that he's just trying to see if he can make up wrong stories of cause and effect for some EEs and get away with it.

The free electrons are the charge carriers. Their drift velocity is about a meter/hour. That works out to about 1/100,000 of an inch, depending on the instantaneous audio frequency. Thats how far a free electron moves at one time. Obviously the net velocity of free electrons is zero. Current is calculated based on the number of free electrons and the wire diameter.
Geoff, you have shown a history of what appears to be dishonesty, as shown by your semi-defunct website. You are being given a chance to show you have turned over a new leaf and deserve to be treated accordingly. However, every technical explanation you give is wrong. Can't you go read a technical book or article and parrot it back correctly just once? Why do you keep making stuff up and insist you know what you're talking about? Nobody here is being fooled by it, so why keep doing it?
More name calling, this time pretty low.. You can’t argue the points at hand, so maybe you better take a break. I always tell the truth. You’ve been following the wrong sheep.
Geoffkait,
You’ve taken the ample opportunity to tell and defend your extraordinary directional hearing experiences.
May I conclude that when you couldn’t convince after ca. 19 postings it’s about time to call it a day.

That's comforting, that you can hear a difference, I think I can but I think I was getting ear fatigue last night.
lol, classic comment, thankyou for a good chuckle, I guess I would never know, eh! The amplifier sounds very nice into speakers!! To be honest I am not sure what I am listening to, I am puzzled by the obvious "distortion" because I am comparing 2 loaded amplifiers, the only difference is the cable, and puzzled by the way bass transients sort of sound "blatt". I do perceive some changes in the sibilant quality, I think, and that was the kind of thing I was expecting to find.
I don't, and I am less confident in the 6080 than the gain clone. This is a kind of quick and dirty shoot first, ask questions later experiment to see if I am anywhere remotely near the target with my "assumptions". Assumptions are, that the audible difference in sound of cables is caused significantly by an interaction between cable and amplifier, and that if you can hear something, you should be able to measure it, even though no one seems to have conclusively done it as of yet (to my knowledge). I know that my null has a frequency response problem, I need to try and address that first. It is quite likely the 6080 amplifiers are not working completely the same.

Thanks, It would be very easy to suggest that could be caused by the lower capacitance loading the non zero output impedance of the tube amp less. But I won't say that out loud.
It would be quite tempting to say we are looking at all that lovely euphonic even order distortion of an SE tube amp, but I didn't say that either, because it is to simpler explanation.
It would be nice to compare with the original recording.
It would give you an idea of what your setup is doing with it.
Can you post that snippet?

The most difficult thing in audio is trying to convince closed minded pseudo skeptics of anything, since their minds are already made up. As the guy in One Flew Over the Cuckoo’s Nest told the other inmates after he failed to lift the 300 lbs water cooler, well at least I tried.

People would generally be better off if they believed in too much rather than too little.
