Directional cables - what does that really mean?


Some (most) cables do sound differently depending on which end is connected to which component. It is asserted that the conductor grain orientation is determining the preferential current flow. That might well be, but in most (all) cases the audio signal is AC (electrons going back and forth in the cable), without a DC component to justify a directional flow. Wouldn't that mean that in the 1st order, a phase change should give the same effect as a cable flip?

I'm curious whether there is a different view on this that I have not considered yet.

You think a lot Geoffkait, but it is very interesting and I think true....The human apparatus it seems is also the key to anything in perceived phenomena, not only  electricity "per se"  and other materials factors that are necessary but not sufficient...

>>>>I would like to keep the two categories separate.

One category is for tweaks that operate by standard physics, which includes those affecting the electrical or audio signal anywhere in the system, acoustic waves in the room, vibration, RFI/EMI, even quantum mechanics devices like WA Quantum Chips I include here.

The second category I reserve for everything that affects the sound indirectly, usually by affecting the subconscious one way or the other. And by affecting our sensory perception of sound. When I use the term sensory perception of sound I equate that to hearing. There is no difference. This category includes most PWB Electronics products like Silver Rainbow Foil, the Red X Pen, Morphic Message Foils, etc. I also put in this category the Photos in the Freezer Tweak, my Clever Little Clock, my Teleportation Tweak, and the Black Cable Tie Tweak for Drain Pipes.

While some folks have insisted these tweaks in the second category MUST work by some known, conventional method, I assure you, gentle readers, they don’t. By the same token, and ironically, a lot of folks like to claim the tweaks in the first category, the relatively conventional tweaks, operate by psychology such as placebo effect or expectation bias. 
I understand why you want to keep these categories separate, it is not only legitimate but necessary to an analysis...

What about the type of dielectric, insulating material, used to cover the wire?
What happens to the sound of an audio system if cables that have been installed in an audio system for 100s, 1000s, of hours are flipped end for end?

With cheap cables that use stranded conductors and PVC insulation there’s a good chance you will not hear any differences. But how about good quality audio grade cables that use better dielectric insulating materials?

>>>>We are rather certain the problem is the wire, not the insulation because of the directionality of fuses.

>>>>>Directionality of wire doesn’t go away by breaking in the cable or fuse, even after 1,000s of hours of play. In fact, in the beginning HiFi Tuning claimed that no matter which way their fuse was inserted it would eventually break in to be the “correct direction.” They later recanted that claim. You can try this for any fuse, flipping it around after many years. You should be able to hear a difference.

>>>>I believe you will hear a difference even with inexpensive stranded cables and PVC insulation. Of course it helps to have a reasonably good system and a good listener To perform that experiment. As I said directionality is not related to the dielectric material. All this directionality stuff is not brand new. It’s been established over the course of many years. I realize it might be new to some.

Obviously shielded cables can also be directional if the shield is connected at one end only. But that is a separate issue from wire directionality.
