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.

At least it gives me something to chew on while I am sipping Cabernet Sauvignon lols.
Going beyond directional cables for just a sec, how many other things in the audio system should be controlled for directionality? Even pseudo skeptics should feel free to join in. 🤔
If importance of cable directionality is anything to go by.....none.

I wish I didn’t believe in cable directionality but its real in some, but not all, instances. I have refrained from posting on this topic because I don’t want to distract the skeptics from their planning phases  of storming Area 51.

other things that benefit from directionality:
1) swallowing food is better in one direction than the other
2) my experiments indicate that, in general, speakers tend to sound better facing the listener than otherwise
3) incoming power, as opposed to outgoing, tends to positively affect sound reproduction
4) I also prefer incoming fund flows to outgoing

peace...
