Another look at directionality in cables

A friend of mine and myself were discussing this subject. It was brought up, if a cable is directional, why would both arrows on the positive and negative point the same direction. It appeared that, for example, that the positive would point from the amp to the speaker and the negative should point from the speaker to the amp ( even though there is no positive and negative using AC-reference only for phasing). This way, since the signal alternates, that at least the signal would be going back and forth on the wire in the same direction at any given time(maybe.) I have discussed with engineers about wire and most agree that it does have a (marginally better at best) flow in one direction depending on frequency and wire structure. All agreed it was not significant.
My friend tried it and said he got better results with one wire going one way and the other reversed---go figure. Of course with some wire, you do not have this option with it.
Opinions?

Power is transfered in one direction from source to load

voltage & current are certainly alternating but this is not the issue & only serves to confuse

certain cables with certain equipment makes this phenomenon much more obviously understandable when the effects can be heard firsthand, in some other situations you'll never know the difference

I did that once unknowingly & about went nuts trying to figure out what was wrong with the highs. Tried all kinds of things to fix it & had finally given up. Then one day when I was fooling around back there I discovered my error, & much to my surprise the grainy hf's normalized when the cables were corrected. My own blind test, & I didn't even realize that I'd done it. Proved it to me...
