Directionality Explained

I have read it argued against by those who think they know
Here is proof
Paul Speltz Founder of ANTICABLES shares his thoughts about wire directionality. Dear Fellow Audiophiles, As an electronic engineer, I struggled years ago with the idea of wire being directional because it did not fit into any of the electrical models I had learned. It simply did not make sense to me that an alternating music signal should favor a direction in a conductor. One of the great things about our audio hobby is that we are able to hear things well before we can explain them; and just because we can’t explain something, doesn't mean that it is not real.

1. Would it be enough to be audible.
2. AC current simply flows with the charge being pushed by voltage it doesn't care about wire directionality. Flip the wire around and the current flows just the same if there was a difference it too would be easy to measure.

Have a look at Poynting vector.  (Not another wikipage :-) )

I've  read it. Doesn't change the way current flows. Electric current and electric energy where Poynting vector comes in are two different things. How you make current is move charges you do that by applying voltage.

If the direction of the wire caused a change in current it’s measurable.

If any part of an AC current is directional, then the AC signal itself must be directional - by definition. It’s like 2+2 = 4.

When a cable is connected from the amp to the speaker, energy flows from the amp to the speaker. That is at the amp end, the cable will experience more energy vs. the end closer to the speaker, hence by definition, an AC current is "asymmetric" due to the energy distribution.
