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.

There are two things that are in favor of directional argument which I already posted in the past.

1. If you got L3>L2>L1, then the impedance may not be the same one direction vs. the other.

2. An AC current is directional even if it's an alternating current.

Also I’ve seen the impedance of the cable changes if you flex them in one way vs. another, that is its impedance changes due to physical orientation. But I have to admit that this is probably caused by the change in the dielectric insulation and probably not because of the wire.  The wire "directionality" in coupled to the dielectric material may play a role.

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.
