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.
Here's something more down to earth although I am sure there'll be some who will have their own mental issues.  

Snake Oil and the Velocity of Propagation

Thanks a bunch, Roger, but we already knew the sky is blue. 
"...we already knew the sky is blue."
Not around here. It is grey.

What is the cake without chocolate?

If I can recommend Imperial torte or, as a second choice, Sacher torte.

(Don't be fooled, despite the name it is square.)
Actually the sky is black. The blue color comes from the sun. But oh! wait. The color of the sun is not blue. Our sun is actually classified as "yellow" due to its temperature. Some people think our sun is actually more "green" than "yellow". Some would argue that our sun color is "white" since it has a wide range of color from red to blue.

Damn I am an expert of the Sun thanks to online :-)
