So you think wire conductors in cables are directional? Think again...

If wire had directionality to audio signals somebody would already have invented a device to measure and quantify it! So where's this device?

It's called a vector network analyzer.

But hey, he's only a recording engineer working with Pink Floyd so what do they know?

 Really interesting article. Thanks for the link.

It's just not true...especially for AC. The AC current travels in both directions. Here's an easy explanation. Next time you have a burning question for a high-end cable manufacturer, present them with this:

Wrong.  AC current travels in one direction.  Look up Poynting vector.  We've been through this.  You're a bit late to the party.

The link you provided is like high-school level for those who can't get past first year college.

I've never bought into the directionality myth. Blind tests over the years indicate I cant tell the difference when the directions are reversed, no matter where the arrow is. I align the arrows just to assuage my OCD, but that's all.


The same with most cable quality. My 15' and 20' lengths of Canare 12 gauge speaker cable is indistinguishable from the 8 foot runs of Acoustic Zen Holograms I had before.

I especially found interesting in the link to the Physics Forum the idea that this myth is even more fantastic when it comes to digital signals.
