Directional?

Without intentionally wanting or meaning to plagiarize @nonoise, "no, not again".

I mark the direction of the cables I build for one reason. So once burned in if the owner pulls them off and back on he can be sure he is putting them back  in the same direction the signal originally burned in the cable. 

"Directionality and Burn-in" Let me put on my Tin Foil hat and think about it!

Uh, guys, no one is disputing that shielded cables are (usually) directional. So the question is really about, or should be about, non-shielded cables. Let me answer a question with a question. Why do many BIG audiophile cable manufacturers like Audioquest control directionality of their all their cables, including non shielded cables, power cords and HDMI cables? Anti Cables controls directionality and they don’t have shields or even jackets. Hel-loo!! Hint: it’s probably not (rpt not) to drum up business by appealing to audiophiles’ innate curiosity or that they think the terminology “directionality” is cool.

note: graphene is more effective than tin (aluminum) so a graphene hat will (theoretically) be more effective, no?

Thanks, all -- excellent explanation. I appreciate your willingness to share your knowledge.
