Directionality of wire

I am a fan of Chris Sommovigo's Black Cat and Airwave interconnects. I hope he does not mind me quoting him or naming him on this subject, but Chris does not mark directionality of his IC's. I recently wrote him on the subject and he responded that absent shunting off to ground/dialectric designs, the idea of wire directionality is a complete myth. Same with resistors and fuses. My hunch is that 95% of IC "manufacturers", particularly the one man operations of under $500 IC's mark directionality because they think it lends the appearance of technical sophistication and legitimacy. But even among the "big boys", the myth gets thrown around like so much accepted common knowledge. Thoughts? Someone care to educate me on how a simple IC or PC or speaker cable or fuse without a special shunting scheme can possibly have directionality? It was this comment by Stephen Mejias (then of Audioquest and in the context of Herb Reichert's review of the AQ Niagra 1000) that prompts my question;

Thank you for the excellent question. AudioQuest provided an NRG-10 AC cable for the evaluation. Like all AudioQuest cables, our AC cables use solid conductors that are carefully controlled for low-noise directionality. We see this as a benefit for all applications -- one that becomes especially important when discussing our Niagara units. Because our AC cables use conductors that have been properly controlled for low-noise directionality, they complement the Niagara System’s patented Ground-Noise Dissipation Technology. Other AC cables would work, but may or may not allow the Niagara to reach its full potential. If you'd like more information on our use of directionality to minimize the harmful effects of high-frequency noise, please visit http://www.audioquest.com/directionality-its-all-about-noise/ or the Niagara 1000's owner's manual (available on our website).

Thanks again.

@nonoise   I'm sorry.  I was not clear enough.  I was not referring to you as the dictator, rather a frequent "authority", who pontificates authoritarian views here with disturbing frequency.

All the best!

@nonoise  Cincinnatus was a direct role model for George Washington.  Indeed, a statue was made of Washington as a Cincinnatus figure!  Plow and all.  Washington was the quintessential public servant ala Cincinnatus.

Your introduction of history into this thread is welcome as it lends perspective on the present.

@hifiman5 , I didn't take your remark as "me" being a dictator at all. 
No worries here, but I don't see myself as an authority on anything, truth be told. Just another one of many with an opinion, and hopefully a funny one at that. 😇

As for Cincinnatus being a role model for Washington, I can only wish that were a requirement for all succeeding presidents, written on some dusty old parchment, attached to the Constitution. 

All the best,
Nonoise

So the whole idea of "energy" traveling outside the wire is pretty preposterous.
If that was true then the means we have for determining whether or not a wire is hot by placing a device near them would not work, like those little gizmos that you put near an AC line that beep when the line is hot. If all energy was contained inside the wire then transformers would not work. Radios would not exist. etcetera

I never said all the "energy" was traveling inside the wire. I posting earlier that components of the electromagnetic wave - such as the induced magnetic field B - are obviously outside the wire. Even the mathematical paper someone linked on this thread (in a failed attempt to prove the energy traveled outside the wire) described "energy" inside the wire. Please read what I say more carefully so as not to put words in my mouth. Obviously radio transmission is an entirely different subject. Like radio communications via satellite, which I also recently decribed. I.e., photons. You know, EIRP.

have a nice day
