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.

It’s a shame Bob didn’t live long enough to see the HiFi Tuning data sheets on fuse directionality. Everyone talks about wire directionality but no one does anything about it. If only Bob and Curl had experimented with fuse direction back then they would have known the answer.

Question to self: can’t anyone measure the resistance (conductivity) of a cable or wire or fuse in both directions? Duh! Why don’t they? They’d rather fight than switch. The pathological skeptics seem to be getting up a full head of steam. Think I'll take cover.

but nobody has ever measured directional wire or fuses. I'd say that's because it doesn't exist. Pathological denial of the existence of a phenomenon beyond measurement? I guess if rational thought is pathological, I'm guilty.
+1, it's all voodoo, led by you know who.

Huh.... Can’t measure it? That’s the problem with things that exist purely in your head, isn’t it? I mean, we live in a say when we can study the most microscopic, nuanced phenomenon in the universe with obscene precision, but nobody has ever measured directional wire or fuses. I’d say that’s because it doesn’t exist. Pathological denial of the existence of a phenomenon beyond measurement? I guess if rational thought is pathological, I’m guilty.

What a drama queen! You just can’t read. Directionality has already been measured. If you would do your homework you’d know that. What I meant was, if you would slow down and use your ears instead of your mouth, is that you naysayers, specifically, won’t (rpt won't) measure it. You know, use a volt ohm meter and measure the resistance. Then you would know. Follow? But, no you pathological naysayers would rather keep yakking. Is that rational?
