No one said it’s a good thing. Certainly not me. I would call it a subtle thing. Subtle but powerful. Just for the record this is about the fourth time I answered the same question. Or should I say non question. A Nothing Burger. 🍔
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.

geoffkait6,394 posts08-24-2017 5:00pmAs far as the directionality thread is concerned Al and Atmasphere have definitely not proved their points. Furthermore, it should be pointed out much of Al’s argument (as is often the case) is an Appeal to Authority, citing experts to support his argument. Even citing his own expertise, not to mention Atmasphere’s. That’s an appeal to authority. You know, a logical fallacy. Geez, all you would have to do to win any (rpt any) technical argument is say well, I found this guy so and so and he says such and such so I must be right.Geoff, Say what!! That has to the dumbest post of yours to date. Furthermore, it should be pointed out much of Al’s argument (as is often the case) is an Appeal to Authority, citing experts to support his argument.What planet are you from? Appeal to Authority??? You mean men like, Michael Farady ( Faraday's law of induction ) Joseph Henry (Inductance) James Clark Maxwell (Maxwell's equations) John Henry Poynting ( Poynting vector) Georg Ohm (Ohms Law) Alessandro Volta (Voltage) The list goes on and on. And yes, Ralph Morrison and Henry Ott among others. Whose examples do you follow when you present an argument or claim? Just your own educated opinion? Were you self taught, self educated? Start here. https://en.wikipedia.org/wiki/Poynting_vector You can have the last the word. I am not going to argue with you. |
All of those illustrious names are just names. You are a name dropper. Name dropping doesn’t win arguments. It’s an Appeal to Authority, a well-known logical fallacy. Especially in these audio controversies. You forgot Albert Einstein. Follow? You're not going to argue with me? Huh? You just did. Even though it was an illogical argument. |
@jea48 You’re joking, right? You really want me to post pics of me testing a piece of wire both ways with a DMM so you can see there’s no difference? Folks are selling this jazz like 9/11 truthers with rebranded accusations of cognitive dissonance, defying me to prove a negative. Skin effect is subtle, but that CAN be measured. Nobody here has cited a phenomenon that would explain a wire being directional because there isn’t one. If there was a way to build a directional wire, you can bet your ass that you could buy it by the mile. High speed data buses are forever plagued with termination challenges, specifically, preventing signal reflections from traveling backwards down the bus. If there was any way to form a directional trace or wire, buses for memory and parallel SCSI wouldn’t require meticulous termination. A big reason computer buses have gone serial hub based point-to-point is because terminating them is a hell of a lot easier and cheaper. Directionality is pure snake oil. Scour JEDEC and IEEE standards. You won’t find mention of any such phenomenon. |
