I think we might very well have just witnessed the auspicious arrival of a brand new Juror #3 on the set of 12 Angry Men. Welcome aboard, soldier!
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.

kosst_amojanBack at you. Show me any credible test data that says it doesn’t exist. You can’t, can you? And why can’t you tell me why it would be a good thing even if it did exist? I’ve asked twice now.Just a guess it was discovered by accident many years ago. Some one discovered directionality by listening to a cable they had built. ( I never found a cheap IC that uses stranded wire and PVC insulation that I could hear any difference if the ICs were reversed. I tried it about 16, 18, years ago.) I first leaned about wire/cable directionality when my son bought some solid core copper silver plated "Wonder Wire" that had/has a Teflon dielectric, insulation, from Micheal Percy. Just going from memory it was around the late 1990s early 2000. It could have been earlier, I just don’t remember for sure. Micheal marked the end of the wire as it came off the spool with a piece of masking tape. And yes the wire was directional. As for a good thing??? Well, I guess if YOU can/could hear the difference and one direction sounded slightly better than the other direction which way would you install the ICs or speaker cable in your audio system? I mean why does anybody use anything other than cheapo $2 or $5 ICs in their audio system? Back in the 1970s that’s what I used. For what it’s worth The Audioquest solid core silver wire ICs and speaker cables I own sound best hooked up in the direction of the arrows on the cables. The Clear Day solid core silver wire ICs I borrowed from my son for at least a month or so again sounded best, to my ears and my son’s ears, in the direction of the arrows on the cable. Take the time and read this post where John Curl tested ICs just to prove they do improve with break-in, burn-in time. It’s not as simple a matter as you will discover. Was John’s testing method accurate or flawed. How about the other guy’s test proving ICs SQ do not improve with break-in time. Was his testing with a multi-meter correct? https://www.audioasylum.com/audio/cables/messages/4/42469.html AA threads are a little hard to follow at first.

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. |
