Directionality of wire
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.

I think it's funny how when Geoffkait doesn't like my posts he reports them.Yeah the forum police must be over him, then he is 75 going on 40 https://i.pinimg.com/736x/14/dd/c0/14ddc062b356122bdc338f9a7bdab4b3--history-images-hearing-aids.jpg Cheers George |
This is how bent you are Geoff, that is market place, feedback from 3 people I’ve purchased things off, it has nothing to do with the forums. You really are commitable, please, from the heart, admit yourself before something happens. Your getting on at 75, things go wrong inside the head we understand. Cheers George |
But my tweaks are not so mundane, they are not cheap parlor tricks. Really!!! your website indicates the total opposite. Now I’m laughing on the inside and outside. http://www.machinadynamica.com/ Cheers George |
"Lead, follow or get out of the way." You may call yourself a leader Geoff, but it’s of the electronically minded gullible, who believe in the same snake oil you peddle on your website. And that’s nothing to be proud of. http://www.machinadynamica.com/ And at 74! who are you trying to kid https://blog.medel.com/wp-content/uploads/2015/12/The-History-of-Hearing-Loss.jpg Cheers George |
These are great ones, and there's 3 pages of it. "I just perused this "Machina Dynamica" website. Wow. At least this guy has a relatively benign outlet for his mental illness." " I didn't know I was so popular. Whoa!" Geoff you really are certifiable! When is it going to be enough. Wish you a speedy recovery, you need to check yourself in. Cheers George |
geoffkait Now that is the pot calling the kettle black, Geoff you are really commit-able. You and your little avatars need to be locked up, I'm amazed the mods are letting you post. hifiman5 You need to know that even audio prototypes are done 100% using measurements, they're not concocted up in a blender. Cheers George |
Who said it acted like a diode?It’s the only technical non voodoo’ist explanation, if they (fuses or cables) are seen/heard to be directional. But I'm sure Geoff will pull another rabbit out of his hat. https://static.guim.co.uk/sys-images/Books/Pix/pictures/2009/12/16/1260957295386/Magician-pulling-a-rabbit-001.jpg Cheers George |
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. https://s-media-cache-ak0.pinimg.com/originals/81/6b/b2/816bb2ce803a876c3b46601f55730cac.jpg Cheers George |
What a load of c**p this thread has becomes,. As you asked before, SHUT IT DOWN fsonicsmith, before it degrades anymore if that's possible. Cheers George |
On Monday I am going to send a letter on my letterhead to the University of Virginia to check on your Linkdn claim of an aerospace degree from that institution and I will publish the results here. Best to you sir. For now.+1 fsonicsmith Got to give it to you Geoff, you got stamina. You've been laughed off many other tech forums, but on this one you've dug your heals in. Many would say you really are certifiable. Cheers George |
And as I said in an earlier post, IMO the least implausible explanation I have seen is the one stated by Audioquest. . The first part Al regarding the shield only connected at one end and which end to dump the RF to ground, is plausible, but I agree, the rest is not, and is just voodoo without any technical fact just to suck in the gullible here. Cheers George |
Can anyone tell me if this is accurate and has it been debunked as of late?Yes and no, the only wire that was, was LC-OFC (Linear Crystal- Oxygen free Copper) developed by Hitachi and Audio Technica some 25 years ago. It was heated up to a point where it crystallised the copper at the same time of being drawn into strands. Stereophile presented microscopic photos of the crystal structure and they were arrow shaped and lined up nose to tail, naturally the arrow head was pointed, and was considered as the flow direction. Sounded very good, BUT!!, trouble was that it was as fragile as cast-iron or glass. You couldn’t bend it much at all, if you did it cracked and cause micro air gaps between the crystals (sort of diode effect). Which resulted in worse sound than normal copper. Cheers George |
Sorry you feel that way. Not everything can be measured. 1: Every component you have has been designed using measurements. 2: Any changes to the sound the designer needed to make was done using measurements then listened to. 3: There is no voodoo in designing equipment by any designer of any component you have in your system. Cheers George |
jea48 Depends how good you are at hearing something that can be measured. If they are reversed and the shield is then dumping the RF noise at the source end, you "may" hear it as not as black a background as the right way around, I stress "may" depending on the amount of RF noise around your area. It’s always best with an interconnect that has only one end of it’s shield connected, that that end should go to the least sensitive component, not the most sensitive one. Cheers George |
don_c55711 posts07-30-2017 5:20amSingle ended interconnects are directional because they are grounded at the source end only, for lowest hum pickup and resulting low noise.+1 for Don, there’s a "technical" reason behind it, others are just making out something from nothing. Unless you have some of the 30 year old Audio Technica, Hitachi, Linear Crystal cable, (LC-OFC) of years gone by, which was "truly" crystallised lc-ofc copper "very fragile", trouble was if it was bent more than 30 degrees it cracked the crystal structure and sounded worse, because there was a diode effect at the crack points. http://www.hifido.co.jp/photo/10/586/58660/b.jpg With today’s quality RCA interconnects, it’s because most of them use 2 core inner cables "with an earth shield only connected at one end." This end should be leading to the poweramp end of signal direction, dumping any RF caught by the shield at the least sensitive end of the component lineup. Cheers George |
