Images: Viborg Milled Aluminum Gold AC connectors (gold plated brass contacts; polycarbonate body; milled aluminum shell with 4-point set screw strain relief mechanism featuring flexible silicone grip; includes torque wrench).
Finally a low-cost AC connector set that gets it right. What's not to like about the well-engineered design other than it features brass base metal contacts rather than phosphor bronze or copper contacts. This is decidedly the best-sounding, low-cost Audio Grade AC connector set, IME. I've researched the brand, and have a comparative evaluation vs. other Audio Grade AC connectors in the works that I'll post in Cable Asylum at some point, including a surprising winner vs. another set with copper base metal contacts.
$25 + free shipping must be true wholesale value, at least. Worthy of a substantially higher price point based on build-quality and audiophile performance level, IME.
the body, set screws, clamping,look unsuspiciously like Gaofei. I suppose these are next gen?
Other than EIZZ, most brand names like Gaofei, Copper Colour, Aucharm, Sonar Quest, MS Audio, Valab, Vanguard, Viborg, et al. seem to be marketing ploys, so any real design factors and credibility of any sort is simply not the same as reputable Japanese, North American, and European gear. There's plenty of cheap junk to wade through, in order to find a few gems.
In the case of Viborg, there is a Chinese manufacturer of high-quality stainless steel plumbing devices named Viborg, and adding 2 + 2 I'm thinking Viborg might be the actual manufacturer of a number of Chinese audio products. It's mystery enough when it comes to Japanese gear, while Chinese gear is often unfathomable.
There might be a "next generation" aspect to more recent products, since plenty of intellectual property rights infringements and reverse engineering has taken place from an industrial manufacturing perspective. The first hurdle the Chinese needed to jump-over is to not just make something "look like" an audiophile product, but to deliver the audiophile goods, at low-cost or an actual-equal to name brand product price points.
Here's another moderate-cost level set of Viborg AC connectors featuring a high-quality carbon fiber layer inlay AC connector shell for energy dissipating purposes. Looks to be the same body/contacts as the Viborg milled aluminum shell AC connector set. Looking forward to re-terminating another power cord, currently terminated with gold plated Audio Grade AC connectors with this relatively inexpensive $40 set of HQ AC connectors.
What about all the other Viborgs that are cheaper and have the red copper and red copper gold plated conductors?.......they have plastic housings. Seems you would want the better conductors....or does the aluminum make all the difference? I would want to listen to all of them and also listen to them without the sleeves on any of them and just wrap the AC screws with electrical tape. You could always make your own copper shield, if you wanted.
Virtually all inexpensive Chinese AC connectors feature brass base metal contacts. Any mention about copper or "red copper" tends to be misinformation or has to do with a copper plated brass base metal, which is a very unappealing plating concept with dubious sonic benefits; I have no wish to explore such a thing.
I believe the massive milled aluminum shell with 4-point silicone grip is the key to better performance, since it provides outstanding rigidity, and I'm sure the 4-point silicone grip also provides a high-level of resonance control vs. a typical flimsy plastic clamping mechanism. If a plastic-shelled Furutech or Oyaide AC connector body could fit into the milled aluminum shell (they don't fit), I'm certain a level of improvement would be found.
As for shielding, I don't think it's the primary benefit of the metal shell; it's the rigidity that matters the most. A possibility to ponder is that the aluminum shell may affect eddy currents in a manner that might dissipate stray electrical fields to a degree, but that's just postulation on my part. If anything, a carbon fiber sheath or perhaps ERS sheet material wrapped around the outside of the connector barrel for energy dissipation might be of benefit rather than EMI/RFI shielding purposes.
I've ordered another Viborg AC connector set that features a milled aluminum shell with carbon fiber inlay that's similar to an Acrolink AC connector design. It likely features the same polycarbonate body with gold plated brass contacts as this model features. I'll also include an evaluation of that AC connector set when I post a report in Cable Asylum.
of any AC connector that relies on conductive set screws to secure the cable. A clamp is much safer. Could something really bad happen? You bet. Will it happen? Probably not, but I would not want to be the one to find out.
berate is 8 and benign is 9
I have in such instances used light gauge copper sheet to wrap the strands and make a solid air tight connection, which is really what you are after.
If not for the fact that the AC connector design features a substantially-thick silicone grip that protects a power cord jacket from the 4-point metal set screws, I would agree with you.
Looking forward to your comparisons when you have time to post them.
Cheap knockoff or not?......
Thank you Duster, as you are adventurous enough to at least seek out options on these and other types of connectors and Plugs on the behalf of those of us whom are more prone to think outside the box then others. I'd add that over the years since I first met you back in 2004, you've taught me a great deal on how to select the right types of RCA | Bindung Post | AC | IEC Connectors and plugs based upon their plating, as it related to voicing " my system to taste " and have in every single case been spot on as far as your recommendations.....
Even in assisting me in selecting the right brand of bulk cabling to use for power cords, and while I've gone in different directions from time to time, I've always viewed your recommendations as nothing less then solid....
Thanks for the kind words, email@example.com.
Much deserved......., and above all very true.
Is that an audio system of yours? It looks to be excellent.
No it isn't, as I never learned to post photos of my system components as you've so nicely done in the inmate systems section......, I merely search the web for what I view as interesting systems or components and save them to my photo gallery to post said images as I respond to add a little bit of character.
Very nice idea, thank you.
I post a lot of found-images from the web, too.
And no matter what!, keep bringing us these great tweak concepts. If you don't, nobody else will.....
This must be the cheap Chinese knock off. (tongue in cheek)
