UP-OCC solid core copper for speaker cable

After reading about all these expensive cables and their extravagant claims, I decided to source the same wire that goes into many of them.

I have my monoblocs underneath and therefore close to the speakers. I ordered 8 feet of 14awg UP-OCC wire (with PTFE insulation) online. It is quite springy so I clamped it gently to the bench and cut it into 4 equal lengths. Assembling it into 2 x 24" speaker cables took a few minutes. I kept it running in the same direction, just in case. Be careful to gently slice the insulation and not to scar the copper.

Anyway, the improvement in sound quality was of a high order. Large increases in speed and transparency, more air, better definition of instruments, less coloration, backing voices I never noticed before etc. The improvement in musicality was impressive.

I urge folks to try this before spending lots of money on speaker cables. I don't bother with connectors as I feel they are another item in the way but that's your call. The wire was $6 a foot.

Noromance - Good info. Thanks. I'm curious what speaker cable the DIY 14 awg replaced.
Ghosthouse, they replaced my other homemade cables made up of 14 gauge mains wire paralleled with a pair from CAT6 which replaced ClearDay solid silver cables.
I used some of that Neotech copper cable when rewiring the inside of a pair of Spendors and was also impressed. It isn't that expensive. Thanks for the idea, I may try it as speaker cable. Eliminating connectors when possible is certainly partly responsible for the sound quality I'm sure.
I am a distributor for Neotech once I realised how good they were compared to the Snake oil cable companies I was reselling. Profit margins are larger with the Snake oils stuff but I realised I was unhappy with them and I did not want my clients to feel the same. Now everything I sell is Neotech.
Audioquest, Furutech, Oyaide, MIT, PAD, Acoustic Zen, Harmonic Technology, Neotech, Wireworld are just a few companies that use UP-OCC Copper in their cables.
Would there be any improvement or difference by using the 12g versus the 14g you used?
Duvallite, 12 might give fuller bass. Certainly if you use big amps and like to go loud.
Hey guys - I'm looking at this Neotech stuff, especially factory terminated ICs (NEI-3005). Prices are VERY affordable. Wouldn't mind trying a 2 meter pair between preamp and mono blocks. BUT I think the stuff I'm seeing is stranded and not solid core?? See link. Do they make a terminated solid core- or even individually insulated stranded?, i.e. w/Teflon insulation??. Thanks in advance for your input on this.


Make your own! They are all stranded as the solid core is springy and unwieldy. Apparently the NEI 3002 is very good.
Awesome definition, I too do not like connectors but use them to sell completed cables only. I use multiple solid core UP-OCC copper wires for speakers and crossovers with FEP insulation and have found them to sonically destroy any other stranded cable I have ever used or installed for more than 25 years of speaker building and studio recording installations!
I have had great results with DIY solid core pure silver speaker wire in series with Furutech OCC. I also have several layers of Bybee purifiers in the mix.
Wow, I find it odd that a big improvement in sonics could be had by swapping out 24 inch long speaker cables. I'd suggest the the old DIY pair that noromance was using had developed some issues.

At any rate, I've done the exact same thing, only it was cheaper. Audioquest Type 4, buying the bulk variety for $5/ft not the $6 noromance paid. It's also less difficult to work with by the sound of it. I am using 12 foot lengths, and this is the cable that proved to me that cables do make a difference.

Yes good sonics can be had by not spending much. But you can get more improvements as you go up market. It's a question of priorities and money.
Interesting. For just the low frequency run in a bi-wire setup, I would think the 12 gauge would be better than the 14 gauge. Currently using an old set of Esoteric stranded 12 gauge wire for my low frequency run. How much difference will solid core versus stranded make on a low frequency connection?
Stranded cables have an effect on sound that I never would have believed until I swapped in the solid core Audioquest Type 4. By comparison, the sound became more focused and clear. Not that I thought I was lacking in that department, mind you. But it was quite easy to hear the difference. The result was that the imaging was superior.

Lower frequencies benefitted from this by sounding more accurate. My previous wire, a stranded 12 gauge didn't have any more bass even though the Type 4 is smaller by comparison. But I am not a bass head, for best bass one might want to go up to bigger sizes.
Runnin, the point of my exercise was to try the conductors that the more expensive brands use. In this case 7N PC-OCC copper. The improvement was definite. I don't believe the previous cables had issues in that their performance had deteriorated.
Check out this small manufacture, they use the same materials as the "big" boys without the big price tag. They only use 6N and 7N OCC silver or copper conductors.


Those do look interesting, but certainly much more expensive than the Neotech option posted above. In my case, I am only looking for cables for the low frequency run to my speakers. I can't see how the Audio Sensibility cables would be much better than the Neotech for a low frequency run.

I assume you do not mean a sub woofer connection, but the low frequency connection on a bi-wire configuration. If so, the quality of the cable is equally as important as the high frequency. The low end contains 70%+ of the music.

Did you check out the DIY parts section of the Audio Sensibility website, they carry Neotech, Furutech and a few others at very attractive prices.
Another very interesting company is Zenwave.

Due to a move and needing a longer run than my normal Teresonic cables, I bought enough of the 12 gauge Neotech cables for four long runs. Sounds very open. Bass is not quite as good as the Teresonic, and highs are not near as high, but a very nice cable.( actually a good thing, no brightness). No copper sound to the cables.

Very much considering the cables above.

Yes, the low frequency run to my bi-wireable speakers. Currently using an old set of Esoteric stranded wire.
What about Duelund silver wire in silk/oil? anyone think it's worth 25.00 per foot?
I’m bumping this article (if that is okay) as there are a lot of folks still blowing too much money on very expensive cables.
Here is a new link to the wire: http://www.partsconnexion.com/wire_hookup_neotech_cu_tef_sc.html
I found this on a cable review for Zenwave at AVREV.com and thought it would pertain here:

First let’s start with the basic raw materials that all cables require, the metal. According to Dave Cahoon, “Neotech supplies lots of cable manufacturers, the highest end...if you google UPOCC audio cables pretty much every cable company that comes up will be using Neotech's wire or completed cables. Neotech is the only company producing wire using the OCC patented process, Furukowa used to but stopped in 2013 in favor of a less costly process. Also, many cable companies built their reputation using Neotech wire, then switched to a cheaper alternative.”

So it seems you can buy Neotech for a pittance and terminate it your way, splurging on the terminations if desired, and have a pretty good cable by any measure.

Having said that, I'm not parting with my Zu Event speaker cables. :-)

All the best,

I need to get into the cable-building business. Folks still willing to blow huge money on cables instead of improvinv their source and other components.
Wow, a resurrection of an old thread.  Yes, I totally agree, Neotech cable is completely outstanding.  Though, it will be difficult to try to get into a cable building business.  A huge part of it is marketing and perception.  Also, resale value on boutique hand-made cables is going to be tough for audio end-users.  At this point, they are more likely to go to brand names because of both resale and perception.  It's a total misnomer because I can build a cable for less than $100 materials that will beat $2k cables.  My own opinion of course.


have you tried the neotech rectangular cable? the Amazon and the Sahara and if you have what is your opinion? there's a new company that has come into the audio industry called Infigo audio they're using ofc conductors in their wire and some of the reviews said it's better than OCC single Crystal I highly doubt it.


MIT does not use OCC single crystal wire sorry they use cheap ofc wire cuz I phoned them and asked them.


MIT is not very forth coming about their cable composition and geometry.  Call them again and ask them point blank….does the Taiwan Wan Lung factory provide MIT with their cables/wire?  Also, look at many reviews of MIT cables where they state 6N OOC copper used in the construction.  

@testpilot he is going to hijack this thread about his OCC expertise (to wit he has none)

I have Zafino OCC The Prima MKII OCC Speaker Cable 9AWG - ZavfinoUSA

Great cable and in my main system I have all Zafino OCC OCC Silver Dart - Graphene Dielectric Speaker Cable - ZavfinoUSA

Power, IC and Speaker.

An Interview with Steven Huang of Audio Sensibility - Dagogo

The rapid development of the electronics industry in Japan in the 1970’s led to the aggressive miniaturization of electronic components. This in turn drove the demand to draw wire of increasingly fine gauge. It became evident to Dr. Ohno that it would be necessary to develop metal materials with no casting defects or crystal grain boundaries to continue the miniaturization.

This became the motivation for his research which led to the patenting of the Ohno Continuous Casting process in 1986. Actually Dr. Ohno was granted five patents related to his continuous casting process between 1985 and 1981.

By using a heated mold with the temperature profile carefully selected, and drawing the material at a very slow rate it is possible to cause the solidification process to start from the inside-out resulting in the formation of very long crystals in the metal, rather than the many short crystals that form in conventional casting when the material cools from the outside-in.

Because of the requirement of very high purity metal (to prevent premature crystallization) and cast at very slow speeds, the cost of manufacture of OCC product is much more expensive than using conventional casting.

The OCC process was initially licensed to Furukawa Electric of Japan.

It soon became evident that the metallurgical properties of OCC copper were also advantageous for audio applications. The initial use of OCC copper wire in audio began in 1988 by a company called Furutech (no relation to Furukawa Electric) with Audioquest soon following in 1989 with its cables using Perfect Surface Copper (PSC).

The OCC process made a small fortune for Dr. Ohno, and in gratitude to his alma mater he made a generous research endowment to the University of Toronto in 1989.

University of Toronto OCC Research Lab

The UofT Department of Metallurgical Engineering established an OCC research lab in recognition of the donation. Today the Chiba Institute of Technology and University of Toronto remain the two leading OCC research centers in the world.

Dr. Ohno who is now in his mid eighties, is a Professor Emeritus at both Chiba and Toronto, and continues to keep in touch with researchers at the two institutions on a weekly basis. He remains in good health and was fortunately not affected by the recent earthquake in Japan.

Today there are three companies who cast OCC metals and an ever increasing number of audio companies using OCC copper and silver in their very best cables.


MIT does not use OCC single crystal wire I was on their website nor does it say anywhere that they use OCC single Crystal conductors, if they did it would be stated on their website they're probably using cheap junk ofc like transparent does and charge an arm and a leg for it, there's even something better out there now it's rectangular OCC single Crystal conductors and the Neotech is the only company that makes it, Superior to even the round OCC wire is check out their website and click on rectangular wire, the Amazon is there rectangular silver OCC wire and the Sahara is their rectangular copper OCC wire. I got the Sahara and I can tell you first hand it's much better than my round OCC speaker wire and interconnects and I was using the top stuff from Harmonic technology.


there's one thing Stephen Huang made a mistake in that interview that you put up, audioquest does not use OCC single crystal wire, I was on their website they use long grain Crystal which is an ofc wire and in their white paper it says that it has 300 Crystal barriers per foot nowhere on their website do they state that they're using OCC single Crystal conductors.


Can you provide a link for that on Amazon? I looked and couldn't find it. Thanks.


wp.neotechcables.com, then click on the three lines in the top right hand corner and then click on rectangular cables the Amazon is the silver rectangular OCC and the Sahara is the copper rectangular OCC wire, I got the Sahara speaker wire and interconnects and it's far superior to my round OCC from Harmonic technology and I was using their top of the line pro nine SE speaker wire and magic ll interconnects, this rectangular stuff is a real game changer, I talked to the distributor here in Canada for Neotech and he told me that one of his retailers put the Amazon up against an $18,000 wire that he was also selling and that the Amazon was better for half the price $9,000 US is still a lot of money but all I can tell you is this rectangular stuff is amazing,far superior than anything ofc at any price on the market that companies like transparent  are charging an arm and leg for crappy ofc conductors, just so you know Neotech supplies pretty much all the companies that are using OCC single crystal wire with their conductors.



if you want the retail prices I can give them to you because I have them.


not going to be a link on Amazon for these cables sorry that's the website if you can't get to it something's wrong with your computer

@havocman , He is labouring under the impression that the cable that you are talking about has been listed on *Amazon.com* and is asking for a link that doesn’t exist. 


unfortunately you're wrong about that maybe you should go to the website and check it out it shows pictures of the cables all the OCC cables are all solid core.


unfortunately you're wrong about that maybe you should go to the website and check it out it shows pictures of the cables all the OCC cables are all solid core.


Neotech, MIT, AQ etc., don’t make their own cables, they are source by companies that are licensed to produce OCC metals i.e. Furukawa,and Sumitomo out of Japan and Wan Lung out of Taiwan. The reason you don’t see manufactures quote the source of their cables is so they can apply their own unique marketing spin. Re-branding is not unique to audio cables.


you really should do your research better LOL, furukawa and sumitomo are no longer producing OCC and guess what Wan Lung is the parent company of Neotech LOL, so yes indeedy Neotech does make their own cables. and again you're wrong about another thing all the companies that are using OCC single crystal wire state it on their websites like zenwave, neotech, Harmonic technology, Acoustic Zen, nowhere on the audioquest site does it say that they're using OCC single Crystal, in fact in their white paper it states that they're using long grain Crystal which has 300 Crystal barriers per foot and then in their PSC+ it states that they're using a higher grade of copper doesn't say it's OCC single Crystal, there is the next level higher grade of long grain Crystal which only has 70 grains per foot so no one really knows what they're using in their PSC+because they don't State what they're using.



the rectangular silver and copper OCC will be much better than your Zu speaker cables, they're not cheap though but I got the Sahara which is the rectangular copper and it is superb much better than the round OCC.


I have more experience with OCC single crystal wire than you will ever have in your life, when Jim Wang was the owner of Harmonic technology I was repping for him here in the Vancouver area, and his niece now is running the company from Taiwan I believe, and the rectangular OCC single crystal wire is even superior to the round OCC, will beat cables costing double and they're rectangular silver wire the Amazon is not cheap it's about $9,000 US for two and a half meters.
