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.

testpilot,

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.

roxy54,

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

roxy54,

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.

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.

Roxy54,

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

noromance,

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.

testpilot,

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.

nonoise,

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.

Depends what length you want, 2 m is 4,200 US, 2.5 m is 4,800 US and if you need bi-wire it's $150 more. that's the manufacturer suggested retail price. and the silver is double that price. but from what I've been told that sounds even better, haven't heard it myself, I have the Sahara which is the rectangular copper and it sounds amazing, better than the round OCC single crystal wire.

jerryg123,

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.

ricred1,

yes you tried the one from zenwave, the Neotech reference cables are much better, the Amazon which is the silver rectangular OCC is $9,000 US for 2.5 m and the Sahara which is their copper rectangular OCC wire is 4,800 US and the geometry design is far superior to zenwave that makes a big difference. I have the Sahara speaker wire and interconnects and the grand power cables and they are far superior to all of my round OCC, zenwave is pretty good but you can't beat machine made cables for build quality and geometry design, you can't do that hand building unfortunately.

ricred1,

was that rectangular copper wire you tried OCC single Crystal copper or just rectangular ofc wire?

milimetr,

I haven't compared the two directly but I have talked to the distributor and he says that the Amazon is much better than the Sahara and the only use the round OCC in their interconnects not in the speaker wire, the speaker wire is all rectangular o c c wire and the distributor told me that one of the retailers in Quebec put the Amazon speaker wire up against an $18,000 wire and he said that the Amazon was better, makes sense because it's OCC single crystal wire as opposed to regular silver wire.

milimetr,

have you bothered to compare the Sahara or the Amazon that's the reference line? much better than the Nimoi-1220
