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.

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.

There are no absolutes in Audio, only preferences. I had a home audition of one of the companies speaker cables that uses rectangular copper. The company has been mentioned in this thread. I didn't like it in my system...they weren't as dimensional, detailed, and lacked the bass texture of my current speaker cables. 

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?

I have directly compared rectangular NEMOI-1220 and round NEI-1002 and preferred round wire. More dynamic, transparent and accurate.
Rectangular wire have limited top end for my taste. 
 

Amazon is a different stuff however there is few rectangular wires and one round wire in the boundle. 

"but you probably couldn't afford it anyways. LOL"

@havocman ,

So, what if he can't? I'm not saying hilde can't, but what if? Is that something for you to laugh at? Does it make you feel superior? More of a man to write that?

At those prices I freely admit I cannot afford such an extravagant expense.

Want to ridicule me, as well?

That one simple sentence speaks volumes about your character and the type of person you are.

@hilde45 you are correct and @tammyholt is now aware of the SPAMMING that @havocman is making in favor of Neotech and if you look at his history he is spamming every chance he gets. And he is abusive.

milimetr,

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

@havocman your post says it all. Now just go away. Reminds me of another guy @millercarbon.  No one is listening to your crap or your endorsements. 

Lo Life. 

 

thecarpathian,

maybe you should see his responses to me and why I'm ridiculing him I don't back down from idiots all I was doing was stating facts.

jerryg123,

gee I didn't know you were such a little baby reporting me, I'm not spamming I'm just stating facts, if you can't handle it go to another forum LOL, what a joke you are, go cry in the corner somewhere.

Unfortunately not. Only comparison two single stranded rectangular wires in PTFE insulation (NEMOI-1220) vs. two single strand round wires in PE insulation (NEI-1002). Rectangular wire was warmer sounding but with less top end extension  

If you are familiar with Amazon please let me know some clue about Amazon vs. NEI-1001 and Amazon vs. Sahara. Thank you.  

havocman, I have read his responses.

Your rebuttal was not a defense of your position or truth, it was the mocking of his perceived financial status. It was an attempt to belittle and demean by insinuating you’re somehow better because you can afford them. You could have stated what your perception of the truth is without your deliberate and admitted attempt at ridicule, but you didn’t.

And that is what speaks volumes about your character.

I also freely admit that I can be a colossal jerk, but I would never ridicule someone over their station in life.

There. I’ve had my say and I shall leave it at that.

 

 

Figured it out this @havocman man is none other than @urbie 

@tammyholt may want to just this down now.

dragon_vibe,

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.

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.

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.

@havocman 

With respect, my thread was about saving money using great quality Neotech wire and NOT about the really high priced cable you are endorsing. Please start your own thread on the subject. Thanks.

After various unsuccessful trials with various wire including Belden 9497 to connect my midrange and high frequencies horn drivers to their passive crossover, I've settled on Neotech UP-OCC solid core 16Ga with teflon insulation. The wire is quite rigid and not so practical but the sound is stunning, much better than anything else I've tried in that position, seemingly just passing the signal without adding or subtracting anything. Very highly recommended!
