[HT cOz]

Introducing... cOz's Cables - I have a formula which I think combines great wire with decent plugs to make a very solid speaker cable.  I am offering these in limited quantities to Audiophiles who don't have a "real" speaker cable or want to try something different.  The cable pictured below is $75 .

This cable consists of 16 gauge X 4 wires that are wound by hand to create a very nice and unique speaker cable.  This version uses 80ft of Belkin PCOCC wire and is 8ft long.  Some of the features are:

•PCOCC copper conductors, which are essentially mono-crystal and 99.9999-percent oxygen-free in purity
•Unique multi-gauge, hybrid-conductor design
•Polyethylene dielectric material

Marketing information from the wire manufacturer.
The multi-core  multi-gauge, hybrid-conductor design, combines various conductor types and sizes based on their areas of best performance, to produce a cable that excels in every frequency range. Since frequencies travel at different depths through a conductor, they can become congested and interact with each other. Hybrid-conductor technology uses three distinctly different conductor types to handle the bass, midrange, and high frequencies. 

Additional info on PCOCC wire.

PCOCC has only 1 crystal and is also known as single crystal copper.  PCOCC is manufactured in Japan and there is only one casting machine in the world that makes true PCOCC.

The history

Standard copper is composed of thousands of individual grains of copper.  These grains can add an electrical barrier that is undesirable for high-end audio and video applications.

Normal, high purity copper has about 1500 grains in each foot (5000/m). The signal must cross the junctions between these grains 1500 times in order to travel through one foot of cable. These grain boundaries cause the same type of irritating distortion as current crossing from strand to strand.

In 1985, a method for the extrusion of a grain free copper wire was developed by Professor Ohno in Japan.  Known as The Ohno Continuous Casting Method, molten copper is forced out of the mold and very slowly draws the grain down the conductor’s length, creating a ‘single grain structure.

Thanks for looking at cOz’s Cables.
 
Standard Litz Braid with CMC Banana Plugs





Notice the 3 different size conductors and the Polyethelene dialectic around the primary center core wire.



Here is a close up of the new Furutech Spades after they have been crimped.  I wonder how you get such a great crimp?




The secret to a great crimp... Hydraulics and 12 tons of force at your fingertips. Hauahaha

What is the purpose of the winding and what benefit does this provide?

[Nick77]

Robert, those look great and affordable, how do they sound?

I feel it is primarily cosmetic.

My desire to build these cables comes from thinking that PCOCC wire itself is a great choice of conductor.  From the reading I've done, it has gained the reputation of being very neutral.  I also want to build a wire that a normal guy with family can afford to buy! Even at this price it is more than I want them to be, but I have learned that it is expensive to make cables.  It just takes way more time than you think it would.

This specific wire Belkin PCOCC has been reviewed on the internet.  It seems that people like it as long as you use multiple strands which is the approach that I have taken.  It is very hard to find these days and is out of production.  Also in my experience the 100ft rolls are suspect because they don't say PCOCC and are different in flexibility and in strand count.  I found this out the hard way   It is also encased in a jacket of PVC hell that takes a lot of time to cut off and discard. 

I will let others decide how they sound.  I am biased after spending hours to get a pair assembled.  These have the advantage of being from a known and trusted source Belkin and not being $1-$3 per foot of wire which is what you see for new stock PCOCC wire.  On the downside they do not use Teflon which would be preferred to polyethylene. 

I am also not a guru and often don't hear big differences and don't know if it is my system or me.  But I do believe in quality components and materials.

Neil "Walkern" bought the first pair maybe he will make some comments. 

Keith would you be interested in trying out a DIY Kit? 

Kind Regards,
Robert

A quality seam ripper can greatly reduce the time required to cut away the outer jacket with little chance of nicking wires.

I can speak to the overall sonic character of the cOz PCOCC speaker wire.  In a word, marvelous!  I've tried a modest variety of different speaker cables (including some DIY), none of which were crazy expensive, and these are by far the best I've heard.  Most recently I was using Nagy's cable, and the cOz wires have a more even overall balance, and eliminated a bit of grit or shrill character that I thought might be endemic to my system/room.  This speaker wire reminds me a LOT of a couple of different wires I've used in the past, namely Harmonic Tech Fantasy and Analysis Plus Oval 12.  The upper octaves are smooth, clean, and extended, and as noted earlier, lack any extra zip or sizzle.  The mids are fully fleshed out and beautifully balanced, with no emphasis in any particular range.  The bass is firm, tight, harmonically detailed and has excellent extension.  Soundstage is as wide and deep as my room (and a given recording) will allow, and individual instruments and voices are clearly delineated and 3 D (again, depending on the recording quality).

All in all I think this wire is a absolute steal, and a no-brainer for anyone who's looking for a beautifully balanced speaker wire at a bargain basement price.  I cannot vouch for the non-braided version as mine is braided, but I can't imagine that it sounds that different.

This is my new 6ft cable.  It offers the same great PCOCC wire and employs a Litz style twist.  This is available for immediate delivery and is priced at $60.  If you are using mediocre wire or are unsure about its pedigree you are in for a real treat!

In general, my wires will now feature this style of using only black shrink wrap for a cleaner look.  If you have other ideas let me know. 

Kind Regards,
Robert

I'm working on this pair of cables for a customer.  This is the new style of tight wind premium wire.  I have stoped using the red shrink wrap and have focused on a "cleaner" look.

Coz,

      The ad and website seems to have expired. How can I PM you? Thank you.

[HT cOz]

John you can send me a PM here on AudioCircle. I need to change those old links, thanks for the reminder.

Robert

[aerosong]

Robert,

           I am having a problem figuring out how to PM. Will get back with after I find out. Thank you.

Robert, have you measured the Capacitance, Inductance and Resistance?

I'd be curious to know since it's so tightly braided.

Thanks
Tuan

[HT cOz]

Tuan,

Let me first state that I am a hobbyist who has not performed any measurements.  The “secret” of my wire is to use quality materials along with a little spare time that I have before I go to sleep to create a reasonably priced/performing cable.  I do this while listening to my own system and feel the process of creating these cables is somewhat therapeutic.  The act of creating something with your hands is appealing to me. 

The construction of the wire uses 6 different materials and is itself very tightly wound.  How these different elements interact along with my construction styles (tight or loose) is unknown from a scientific perspective.    I am open to suggestions and learning.  However, I understand if others don’t want to share as they have potentially a lot of time and energy invested in their designs. 

While I reframe from comment about the sound of my wires, I will say that they have been well received by those who have tried them.  I would not sell them if I did not feel that I was offering a sound value proposition.  Above all else that has guided me to where this project is today.

Kind regards,
Robert

Robert, thanks for the reply.  I have heard from one user of your cables that they sound great!  So, looks like they are good.  I was just asking because I am looking into some DIY speaker cables as well, and I know how much time it takes to hand braid four wires of 16 gauge!  Kudos to you for doing it and at the prices you're charging, it's a steal for sure!  do you have a link to the cables?

That and they look very nice and well built!

Thanks

I'm the one that mentioned these to Tuan.  I've been running them for a week now, and they may be the best speaker cables I've heard with my setup.  They are causing me to sell my $400+ Morrow Audio SP4's, and I'm not missing my Reality Cable speaker cables either.

I plan to do a final evaluation and review after I receive my new interconnects (from Tuan) next week.  I want to provide some solid details to try and explain just how great I think these PCOCC speaker cables really are.

T I don't have a link other than what is here and in my galleries.  The amount of interest generated right here in AC is just about right for me.     It does take a lot of time to hand braid these wires.  In fact, I originally thought I could sell them for less money but no matter how good I become at putting them together it still takes many hours to complete a cable.

Kind regards,
Robert

Thanks for the kind words Terry,

I can't wait to hear how they work with your new interconnects from Tuan.  For the general audience, he has the loose braid or more traditional Litz braid. 

Happy Holidays,
Robert



...One more item to note.  I am now using these CMC Banana plugs




And these Furutech Spades




This will result in a small price increase.

Kind regards,
Robert

[saisunil]

Hi Robert ... I probably would like to take a plunge for spades on both ends ... what are the options for spades - or what is your experience ...

Thanks
