Duelund conversion to DIY Helix Geometry Cabling

I have been an avid user of the Duelund cabling for over two years now and have used them exclusively in my system with great results. I have built many for friends and have used a full loom of interconnects, speaker cables, power cords and an extensive wiring modification for a previously owned balanced power conditioner utilizing Duelund 600V PolyCast wiring which was transformative. My cabling desires can be a little addictive as I have owned and evaluated 40+ brands of cabling costing more than an entire stereo system!

Over the past six months I stumbled upon a thread here on Audiogon in regards to a Helix designed cabling and as you probably already know, I just had to look a little deeper into this cable design…After a month of studying and sourcing parts, I decided to reach out to the designer/architect, Williewonka who gave more insights and philosophy on how the cable came into existence.

That conversation got the ball rolling in converting one of my KLE Duelund interconnects to Steve’s Helix designed which only entailed replacing the neutral with a Mil-Spec 16 AWG silver-plated copper wire with the neural wire being 3 times longer than the signal wire and of course the “Coiling” of the neutral wire : )

After the modification was complete, I was not sure what to expect from the Helix cabling but I was quite shocked with the results with “ZERO” burn-in time…The sound stage became much wider/deeper with a much tighter/focused image and clarity/transparency is like nothing I have ever heard in any cabling regardless of cost. In fact, I just sold a full loom of a commercially designed Helix Cable that’s renowned around the world and has more direct sale than any cable manufacturer; these $200 DIY Helix Cables walked all over them…

I believe you will hear the same results as I have and have heard back from friends who have already modified their Duelunds with the same results; WOW! Remember the cables will need 200+ hours to burn-in and settle into your system. My system is now 90% DIY Helix to include IC, SC, PC and Coax with each cabling adding its beauty of an organic and natural presentation that draws you into the fabric of the music.

You can tailor the sound of your cables using Duelund, Mundorf silver/1% gold, the outstanding Vh Audio OCC Solid Copper or Silver with Airlok Insulation or your favorite wiring and you can change it at any time…

PC OCC (Purity Copper - Ohno Continuous Casting) is a Japanese design for a Wire and has been produced under a Patent and known as the name PC OCC.
This Wire is no longer produced by Furukawa and is maily offered by Furutech who purchsed most of the final stock.

UP OCC ( Ultra Pure - Ohno Continiuous Casting )
Is made under the same Patent but is from another juristiction as the Furukawa produced Cable.
UP-OCC has not been stopped as a manufactured wire, but has been upgraded as a design to be UP-OCC a  (Alpha)
This is a cryogenic treated version that Furutech have become involved with.

Furukawa today offer PC Triple C as the replacement wire for PC OCC and the crystal structure is different in the Triple C.
It seems to work well wit Nano Treatment as to Cryo Treatment.

D.U.C.C
Is the purist of the modern wires, it is very different in the crystal structure to PC OCC, through the Crystal alignment, which are even more aligned by a In House Treatment which is referred to as 'Stress Free'

The last of the five Ohno Continuous Casting patents was issued in 1991, so these patents are all expired and anyone can make this product without license. I don't know whether there are trademarks on the name though, which could survive well past the patents. 

The OCC process is fairly costly, particularly with higher gauge materials, since the length of wire that can be produced at one time is much shorter. It's hard to believe that all the product we see on the market that claims to be OCC, really is. I don't know how this could be verified, other than by the reputation of the producer.

UPDATE: regarding  Balanced Symetrical Amplifiers

A few weeks ago I posted some updates to my web site identifying some amps that would not sound their best if a regular Helix cable were used with them.

I have now posted an adaption to the helix design that should work very well with these amps

Please see this link for the details if interested
http://www.image99.net/blog/files/b4dd81de6d4c72aa5052e5692987a506-81.html.

This approach could be used with amps that employ a single ended design also if desired...
  • takes a bit more fabrication effort
  • but the wire may end up costing a little less
At present, this is just in the design stage, but a fellow Agoner will be trying this approach to see how it performs compared to a conventional speaker cable

Stay tuned :-)

Regards - Steve

The name of OCC is given the name of the Professor Atsumi Ohno who discovered the Manufacture Process, where a Long Crystal was produced with the Wire.

I would assume if a Wire is produced with a Crystal Structure that is within the dimension that is outlined in the criteria for a Wire to be called OCC, there might be some ground for a challenge to be made.

There might be Wires Produced today that have a Long Crystal that is outside of the original OCC Specification, but when compared to a OFC Crystal qualifies as a comparison for it to be to be called OCC without too much risk of being challenged, especially if produced outside of the juristiction of the Patents.

Out of Interest, are the Five Patents known to have a end product of a produced wire ? and I wonder who the additional producers might have been.

So I just bought a newly-made helix power cable from one of the guys on Tube Owners Facebook group (I think he's on this forum too) for my Cayin HA-300. Previous power cable is a Morrow Audio MAP3.

It seems to be fine for the last 2 days, but today I'm hearing a strange high-pitch static hum, kind of a buzz hum at times when no music is playing. It's not affecting my VU meter, nor does it change in volume or goes away when I put the volume down to zero. I haven't heard this before, especially on my previous cable. What can be causing this?
More to discover
