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…

I have always connected the “spacer-wire” at the mains plugs side together with the GND wire.
If there is a EM field inducted from the “life” conductor to the spacer, this will be fed to ground.

Main reasons I do this are, more equal spacing between life and neutral and it gives the whole construction a more solid fit. The Jantzen wire for neutral is not as easy to work with as if it would be with a solid core wire.

No, in this construction I do not cover the life wire with anything else.

I have made more than a dozen different Helix PCs with different wires and they all sound slightly different.
This Design is with my ears and my equipment the best compromise in terms of “sound” and “construction”. 
On the “air” (wire without insulation) design and on other designs I had used  2 Teflon tubes (6mm and 12mm) to create a kind of “spacer” to keep the neutral away from the life conductors.
I think the coiled GND wire is at least equal and easier and more cost effective.

I use a 3:1 ratio.

I used different plugs, and these “sound” more different, than some of the different constructions.
The SonarQuests silver plated are very open. On some applications I prefer the Furutech FI-15 (G) IEC connector, as it is easier to work with and has a more “solid” sound signature. And for Schuko plugs I used either SonarQuest, Wattgate or Hifituning. Later 2 are easier to work with. 
A jump back in time to the last days of 2020..

@divertiti asked for directions on how to convert an already finished cable from RCA to XLR.

@grannyring answered in a way that could be an object for discussion. As I’m about to embark on the exact same journey, I would be very pleased, if someone could confirm my understanding on how a Helix Image with XLR termination would be made.

As I understand the layout from the answering of @grannyring there should be 2•18GA for positive +ve and 2•18GA for the negative -ve and a double helix consisting of 2•16GA for ground.
Ratio should be 4-4,5.

Am I on track here with this understanding or have I totally missed out?
@provst - I just looked back at the @grannyring post you mentioned and your understanding is correct.

But saw no mention of the ratio in that post, so I think the ratio of the Helix coil should remain 3:1 Neutral to signal

I generally reserve a higher ratio of 4:1 for Analogue Interconnects that employed from a Turntable to the Phono Stage to offer a little better shielding capability to the extremely small signals at play.

The signals in interconnects between components are much more robust and not amplified to the same degree. 

This is the Schroeder Double Shotgun approach, which is proving to offer the best performance.

Hope that helps - Steve
The helix ground on your xlr is never a twisted pair, but always a coiled helix. It is not a huge sonic degrade if you just use one conductor as the helix. However, two sound a tad better.

If using two wires on the helix, then just coil them up side by side on your drill at the same time.  Very easy to do.  I have been able to uncoil the TFA wire once coiled.  Took my time and did a good job of getting it straight again.

I would use a 4-4.5 to 1 ratio on the helix to pin 2&3 conductors if just using one conductor.
Hi Steve,
Thank you so much for a swift response.
The above section is taken from @grannyring answering in more detail at 12-30-2020 1:45pm.
Now - upon reading your explanation and recommendation for interconnects, and re-reading the answer from @grannyring I guess you are still aligned. As I now see it, the ratio of 4 - 4,5 is in case you are using only one helix for the ground. If using two helix for ground, ratio should be 3:1. Is this correct?
@provst - Since the Double Shotgun approach will provide the very best sound quality I would use a double helix with a ratio of 3:1
