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…

@marcus87 - RE:
  I have some questions left before placing my order and would highly appreciate your kind answers:

1. Should I handle the 2 unstripped Neotech wires similar to stripped ones (twisted closely every inch)?
2. Should the twisted live wire be covered in cotton? If so, which diameter is appropriate for 2x16AWG?
3. The ratio for neutral and ground to live is 4:1, correct?
4. Covering the final cable in a cotton or nylon sleeve should be avoided in order to get the best performance, correct?
5. Any thoughts on helix DC cables? Or what is your favorite DC cable recipe to pair with the helix AC PCs?
  1. Relax the twist a little - one twist every 2"
  2. 2 x 16 can use the 1/8" cotton sleeve
  3. a ratio of 2.5 - 3.0 to 1 is better

#4 - To SLEEVE or NOT - I prefer not to use any sleeve, but I can also see the need for a sleeve.
- does cotton sleeve impact the sound?
- maybe, very slightly, but you would have to listen very intently.
- Other people found the the nylon I had used previously did impact sound

#5 - DC Cables - this is uncharted territory and I have no DC supplies to test my theories.
Because DC does not alternate then there should be no noise generated within the cables
BUT the current certainly fluctuates as the signal draws different levels of current, which could in turn cause very slight voltage fluctuations and those could impact sound quality.

But you might want to consider using a better quatity wire for DC power cords
  • Use 1 x 18 up-OCC gauge wire inside a teflon tube for the +ve wire
  • and use a 1 x 16 gauge Silver plated Mil-spec wire - about 1.5 times the length of the signal wire wrapped around the teflon tube in a more "stretched out" Helix coil
Hope that helps - Steve

""RE: RCA to XLR...

OK - so there is no real great solution for this setup. You can create a cable with RCA at one end and XLR at the other. The Helix geometry is probably one of the better geometries for this because of the lack of noise in the cable.
On the XLR end
- Pin #1 would connect the neutral coil and 
- Pin #2 would connect the signal wire
- pin #3 left unconnected

Hope that answers your questions

Regards - Steve""

I have always connected pin 3 as well to the pin 1 in the XLR connector.
Both will work, have a try, what sounds best to your equipement.

@ marcus87

living in Europe, I have made my low powered pc's with 2x 16 AWG OCC Neo unstriped like this:

Life = 2x 16 AWG OCC Neo in PTFE twisted 1x every inch clockwise.

Spacer = 1 x 15 AWG (1,5sqmm) solid core groundwire (green-yellow) from home depot with PVC insulation (cheap) coiled on a 6mm dia rod clockwise ratio 3,5:1. Slide the life wire into that coil. This is only connected to wall plug, as ist acts purely as a spacer.

Neutral (and grd if needed) = coiled anti-clockwise on a 12mm rod. I used Jantzen silver plated 4N copper in PTFE as well.
Slide it over the Life/GND construction.
This way, the space between life and neutral wire is very even.

A low cost version I have tested as well (use it on my diy power supply for 5V DC for my amazon fire stick and on the 5V DC for my ethernet/fibre-optic converters).

Instead of the expansive OCC Neo wire I have used the Jantzen 6N OFC copper speaker cable (2 x 1,0sqmm / 17 AWG) as live conductor.
Coiled a 1,5sqmm GND wire as spacer (as above) and the Jantzen silver platted copper 1,3sqmm x 2 as neutral.
Note: The Jantzen speaker cable is only approved for max 80 V, so you can not use it as a power cord when connecting  the 2 internal wires one to life and one to neutral !!!

It sounds not quite as open as the OCC Neo, more pleasing which can be a good thing in some applications.

Thanks a lot @williewonka for your reply!

@mawe I am from Europe as well... Going to order at audiophonics.

Spacer = 1 x 15 AWG (1,5sqmm) solid core groundwire (green-yellow) from home depot with PVC insulation (cheap) coiled on a 6mm dia rod clockwise ratio 3,5:1. Slide the life wire into that coil. This is only connected to wall plug, as ist acts purely as a spacer.
So if I understand correctly, you use the 15AWG gnd wire only as a spacer between live and neutral. Shouldn't this mean that you are NOT connecting it to any plug?

Do you use a cotton sleeve on the live wire on top?

This concept sounds interesting, have you compared it to the original design? What benefits does it bring? Better handling/stability of the cord? Better sonics?

Do you use a 2.5 to 3:1 ratio for neutral to live as well?

Cheers,
Markus
