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…

Dear Steve,

 

Thank you very much for the quick response.

 

Another relevant question, if I have the choice to go with XLR or RCA interconnects within 2 meters (by buying or building custom-tailor (pre)amplifiers）, will Helix XLR be a better choice than RCA interconnect? You see, traditional wisdom usually says balance wire is better in trasmitting signal. However, Helix structure seems to greatly prevent noise pickup, as well as signal modulations between signal and return path, and therefore RCA interconnect might be very safe in this regard.

 

Thanks again.

@wyan001 - XLR or Single ended - that is the question.

Perhaps this is where synergy comes into play?

I know that some prefer the XLR verson, while others prefer the Single ended version. But they all state that the improvements of one over the other are miniscule.

Pehaps it is all down to the components in the system - they could have better circitry specific to one or the other.

It could depend on the quality of the XLR plugs that improves on the single ended cables

But - if there is lots of EMI/RFI in your "environment" then the XLR would be the way to go

The only real way to find out is to build both and try them.

Ufortunately I do not have XLR inputs on my amp so I am unable to compare them them.

I support Steve's statements.

Anything longer than 2m use XLR.

Find out, if your components both sides are fully balanced internally and not using a chip to only convert input/output signal from single ended to balanced.

However, I never experienced a negative effect from balanced cables, they always are at least "on par" with single ended.

Beside the wires you use, it is important to use good plugs and a good soldering technology with good solder. The wire must make direct contact with the solder pocket in the plug and use minimum amount of solder. The solder should only keep the wire in place and not "be" the conductor.

Therefore I do not use "lead-free" solder with no high silver content, as the conventional solders without lead melt at lower temperatures and "flows" better.

I use either Wondersolder or Cardas. Much preferred over all the lead free 4% silver solder from Mundorf, Furutech, etc.

Just found these Atlas XLR plugs with silver plated OCC Cooper pins - I would have to believe that is about as good as XLR's get.

https://www.analogueseduction.net/xlr-plugs-attenuators-and-adaptors/atlas-all-cu-xlr-plugs.html 

These AECO LR's would be a good second choice...

http://Pair Of AECO XLR Connectors AMI-1060S Silver Plated Copper Contacts

They would probably match the performance of the Harmony RCA's 

An FYI: A friend built extremely long 24 foot Single ended Helix cables and reported exceptional results, So they seem to work very well even at extreme lengths

Dear Steve and mawe,

Thank you for the inputs.

AECO also have all-sivler RCA plugs with similar structure to ETI/KLEi. Not sure how good it is compared to KLEi Absolute harmony.
