DIY Helix Geometry Cabling


Apologies for the delay, but it’s been very difficult to find a FREE platform to host the Helix DIY AIR Cable content that works with minimal hassle.

The cost of running the original web site was getting expensive, so I had to pull the plug on it

The new content detailed below consists of a series of PDF files that are derived from the web site content.

  • It takes a little time to load the PDF files - My apologies - but it is FREE smiley
  • HyperLinks within the test will not work - my apologies - but it is FREE smiley
  • You will see other files in the GitHub interface that were also derived from the Web Site, but they are not formatted correctly - my apologies - but it is FREEsmiley
  • Please use the files below - they will serve as the new pont of reference going forward yes

A special Thanks to Mikhail for hosting the PDF files on GitHub - very much appreciated

Please feel free to copy the PDF files for your own use or distribute to others - OR - you can just access the content from the links below.

Going forward...

  • the content will not be modified and serve as a base level design.
    • I have no plans to develop these cables any further, since the materials I identify appear to provide the optimum performance i.e. for my ears
    • If you want to run ideas by me then post them here
  • if you wish to share your own modifications and benefits then please post them here.yes
  • If you have any questions, then post them hereyes

Below are the sections from the web site that applies to the Helix DIY cable designs

@total111 - the answers to your question...

  • i preferred the sound of the silver plated stranded copper for speaker cables. Using OCC as the neutral sounded too clinical
  • 20 and 14 ft is too long for the Helix design. I did make a 12ft cable once
  • You can run the conductors in parallel, but keep them spaced about 10mm apart. To accomplish that you could sandwich the two wires between two pièces of brown paper parcel tape.

Using cables of different length normally impacts image and clarity.

  • This is generally due to the impact of the capacitance of the insulation.
  • If you adopt the "AIR" design of placing à bare solid  wire inside the teflon tube, for both signal and neutral, then because the wire has very little contact with the tube, there is very little capacitance, so the two cables should produce very good results

Hope that helps

@total111 , i use a twisted pair of wires for the signal and a larger gauge for the neutral e.g.

  • 2 x 17 gauge solid wire for the signal = 14 gauge
  • 1 x 12 gauge solid wire for the neutral OR
  • 1 x 10 gauge stranded wire for the neutral

@total111 The Links are to Solid Core PC Triple C.

The red sheath is 0.9mm and the black sheath Reference II is the 1.1mm.

For buying Solid Core, there only seems to be the option the buy a Branded Item.

Stranded PC Triple C Wire has been known to be sourced without a Brand Name attached to the sale item.
