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

  • Please Do Not - use private messaging to contact me - Thanksyes
  • The PM Function now asks me to enter my Credit Card Info and I am very guarded about that info, so it will not allow me to respond to PM Requests
  • Post your questions here with @williewonka somewhere in the text and I will get an email identifying the posting, which I will then reply too

Many Thanks

@newkey1941 - did I respond to your last PM post? (see post above this one)

If not, let me know and I will post a response here.

Cheers

PM seems to no longer be available, and am not sure if I can recall the question.  After construction, I have tried the constructed power cable on my power amplifier, a Galion TS A75.  I voltage tested the connectors ends, which passed fine.  I fear my amp may be one such high current designs?  It immediately started a very audible ground loop, not quiet at all, one that resolved when changing my amplifier to receive a balanced connection.  I do connect DAC directly to power amp with no preamplifier, and am unsure then if there's any good fix to add the cable in my system without replacing the unbalanced for balanced connections.

Still curious to try the cable elsewhere, or try the interconnect designs, but for now do not think I can use the power cable as I'd intended, on my power amp.

@newkey1941 the hum may be caused by your DAC.

  • If it has a two pin power cable then it is not truly grounded

I had a Bryston amp that hummed if I disconnected my phono stage.

  • Turns out the Bluesound streamer (with a two pin cable) caused a hum.
  • But the phono stage was grounded and eliminated the hum when connected

A simple fix is to make a grounding wire that connects the neutral side of any unused RCA socket on the DAC to the ground of the mains supply

You can test it using a piece of wire attached to the ground of the mains and simply touch it to the neutral side of an RCA socket

You may ask why the hum is not present with the exiting power cable?

  • It’s probably due to the amp now works much better with the helix cable so the hum is more apparent

Hope that helps
