Duelund conversion to DIY Helix Geometry Cabling

@sns and @lewinskih01 - Interestingly enough, another member has just built a balanced power cable and he likes what he hears.

Basically, you have identical live and neutral conductors inside the helix coil, where the helix coil is the ground wire

1. Both live and ground conductors could be formed from 2 x 16 or 2 x 18 gauge UP-OCC bare wires, where each wire is inside a teflon tube
   • I would use a reverse twist on one of the conductors to mitigate some of the induction process e.g.
     • Live conductor would twist clockwise
     • Neutral conductor would twist anti-clockwise
     • Use a relaxed twist - i.e. one complete twist every 3"-4"
   • the 2 x 18 gauge live and neutral conductors should easily fit inside a helix coil made with a 5/16" rod,
   • but I am not sure about the 2 x 16 gauge version - it might
   • If your amp requires a large current draw then use 2 x 14 gauge wires
2. or alternately you could use the 2 x 18 gauge UP-OCC wire from VH Audio with the Airlok inuskation for the Live and Neutral
   • ​​​​​​​but using this method I would insert each twisted pair of conductors insitde a cotton sleeve to add some space between them

For both versions I would use a double coil ground conductor made from 2 x 14 gauge.. I think this would provide a better faraday cage effect to shield the Live and Neutral condctors

Personally - I would opt for #1, but #2 is a little easier to fabricate and the difference in performance would be small

Would it bs as good as the asymmetrical Helix PC used with a normal house supply?

• I do not think so because you still have the two conductors laying side by side, but the reverse twist on one conductor should help
• but using UP-OCC copper inside the teflon tubes will certainly sound much better than most branded products
• The key here is that you are using UP-OCC copper and if you use the teflon tube as the insulation then the impact of distortions from the insulation is minimized

If DIY is not an option then I would highy recommend Zavfino cables - they aill work very well with balanced power supplies and they use UP-OCC wires

Hope that helps - Steve

hello everyone, this is my first post here on the forum.  I have been watching the helix topic for a long time is a great project.  I already have power cables in the helix geometry, now I would like to try the helix geometry for the USB cable and hence my question is whether a double wiring configuration in separate fep tubes for d- and d + can be used for usb.  I hope I explained it well.  sorry for my english is not even sufficient

@beyco  - I'm not saying it cannot be achieved, but the pictures on my web site shows single wires.

Since it is his design, perhaps @grannyring can provide a better perspective on your question

@mbolek The Threads been quiet for a while, I have a question for you.

Did you receive your PC CCC  Wire Order?

If yes, has it been used and you have formed an assessment of it.

I have now been able to have been demonstrated the wire in use, from Source to Speaker on a friends system who I introduced to the wire.

The Vinyl LP as a Source on my friends system, now has developed to the wire being in use as an internal Tonearm Cable, Interconnects with Selected Low Eddy Connections on the Cables and Phonostage Chassis, Internal Phonostage Hook Up wire and the Power Cord, the Speaker Cables are also using the same wire.

This is a system I am very familiar with, and when presented as the system owner had wanted it to be heard, it was without doubt, the best I have ever heard this system.

I was gobsmacked at how a Cable that sounded very good when demonstrated, was shown to be presenting as quite inferior when compared to the same Cable ng with a different RCA Connector, especially a RCA selected for the Low Eddy Properties. This is indescribable and is needed to be experienced.

When the exchanges were carried out, the Low Eddy Signal Path was able to present Notes and Vocals with a Envelope Shaping, in a manner I don't ever recall being able to perceive.

The system owner has also made it known, the wire has created such a positive impression, if the wire could be discovered to be purchased in a gauge to suit a MC Coil, they would send a Ortofon Cart' away as a Donor Cart', to a rebuild service, to have the Aucurum Wire replaced with it. That is quite a serious move toward this wire type in anybody's assessment. 

The wire is available in very fine gauge 0.03mm as a Screening Mesh, but is only found in assembled cables, a 0.18mm is the finest I know of in a stranded wire. 

Let's say you're using double solid core hot leads and double stranded grounds.  What direction should the hot pairs be twisted and what direction should the grounds be twisted around them?
