DIY Helix Geometry Cabling

Thanks Steve, I have enjoyed making these and experimenting with different wires and dielectric's. Your efforts in keeping the knowledge base accessible is appreciated.

Thanks for posting. I assume the helix acts as a shield and that there is good noise rejection when used as interconnects. 

One thing I forgot to mention - the Audiogon Private Messaging feature...

• for some reason, when I try to use this feature the following message is displayed
  • You must have a verified phone number and payment method to send messages.
• Since I am extremely guarded in my use of my "payment informtation", this is not going to happen
• so for the time being please DO NOT use private messaging to contact me
• I will monitor this thread for any questions

Many Thanks - Steve

@noromance - the purpose of the helix neutral is two fold

#1...

• to stop the alternating voltage in the signal wire from inducing "noise" into the neutral wire, which utlimately is fed back into the neutral side of the circuits of the connected components.
• Noise on the neutral side of the circuit impacts the ability of the circuit to perform as designed
• When used on all cables in a system noise is elimanated throughout the system.

Some say this is negligable, but at each "stage" that noise is amplified and as such creates a significant problem by the time it reaches the speakers.

The speakers have the highest voltages, so they make the biggest impact to the neutral side of the amplifier

On the power cable side of things - any noise on the neutral permates through the entire system via the attached components and contributes greatly to system wide noise issues

#2...

• The helix spiral acts like a faraday cage around the signal wire
• it minimizes the impact of "external noise" on the signal wire(s) by disrupting the "Space" around them
  • a bit like a screen

Yes - Noise rejection is very good, both from external sources and internal cable  signal induced noise

• e.g. I once held a standard turntable cable (i.e. from the MC cartridge to the phono) tightly n my fist, against a Helix power cable
• to even my surprise, whilst there was a very small amount of hum coming from the speakers is was only audible when the amp was turned to very high levels

Hope that helps - Steve

Thanks for posting Steve. I'm looking forward to trying my hand at building, starting with power cords. 

@williewonka Thanks for taking the time to answer. 

@williewonka Many thanks for bringing back the information.

@williewonka Thank you for providing a valuable service to the audiophile community. I've been making the power cables for years using various types of wire and gauges of that wire, just exceptional PC's. This in comparison to PC's II've owned and others I had borrowed from lending library at CableCompany, these at many price levels, up to $7k for six foot runs, accounting for inflation likely at least $10k in today's dollars. What amazes is the seemingly complete absence of dynamic restriction, add amazingly low noise floor, windowless transparency, and then you can tune via the wire, guage of wire and AC connectors. Really, just a perfect AC cable, sold off vast majority of my AC cables from well known manufacturers, full loom of these, done with cabling for good.
