Upgrading power cord.. proven upgrade? or crap?


The thing i cannot understand is how a new high quality cable will enhance the quality of the flow of electricity that previously went into cheap house electrical wires ?

it's like saying that with good equipment u'll get a higher than CD sound from a FM stereo source or a cheap Mp3 ..

please help me understand .. :)

Over the past few years I have been experimenting with building my own power cables...
- not simply adding high quality (high priced) connectors to high priced bulk cable (but I started with this approach)
- I now actually hand wind the conductors into different geometries/architectures.

What I have observed...

#1 - high priced bulk cables with high quality connectors attached provide the least improvement - but are still better than stock power cables

#2 - Braiding the conductors is significantly better than bulk cable - even when made from household romex - NOTE: romex will break is bent a few times, so don’t use this - I used romex just to test a theory.

#3 - winding the neutral and ground conductors around the live conductor in a tight helix geometry provided the biggest improvement.

#4 - for #2 and #3 their conductor geometry rejects EMI and RFI and therefore shielding is not required unless you are in a very noisy environment like a recording studio with cables all over the floor

Other observations common across all geometries...

- for the live conductor - use the best quality wire you can afford, I use conductors from a piece of Furutech bulk cable

- for the neutral conductor - reasonable quality copper conductor seems to be as effective as high quality Furutech - I use silver plated copper conductors

- for the ground conductor - Home Depot’s best multi strand house wire is good enough

- crimped spades worked better than clamping bare conductors in the connectors

- components actually run cooler using helix design cables

As for the "science" it all boils down to the inductance of noise across in internal conductors of the power cable...

Inducing noise into the neutral line effects the performance of the connected component(s) by increasing distortion levels - A good power cable will reduce, maybe even eliminate that effect.

I now use helix design PC’s and IC’s across the entire system and it has never sounded so good.

Hope that helps :-)
P.S. if you are wondering what commercial cables might use these geometries...

Anti Cables has braided power cables and they also sell helix IC’s

I believe the Shunyata Venom uses a spaced helix geometry

Neotech has a very complicated helix geometry in at least one of their high end cables

Those are just some that I know of 😊

I just tried the Shunyata Zitron Alpha HC on my Sanders Magtech and can tell no difference between it and my cheap, Groneberg.  I emailed Roger Sanders, and he says that audiophile power cords are a hoax.
Power cords made the biggest difference in my system....more than interconnect, speaker cables.
