Soundstage has just posted a review of the Orion Helix speaker cable and Antares Helix IC. Findings are intriguing if not definitive and may give some indication of the sound of the Helix PCs. See:

In the meantime, tomorrow I may have the opportunity of comparing a Shunyata Python Helix VX with an Electraglide Epiphany. I will post my findings.
Willster, the patent for the braided geometry used by Shunyata is not Shunyata's own, but it is applied under license. This may explain some of the usage of similarly braided geometries by other companies such as Siltech.
