Shunyata Research Sigma NR Power Cables, 2 meters, 20 amp

Shunyata Research Sigma NR (Noise Reducing) Power cable, 20 amp (C19 connector), length 2 meters (this is longer than the standard 1.75 m, custom order). This was Shunyata's top of the line through last year (version v2 just came out and at a higher price).  This is great for power hungry applications, mono blocks, power conditioners, distributors, heavy preamps, etc.

Loaded with patented technology, exclusive metal treatments, and customized parts that outshine the construction involved with competitive products, USA-made Sigma NR cords are comprised of ultra-pure OFE copper woven into massive, six-gauge VTX hollow-core conductors linked to CopperCONN connectors. The latter contain pure copper contacts that claim higher conductivity principles than the common plated brass and bronze contacts. Advanced fluorocarbon dielectrics and sonic welding that mitigates junction points complete a power cord that combines meaningful innovations, objective measurement, an artisan's eye for detail, and discernible science in the name of provable, standard-setting performance.

KPIP: Kinetic Phase Inversion Process Eliminates Need for Burn-In
Shunyata founder Caelin Gabriel developed KPIP after years of research into the underlying causes of various effects such as burn-in, wire directionality, and cryogentic treatment. He discovered an underlying core principle that burn-in and cryogenics only partially addressed. Once the governing principle was understood, it became possible to create a processing technique and machine that could virtually eliminate the need for burn-in and cryogenic treatment.

Second-Generation Zitron Technology: Lowers Distortion, Preserves Signal Integrity
The internationally patented Zitron technology is the most compelling of Shunyata Research's technologies given its ability to measurably lower dielectric distortion and preserve the original signal's integrity. It requires a special type of conductor that has two signal paths and an electric field compensation circuit that creates a cancellation signal that prevents the insulation from developing a charge. Zitron cables have earned a legendary reputation among reviewers, customers, and sound professionals for their ability to eclipse the performance of even cost-prohibitive cables. Caelin Gabriel's research has evolved to a second-generation Zitron technology that is making its debut in Alpha Series.

CopperCONN Connectors
Many audiophile grade connectors are made from brass or bronze. Wile some may get a plating of silver, gold, or rhodium, the majority of the current is carried by the contact's base metal. CopperCONN connectors are with pure copper contacts, which have much higher conductivity that brass. The difference is clearly audible. 

Highest-Purity Copper for Supreme Conductivity
OFE Alloy 101, or C10100, is the highest grade of copper, with a minimum 99.99% purity and a conductivity rating of 101% IACS. OFE stands for oxygen-free electrolytic and supersedes the term OFHC (oxygen-free high conductivity). C10100 is the only grade of copper that comes with a written certification of purity.

Hollow-Tube VTX Conductors: A Shunyata Exclusive
Shunyata Research's exclusive VTX conductors are made in the shape of hollow tubes. Since current can only travel through the outer rim on the wire, no skin effects or random eddy currents occur. VTX conductors are made from pure OFE C10100 or Ohno (single-crystal) copper.
