Product Description

The Finest High-Current Power Cable Made: Product of the Year Award-Winning Shunyata Sigma HC Functions as an Independent Power Conditioner, Cancels Class-Specific Noise Frequencies. The defining feature of each Sigma power cord relates to Shunyata’s highest-performing ZiTron circuits, which measurably reduce noise at the first point of electrical contact with component power supplies. No power conditioner can capture noise at the first stage of a component’s electrical circuit and isolate that noise from other components. This ultra-efficient means of noise reduction virtually eliminates CCI (Component-to-Component Interference) and protect electronics in the system from being affected by commonly shared noise. Essentially, Sigma power cords function as independent, high-current power conditioners.
“Shunyata continues to push the state-of-the-art in AC power. The Sigma is the best cord Shunyata has made, improving on previous models by deepening background silences , increasing resolution at the lowest levels, rendering textures more realistically, allowing the rest of your components to sound their best. Robert Harley’s reference.”
– The Absolute Sound, 2015 Product of the Year Award

“The Sigma and Alpha NR Series AC cables have continued Shunyata Research's move to greater noise reduction, definition, and transient speed from a lusher, fuller sound that characterized their earlier CX Series of AC cables circa 2009.”
—Steven Plaskin, Audiostream

"By removing so much noise and interference from the path, Shunyata's flagship cables renewed my passion for recordings I'd begun to take for granted.”
—Vance Hiner, The Audio Beat

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.
