The Vanguard of Power Cords: State-of-the-Art Shunyata Sigma Noise-Reducing (NR) Cable Provides Power Conditioning, Elevates System Fidelity, Requires No Burn-In Time

No power cord on the market touts the spare-no-expenses construction, cutting-edge abilities, and benchmark performance provided by the Shunyata Sigma Noise-Reducing (NR) cable. As the vanguard of Shunyata's latest cable series, Sigma NR features an array of state-of-the-art technologies that combine to turn what looks like a power cord into a device that does the seeming impossible. Equipped with a built-in wide-bandwidth CCI noise-filtration system that reduces power-line and component-generated power-supply noise – as well as built-in, second-generation Zitron technology that measurably lowers dielectric distortion while preserving the integrity of the original audio signal – Sigma NR doubles as a power conditioner for the amplifier, preamplifier, or source component to which it's connected. Indeed, the USA-made Sigma NR's meticulous design and vanishingly low resistance to peak current (DTCD) deliver unparalleled performance when used with even the most current-hungry amps. Shunyata's Kinetic Phase Inversion Process (KPIP) – a groundbreaking conditioning method that not only eliminates the need for time-consuming burn-in on your end but also elevates the overall fidelity of your system. You will hear invaluable sonic benefits – blacker backgrounds, lifelike detail, inner depth, explosive dynamics, revealing textures – when listening to music with Sigma NR in your setup. And now, you won't have to wait hours and hours for it to happen.

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. While Sigma NR isn't cheap, you could undoubtedly spend more. But why you would do so is beyond us. What you'll get will pale in comparison. 100% Music Direct Guaranteed.

“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

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.
