A Power Cord That Defeats Noise, Lowers Distortion, and Serves as a Power Conditioner: Reference-Level Shunyata Alpha Noise-Reducing (NR) Cable Features KPIP, Second-Gen. Zitron Technology

The Shunyata Alpha noise-reducing (NR) power cord permanently changes the meaning of "reference-level" in the power cable field. Equipped with on-board CCI noise-reduction filters that concurrently defeat analog and digital noise – as well as built-in, second-generation Zitron technology that measurably lowers dielectric distortion while preserving the integrity of the original audio signal – Alpha NR doubles as a power conditioner for the amplifier or source component to which it's connected. Designed to handle even the highest-powered amps, Alpha NR's unprecedented capability extends to 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 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 Alpha 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 far surpass the construction of competitive products, USA-made Alpha NR cords are comprised of ultra-pure OFE copper woven into massive, eight-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 round out a cable whose noise-reduction capabilities can not only be measured, but felt during the listening experience. If you're ready to hear the new reference, Alpha NR is prepared to blow you away. 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

KPIP (Kinetic Phase Inversion Process)
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 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.
