The Apex of Audio Performance, Technology, Construction, Science, and Engineering: Shunyata Sigma Speaker Cables Provide Reference-Setting Sound and Beguiling Audio Performance

Behold greatness: Shunyata Sigma speaker cables represent the apex of audio performance, technology, construction, and engineering. They epitomize reference-setting high-end sound – helping reproduce music to a level that seems, to human ears, beyond belief. While by no means inexpensive, Sigma speaker cables offer proven scientific innovation and US-made build quality for a cost that belies the price of other, cost-no-object cables that provide far less and rest their laurels on hyperbole. Sigma speaker cables give you a distortion-free final connection to your loudspeakers that is failsafe, quiet, pure, and powerful. Multiple patented and patent-pending technologies afford Sigma advantages no other cable on the market – independent of price – can impart.

A new, breakthrough proprietary device called HARP reduces current resonances within speaker cables – a concept analogous to the use of diffusion panels that treat frequency irregularities in room acoustics. Second-generation Zitron technology measurably lowers dielectric distortion while preserving the integrity of the original audio signal. Sigma also touts Shunyata's Kinetic Phase Inversion Process (KPIP) – a pioneering conditioning method that eliminates the need for time-consuming burn-in on your end and elevates the overall fidelity of your system. Because of this, Sigma speaker cables don't require any time to sound their best. They are ready to go out of the box. Sigma boasts equally formidable construction.

Loaded with exclusive metal treatments and customized parts, Sigma speaker cables are comprised of ultra-pure OFE copper woven into massive, six-gauge VTX hollow-core conductors. Advanced fluorocarbon dielectrics and sonic welding that utilizes high-energy sonic waves to literally join metals together at a molecular level – and eliminate any need for inferior soldering, crimping, and brazing methods – complete a speaker cable that elevates the art of music and audio to a new, emotionally and physically beguiling plane. 100% Music Direct Guaranteed.

“The Sigmas are flat-out fabulous across the key areas of dynamic fluidity and stability, soundstaging and imaging, resolution of detail, tonal complexity, and musical completeness.”

The Absolute Sound, July/August 2018 

"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

HARP: Like Having Acoustic Room Correction Tech in Your Cables
HARP was discovered through Shunyata's research into current drift and audio-frequency current resonances that occur in speaker cables. Theoretically, a speaker cable may develop current resonances in the audio band, being roughly analogous to standing waves (modals) in room acoustics. The HARP module acts as a current mode diffraction device that breaks up such resonances, improving the perceived resolution and coherency of the system.

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 cryogenic 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 Sigma Series.

OFE 101 Copper for Unsurpassed Purity
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.

ArNi Wire
ArNi® is a type of wire created by Shunyata Research designed to be the finest quality wire available for audio purposes. It begins with the highest-purity or copper available. It is then formed in virtual hollow tubes, eliminating skin effects and eddy current distortions. And finally, the wire undergoes Shunyata's proprietary KPIP process.

STIS Speaker Terminal System
STIS is designed to eliminate the high cost and complication of speaker-cable termination. The system makes it possible to use the same speaker cable with a variety of different amps and speakers. If a spade is damaged, you can simply replace it without sending it to the factory for re-termination. STIS interchangeable terminals have undergone extensive user listening tests to ensure they provide the finest audio performance that is equal or superior to non-replaceable, soldered terminals.
