A RADICAL PROGRESSION

The most radical progression in power cord design since Shunyata Research's humble beginnings in 1998, has delivered a watershed level of performance with the introduction of the SIGMA-X power cables.

Inspired by our well documented success in medical imaging and recording industries, Shunyata Research has continued to advance the science and technology of its most successful products. The SIGMA-X power cables have exceeded even the highest performance expectations.

The SIGMA-X is second only to Shunyata Research's ultimate Omega power cord within the "Reference Series". The Reference Series X cables represent the culmination of a 25-year commitment to produce the absolute finest performing power cables available.

GROUNDBREAKING TECHNOLOGY

There are several definable advances to the Sigma-X power cord designs that will distinguish themselves within seconds after application, comparisons and testing. The Sigma-X QR model is elevated by the inclusion of our patented QR/BB tech which has a profound effect on instantaneous current availability.

TAPc Technology

The SIGMA-X features the all-new TAPc technology. TAPc (Transverse Axial Polarizer) is a patent-pending technology that couples to the electromagnetic fields surrounding electrical or signal conductors. TAPc behaves like a polarizer, passively reducing electromagnetic distortion that presents as a type of glare on sound or images.

The sonic impact of TAPc is unmistakable. There is a profound drop in perceived noise floor, effortlessly portrayed dynamics and an immediate improvement in the rendering of timing and coherency in sound. These performance elements are unique to TAPc and remain unaddressed by competing technologies of any kind. Even casual listeners can recognize the effect TAPc has upon first listen. Results are consistent across a wide range of components and systems. Essentially, the TAPc modules act as force multipliers, elevating the listening experience to levels many would not have thought possible.

QR/BB Technology

True to its reputation for migrating its most profound patented technologies into more affordable products, Shunyata Research has done it again. Previously found only in the ultimate Omega power cords, the QR/BB™ module takes a wrecking ball to power cord performance expectations. The QR/BB™ module possesses the ability to act as an electric charge reservoir, meaning it stores and releases energy in a manner that improves a component's access to instantaneous current. Dynamics are actually improved, reducing any sense of dynamic strain often heard from amplifiers that are connected with lesser power cables. The sonic result is a lifelike presentation of timing and dynamic contrasts in sound that cannot be replicated by ANY other means.

The SIGMA-X QR creates an island of pure silence when used with reference quality amplifiers and source components. The QR/BB technology essentially supercharges the component's power supply with reserve levels of DTCD energy.

For the first time, this remarkable QR/BB technology is available at a much lower price in order to reach far wider audience.

THREE DISTINCT MODELS TO CHOOSE FROM

SIGMA-X QR
The SIGMA-X QR edition is the highest performing SIGMA-X model. It includes patented QR/BB technology descended from the ultimate OMEGA QR along with Gen3 NR noise reduction technology. It is particularly suited to use with high powered amplifiers but can be used for source and digital equipment when only the highest levels of performance are demanded.

SIGMA-X NR
The SIGMA-X NR delivers reference-grade performance and noise reduction on any and all electronics. Whether on amplifiers, sources or line-level components the SIGMA-X NR offers a massive component-upgrade level of performance.

SIGMA-X XC
SIGMA-X XC was designed specifically for use as a wall-connection power cord for use with Shunyata Research power distributors. Due to the extensive levels of filtering in Shunyata Research designed power distributors, NR filters are not needed at the wall connection. For use with other manufacturers power conditioners, the NR models will likely provide a performance benefit.

Bringing it Home
Have you ever watched a film that was so engrossing and captivating; the performances so real that you forgot you were watching a movie? That would be an apt description of the SIGMA-X power cord's impact on sound, recording and imaging. There is an immediacy to sound, an immersive rendering of recorded detail that makes it easy to focus on the music and to forget about the recording chain.

The dramatic performance SIGMA-X power cords impart is not subtle or amorphous, it is revelatory and impossible to dismiss. When the recording calls for it, SIGMA-X power cords unleash a perfectly timed storm of three-dimensional weight and dynamic intensity – without a hint of compression or artifice. Perhaps the signature attribute of the SIGMA-X performance is its rendering of an almost gravitational silence within voice, instruments and images on a recording. There is a truth and precision to sound that is unmistakably free of distortion, leaving the listener captivated by an intense connection to favorite music.
