Key Features and Performance

  • Advanced Noise Reduction (NR) Technology: Reduces power-line noise and component-generated interference, creating a pristine backdrop for enhanced clarity and detail retrieval.

  • Patented QR/BB Technology: Functions as a power supercharger, providing reserve levels of DTCD (Dynamic Transient Current Delivery) energy for improved timing and transient response.

  • Optimised for High-Performance Systems: Ideal for high-end components demanding the utmost in noise isolation and power optimisation, ensuring maximum system performance.

  • Silent Background for Immersive Sound: Creates an "island of silence" that allows subtle details, spatial imaging, and soundstage precision to shine without distortion or interference.

Three Distinct Models to Choose From:

SIGMA-X QR

The SIGMA-X QR is the highest-performing model in the SIGMA-X series, incorporating patented QR/BB™ technology from the flagship OMEGA QR. QR (Quick Release) Technology acts as an electrical charge reservoir, enhancing access to instantaneous current for improved dynamics and reduced strain, especially in high-powered amplifiers. With Gen3 NR noise reduction, the SIGMA-X QR excels with amplification systems and is equally suited for source and digital equipment when peak performance is required.

SIGMA-X NR

The SIGMA-X NR delivers reference-grade performance with advanced noise reduction, making it ideal for amplifiers, sources, and line-level components. Featuring NR (Noise Reduction) Technology, its multi-stage filter networks effectively reduce power-line and component-generated noise, enhancing the clarity and purity of sound across all connected electronics. The SIGMA-X NR provides a substantial performance upgrade, whether used with amplification or source equipment.

SIGMA-X XC

The SIGMA-X XC is a high-performance wall-connection power cord tailored for Shunyata Research power distributors. Designed with XC (eXtra Current) Technology, it ensures unrestricted high-current delivery, making it ideal for connecting power distributors or conditioners to wall outlets. By omitting NR filters, the SIGMA-X XC focuses on continuous current flow, ensuring power-hungry components receive the energy needed for peak performance while relying on the advanced filtering within Shunyata’s power distributors.

A Transformative Listening Experience

The SIGMA-X NR delivers an immersive listening experience akin to witnessing a film so captivating that you lose awareness of its medium. With its unparalleled ability to reveal the finest nuances of sound, the SIGMA-X NR offers a soundstage of lifelike immediacy and depth. Instruments and voices emerge with exceptional clarity and three-dimensional weight, while the dynamic range is presented effortlessly and naturally. Its hallmark is a profound silence within the music, enabling a deep emotional connection to every performance.

The impact of the SIGMA-X NR is immediate and unmistakable, transforming your listening experience into something truly extraordinary.

A New Benchmark in Power Cable Design

The SIGMA-X NR represents a groundbreaking evolution in power cable design, informed by Shunyata Research’s innovations in both the medical and recording industries. This development signifies the most significant progression since Shunyata’s founding in 1998, setting a new standard for noise reduction and dynamic performance.

As part of Shunyata’s Reference Series, the SIGMA-X NR is a testament to the company’s 25-year dedication to crafting the finest power cables available. It delivers unmatched performance in its category, ensuring that every system it powers achieves its full potential.

For those seeking exceptional noise reduction and dynamic clarity, the SIGMA-X NR is the definitive choice in high-end audio power delivery.

NR Noise Reduction: Shunyata Research’s exclusive NR (Noise Reduction) technology is a multi-stage filter network that measurably reduces power-line and component-generated noise, producing better purity of tone and clarity. It delivers a stunning background of silence to recordings, allowing the listener to hear into recordings as never before.  Every nuance of meaningful content is revealed, bringing to life music’s most consequential moments as if the performers are in the room with the listener.

TAPc: The SIGMA-X features the all-new TAPc technology. TAP (transverse axial polarizer) is a patent pending technology that Shunyata Research developed to improve the performance of its reference signal cables. The TAPc technology is a radical advancement of the TAP technology that enables a significant reduction in the size of the modules – and for the first time allows this technology to be applied to power cords.

The sonic results of TAPc include a cavernous drop in perceived noise floor, effortlessly portrayed dynamics and a superb rendering of timing and coherency. The sonic benefits of the TAPc technology are quite simply unique and cannot be replicated by any competing product or technology.

Even to an untrained ear, the effects of the TAPc are immediately apparent and repeatable across a variety of components and systems. In essence, the TAPc modules are force-multipliers that elevate the listening experience to a level many would not imagine possible.

Gen3 NR:  Perhaps no technology has been more thoroughly researched, measured and third-party tested than Shunyata Research’s power line noise reduction technology. Gen2 NR technology, as used in the Gamma and Theta power cord lines, has been proven effective in heart surgery labs across the U.S. and Europe. Countless iconic recording engineers, mastering studios and musicians have provided vivid accounts supporting the efficacy of Shunyata Research’s NR power cords.

The Gen-3 NR circuit, as used in the ALPHA-X and SIGMA-X power cords, improves upon the sonic performance of the Gen-2 circuit. Transient speed, transparency and purity are all significantly improved along with an improvement in micro-dynamics. The new NR circuit is also more compatible across a broader spectrum of electronic component types; including preamplifiers and power amplifiers. Even amplifiers operating in pure Class A will realize a significant benefit when using our Gen3 NR equipped power cables. (The SIGMA-X XC power cords are now, primarily, recommended for use with power distributors.)

KPIP v2™ Shunyata Research’s proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP v2™ processing which refines conductor metals at a molecular level. This dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation. When compared to the original process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade.

VTX-Ag: Shunyata’s VTX-Ag cables are uniquely constructed with an inner and a centre conductor made of pure silver and an outer concentric ring conductor made of pure copper. It’s made using the finest fluorocarbon insulation to minimize dielectric absorption and re-radiation, which improves resolution and clarity. VTX-Ag delivers the speed and clarity of silver and the midrange warmth and three-dimensional power in the lower octaves of copper without imparting any of the negatives associated with either metal. – The best qualities of silver and copper combined.

OFE Alloy 101: Shunyata Research uses only the highest purity of copper available for the production of its wire products. ‌‌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—certified by ASTM F68 ‌‌C10100.

Fluorocarbon dielectrics are usually only found in wire used in the aerospace industry, satellites and only the most expensive audiophile cabling. It has special electrical characteristics; very low dielectric absorption, high dielectric strength and exceptional heat resistance.  When used in audio and power cables is reduces the perception of dynamic compression and it improves sonic low-level resolution and clarity.

Crystal clear transient detail.

CopperCONN: Many audiophile-grade connectors are made from brass or bronze. While some may get a plating of silver, gold or rhodium, most of the current is carried by the contact’s base metal. ‌CopperCONN® connectors contain pure copper contacts with much higher conductivity than brass. The difference in performance is clearly audible.
