The Vanguard of Power Cords: Shunyata Sigma v2 NR (20A) Provides Power Conditioning, Elevates System Fidelity, Requires No Burn-In Time, Features True Carbon-Fiber Headshells

No power cable on the market touts the spare-no-expenses construction, cutting-edge abilities, and benchmark performance provided by the Shunyata Sigma v2 Noise-Reducing (NR) cord. 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 v2 NR doubles as a power conditioner for the amplifier, preamplifier, or source component to which it's connected. This is not your father's – or even your older brother or sister's – power cable.

First off, Sigma v2 touts several key sonic upgrades over its Product of the Year Award-winning predecessor. While you can read more about the key construction elements below, the use of VTX-Ag provides significant improvements in dynamics, accuracy, and low-level resolution while preserving the subtle tonal, textural, and timbral signatures that bring music to life. Sigma v2 NR also delivers more precise, time-correct presentations distinguished with an authoritative low end, pronounced contrasts, and transparent soundstages. What's more, carbon-fiber headshells eliminate layers of grain all the while claiming a ridiculously silent background. Last but not least, the redesigned NR v2 broadband filters filter lower in frequency than the original NR filters and are tuned to filter out specific frequencies of noise common to all component power-supply emissions. You'll hear increased three-dimensional imaging and greater access to extreme low-level details.

Indeed, the U.S.A.-made Sigma v2 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) is 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 v2 NR in your setup. And now, you won't have to wait hours and hours for it to happen.

So, what's exactly in Sigma v2 NR? Patented technology, exclusive metal treatments, and customized parts that outshine the construction involved with competitive products. It all starts with an ultra-pure OFE copper tube with a pure silver conductor at the center of the hollow core – all woven into massive, six-gauge VTX-Ag conductors linked to CopperCONN connectors. The latter contain true carbon-fiber headshells with anti-vibration qualities and pure copper contacts that claim higher conductivity principles than 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 v2 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.

"[T]he soundstage and imaging are so three-dimensional and holographic, it's as if you are being surrounded and enveloped within the music.... With the Sigma NR v2, my traditional perspective on what a stereo system can reproduce has shifted away from a language that describes gear to a language and sensibility that describes music. Remarkable, truly remarkable."
—Stephen Scharf, The Absolute Sound

Advanced Noise Reduction

Noise is an insidious problem that originates from many sources, including audio components themselves. Shunyata Research power cords employ proprietary internal noise-reduction filters that intercept noise, preventing it from propagating to other components. NR filters are specifically engineered to be non-reactive and compatible with all power-supply designs, including high-power amplifiers. This multi-element, wide-bandwidth noise-reduction technology was developed by Shunyata Research's medical division, Clear Image Scientific, to improve the performance of medical imaging systems in cardiology and neurosurgery.

CopperCONN Connectors

Shunyata Research has developed its own line of CopperCONN connectors that feature solid copper contacts and true carbon-fiber headshells that have anti-vibration qualities. These connectors are not just beautiful; they functionally reduce micro-distortions due to the carbon fiber's unique energy-absorbing, vibration-reduction qualities.

DTCD Design

Dynamic Transient Current Delivery is critical to performance for high-performance entertainment systems. All elements in Reference NR Series power cords, including the wires, contacts, dielectrics, and junctions, are tested and optimized using Shunyata Research's proprietary DTCD Analyzer. This optimization ensures outstanding low-frequency performance as well as dynamic contrasts akin to a live musical event. More than any other design parameter, Shunyata Research's ability to provide measurable dynamic instantaneous current is unparalleled.

VTX-AG Conductors

Reference NR Series cables feature an advancement in conductor technology that combines the transient speed and definition of pure silver with the warmth, power, and body of pure copper. VTX-Ag has a core conductor of pure silver with an outer concentric conductor of high-purity OFE copper. VTX-Ag provides significant improvements in dynamics, timing, precision, and low-level resolution while preserving the subtle tonal, textural, and timbral signatures that bring music to life.

KPIP Blackbird Process

Reference NR Series power cords are treated with Shunyata Research's proprietary Kinetic Phase Inversion Process. Four days of continuous KPIP processing dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation.

Class-Leading Performance In Each Product Category

Reference NR Series power cords consistently provide superb performance across a broad spectrum of electronic brands and component types. They truly redefine the performance envelope for all types of components, including amplifiers, preamplifiers, phonostages, D/A converters, disc players, and tuners.
