Reference NR / XC Series

All Reference Series models are priced to be accessible for a range of budgets.

Using proprietary conductors and parts developed for the Omega QR — the Reference NR & XC Series deliver pace-setting performance in each product category.

Standard length of cable is 1.75 meters.

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 head-shells ( Alpha and Sigma models ) 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 Instantaneous 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.

Three Models , three superior performers & Class-leading Performance in each Category

The Reference NR & XC 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, pre-amplifiers, phono-stages, D/A converters, disc players, and tuners.

— For digital-output only electronics, such as clocks, transports, servers, disc-arrays, NAS, computers, routers, network bridges, and for video/film applications, we recommend our value-oriented Venom NR Series power cords. 

Shunyata Research stands alone as the industry leader in patented power technologies and measurably verifiable performance.
