Reference NR / XC Series

Shunyata Research’s new Reference NR & XC Series power cords were developed using the same materials science and technologies that make the Omega QR the market’s ultimate cost-no-object power cord.

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 Connectors

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.

Shunyata Research’s new Reference NR Line power cords were developed using the same materials science and technologies that make the Omega QR the market’s ultimate cost-no-object power cord.  The Reference Line power cables are designed to be used with the worlds finest audio components.

There are three levels of performance in the Reference Line starting with the Delta v2 NR and Delta v2 XC models.  The Alpha v2 is a level up from the Delta v2 and represents the best price-to-performance in the lineup.  The Sigma v2 takes top honors in the line for those that must have the best. All three Reference models feature Shunyata Research’s exclusive VTX-Ag conductors that combine an ultra pure silver with a concentrically wound layer of OFE copper.  This provides the speed and transparency of silver with the richness, tonal color and power of pure copper.

Using proprietary conductors and parts developed for the Omega QR, the Reference NR Series delivers pace-setting performance in each product category. Noise reduction technology and Shunyata Research’s own CopperCONN™ connectors propel the Alpha v2 NR cable to previously unattainable levels of performance.
