Product Description

Reference XC cables are designed specifically to optimize the performance of Shunyata Research power conditioners. The Sigma XC cables eschew noise reduction features in favor of enhanced DTCD (dynamic transient current delivery). Using proprietary conductors and parts developed for the Omega XC, the Sigma XC delivers pace-setting DTCD™, optimizing power conditioner performance.

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.

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


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.


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.


Reference XC 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.


Reference XC 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.
