Shunyata Research Sigma v2 NR Noise Reduction Power Cable

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 world's 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 who 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 Sigma v2 NR cable to previously unattainable levels of performance.

The Sigma v2 NR is an ideal power cable for source equipment like CD players, DACs, tuners, and preamplifiers and it makes an excellent amplifier cable with its high-current conductors and exclusive noise-reduction capabilities. The Sigma v2 XC is the ideal mate to the Sigma v2 NR to power your Shunyata Research power conditioner.
