Shunyata Research’s new Reference Line power cords were developed using the same materials science and technologies that make the Omega 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 and models.  The Alpha is a level up from the Delta and represents the best price-to-performance in the lineup.  The Sigma 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.

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.
