Shunyata Sigma V2 XC Power Cable

Shunyata Research’s new Reference 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. 

All 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. Shunyata Research’s own CopperCONN™ connectors propel the Delta v2 cables to previously unattainable levels of performance.

Reference XC cables are designed specifically to optimize the performance of power conditioner and high-current amplifier performance.  The Delta v2 XC cables eschew noise reduction features in favor of enhanced DTCD (dynamic transient current delivery).  


Every facet of the Sigma v2 XC power cord has been refined to deliver measurably superior Dynamic Transient Current Delivery.

DTCD™ Analysis is a technique that measures instantaneous current through low impedance electrical conductors and contacts.  Shunyata Research uses it to optimize the design, specification and construction of parts and materials to ensure maximum current delivery performance.  Each part, conductor, noise circuit and material inside the Sigma v2 XC allows for maximum throughput of instantaneous current.

Listeners will experience earth-shaking low-frequency performance from even the highest-current amplifiers as well as dynamic contrasts unheard of outside of a live event.  More than any other design parameter, Shunyata Research’s skill in eliminating resistance and maximizing peak-current delivery is unmatched.

The Sigma v2 XC is a true reference caliber cable for power conditioners or high-current amplifiers.  It allows high-performance power conditioners like the award winning DENALI 6000/S power conditioner to deliver their maximum potential.


Reference model 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.


Shunyata Research has developed its own line of CopperCONN™ connectors that feature solid copper contacts that have superior conductivity compared to bronze or brass contacts used in common connectors.

These connectors are not just beautiful, they functionally reduce micro-distortions.  They are hermetically sealed with an electrically inert compound that protects the contacts and wires from corrosion.  This also ensures that the wires cannot become loose, fray or pull out from the head shell.  This guarantees a lifetime of reliable performance that does not degrade over time.

Crystalline highs and breathtaking clarity and thunderous bass capabilities make the Sigma v2 XC a top tier choice for the incredible Everest 8000 power conditioner!


The proprietary Shunyata Research, Kinetic Phase Inversion Process was created to significantly reduce the amount of time required to burn-in cables and power conditioners. It also has a performance enhancing effect above and beyond simply burn-in.

Four days of continuous KPIP™ processing dramatically reduces the ups and downs for new equipment and significantly improves sonic performance, delivering a relaxed and life-like presentation.
