The Vanguard Power Cable for Power Conditioners: Shunyata Sigma v2 XC (20A) Elevates System Fidelity, Requires No Burn-In Time, Features True Carbon-Fiber Headshells

No power cable on the market touts the spare-no-expenses construction, cutting-edge abilities, and benchmark performance provided by the Shunyata Sigma v2 XC. Created expressly for power conditioners and featuring built-in, second-generation Zitron technology that measurably lowers dielectric distortion while preserving the integrity of the original audio signal, Sigma v2 XC doubles as a power conditioner in and of itself. This is not your father's – or even your older brother or sister's – power cable.

While you can read more about the key construction elements below, the use of VTX-Ag provides significant improvements in dynamics, accuracy, and low-level resolution while preserving the subtle tonal, textural, and timbral signatures that bring music to life. Sigma v2 XC also delivers more precise, time-correct presentations distinguished with an authoritative low end, pronounced contrasts, and transparent soundstages. What's more, carbon-fiber headshells eliminate layers of grain all the while claiming a ridiculously silent background.

Indeed, the U.S.A.-made Sigma v2 XC's meticulous design and vanishingly low resistance to peak current (DTCD) deliver unparalleled performance when used with even the most current-hungry conditioners. Shunyata's Kinetic Phase Inversion Process (KPIP) – a groundbreaking conditioning method that not only eliminates the need for time-consuming burn-in on your end but also elevates the overall fidelity of your system. You will hear invaluable sonic benefits – blacker backgrounds, lifelike detail, inner depth, explosive dynamics, revealing textures – when listening to music with Sigma v2 XC in your setup. And now, you won't have to wait hours and hours for it to happen.

So, what's exactly in Sigma v2 XC? Patented technology, exclusive metal treatments, and customized parts that outshine the construction involved with competitive products. It all starts with an ultra-pure OFE copper tube with a pure silver conductor at the center of the hollow core – all woven into massive, six-gauge VTX-Ag conductors linked to CopperCONN connectors. The latter contain true carbon-fiber headshells with anti-vibration qualities and pure copper contacts that claim higher conductivity principles than common plated brass and bronze contacts. Advanced fluorocarbon dielectrics and sonic welding that mitigates junction points complete a power cord that combines meaningful innovations, objective measurement, an artisan's eye for detail, and discernible science in the name of provable, standard-setting performance.

While Sigma v2 XC isn't cheap, you could undoubtedly spend more. But why you would do so is beyond us. What you'll get will pale in comparison. 100% Music Direct Guaranteed.

CopperCONN Connectors

Shunyata Research has developed its own line of CopperCONN connectors that feature solid copper contacts and true carbon-fiber headshells 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 Transient Current Delivery is critical to performance for high performance entertainment systems. All elements in Reference XC 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 Conductors

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.

KPIP Blackbird Process

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.
