Sigma

Shunyata's more advanced conductor treatment and shielding throughout, near the top of the range.

Sigma sits near the top of the Shunyata range, with the company's more advanced conductor treatment and shielding applied throughout. As with every level, it covers mains, signal and digital cables at the same position. Below it, Alpha is the level at which the Shunyata approach shows clearly on a resolving system, and for many systems it is the sensible ceiling. Above it, Omega is built in small numbers for systems where power and signal are treated as components in their own right. At this level the distributor matters as much as the cable. A Sigma cable into an inadequate distribution point is not the best use of the money, and we would suggest addressing both together.

    Shunyata Research Sigma v2 XC Mains Power Cable - 1.75m

    SKU: Sigma v2 XC

    £2,708.33
    Ex. VAT

    The Sigma v2 XC by Shunyata Research is much like the Sigma v2 NR, except it is designed specifically for use with power conditioners. Like its sibling the NR, it benefits from sonic welding which joins metals together at a molecular level as well as proprietary CopperCONN™ Carbon Fiber connectors to ensure longevity. Like all other Shunyata cables the Sigma v2 XC undergoes Kinetic Phase Inversion Processing- a step up from simple burning in- so they are ready to deliver audiophile and medical-grade performance right out of the box.

    Please note: for the XC version, C19 is the standard termination. Longer lead times may apply for the C15 termination.
