ΞTRON™ SIGMA Series of power cords are the most technically advanced products of their kind, incorporating multiple technologies that showcase Shunyata Research’s pioneering work in the area of Distributed Power Conditioning. SIGMA power cords work far more efficiently than traditional power conditioners because they intercept noise at its very source — the component power supply, and prevent it from being shared with other electronics in the system via CCI (Component-to-Component Interference).


The Σ SIGMA DIGITAL power cord was designed specifically to eliminate the extreme high-frequency noise associated with all digital source and computer system components that are now common to most high-performance audio/video systems. Σ SIGMA DIGITAL represents the first line of defense that prevents noise from being shared as interference with other electronics in the system. The Σ SIGMA DIGITAL uses massive eight gauge conductors so there is no compromise to DTCD® (Dynamic Transient Current Delivery) but should be used for front end digital components, rather than digital amps. For digital amps, the ALPHA HC or Σ SIGMA HC would be the most ideal in terms of performance.

The Σ SIGMA DIGITAL power cord utilizes Gabriel’s proprietary ΞTRON® circuit that has been designed specifically to reduce the extreme high frequency noise that is most commonly associated with digital source component power supplies. The noise-filter elements used in the Σ SIGMA DIGITAL power cord are entirely passive and non-reactive, meaning they will never get in the way of current flow, nor will they interfere with the power supplies of the components. No matter how complex or well designed a digital power supply is, the Σ SIGMA DIGITAL power cord will deliver a consistent, dramatic performance upgrade to literally any DIGITAL component application.

The Σ SIGMA ALPHA is more than large enough for all but the most extreme high-performance applications, so for those looking for a more reasonably priced and easy to use amplifier power cord, the Σ SIGMA ANALOG’s 8 gauge conductor mass is more than up to the challenge.
