Shunyata Research Zitron Sigma Analog Power Cable (1 meter)

The mission of Shunyata Reseach is to lead the field in technical innovation and custom-parts engineering, and to create power and signal audio products of the highest quality and performance.


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 ANALOG power cord was developed exclusively for all electronics that use linear design anaolg power supplies, such as pre-amplifiers, modest to moderate current-draw amplifiers, phono equipment and any and all line-level components. The Σ SIGMA ANALOG can also be used for power conditioners that are powering modest systems comprised of fewer than 5 components. The Σ SIGMA ANALOG has been optimized for maximum DTCD® (Dynamic Transient Current Delivery) and compatibility with the broadest possible range of electronics, regardless of design within the ANALOG power supply realm.

The Σ SIGMA ANALOG power cord utilizes Gabriel’s proprietary ΞTRON® that has been designed specifically to reduce the frequencies of noise that are most commonly associated with ANALOG component power supplies. The noise-filter elements used in the Σ SIGMA ANALOG 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. The Σ SIGMA ANALOG the ideal power cord counterpart to any ANALOG component application.

The Σ SIGMA ANALOG 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.
