ΞTRON® Σ SIGMA
The defining feature of each Σ SIGMA power cord are Shunyata’s highest performing ΞTRON® circuits, which measurably reduce noise at the first point of electrical contact with component power supplies. No power conditioner in the world can capture noise at the first stage of a component's electrical circuit and isolate that noise from other components. This ultra-efficient means of noise reduction virtually eliminates CCI (Component-to-Component Interference) and protect electronics in the system from being affected by commonly shared noise.
Essentially, Σ SIGMA Series power cords function as independent, high-current power conditioners. All three Σ SIGMA power cord models cancel the specific frequencies of noise associated with the class of components they are designed for -- Digital, Analog or High-Current.
Σ SIGMA model power cords are entirely non-reactive. They present no interference or impedance challenge to electronic power supplies (Unlike most power conditioners). What this means is, Σ SIGMA power cords are complementary to all electronic power supplies within their named classification and allow all components to perform at peak efficiency both in terms of current delivery and lowered noise.
Please compare our power cables with the Component Selection Guide and Power Cord Comparison Chart.
Σ SIGMA DIGITAL and ANALOG model power cords are all constructed using Shunyata’s finest VTX wire formed into massive gauge conductors, making them compatible with high-current electronics, but the Σ SIGMA HC is uniquely designed for the world’s most demanding amps and power conditioners with an even larger 6 gauge conductor complement and unique internal construction. Each Σ SIGMA power cord is designed and tested for optimum delivery of DTCD (Dynamic Transient Current Delivery).
15 Year Evolution
Every facet of the Σ SIGMA model construction has benefitted from designer Caelin Gabriel’s obsessive attention to detail, along with his fifteen years worth of patented science, technology and parts development. Without question, the finest examples of Shunyata’s reputation as the world’s finest manufacturer of electrical and signal systems are the Σ SIGMA power cords -- the most technically advanced products of their kind.
The ΞTRON® Σ SIGMA contains a hybrid ΞTRON® circuit that measurably reduces power noise generated by the component itself. Essentially it is a power cable with a power conditioner built in, but without any of the negatives normally associated with active power conditioning boxes.

The Σ SIGMA HIGH CURRENT power cord was developed exclusively for extreme high-current applications such as amplifiers and power conditioners such as the HYDRA TRITON, tasked with powering full systems of electronics. Every facet of the Σ SIGMA HC has been optimized for maximum DTCD (Dynamic Transient Current Delivery) efficiency due to its massive 6 gauge conductor compliment and minimal measured impedance.
The Σ SIGMA HC also utilizes Gabriel's proprietary ΞTRON® circuit that has been designed specifically to reduce the frequencies of noise that are most commonly associated with high-current components such as amps, projectors and multi-component power conditioners. The noise-filter elements used in the Σ SIGMA HC 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, making the Σ SIGMA HC the ideal compliment to any high-current application.
For more modestly powered amps or power conditioners with lighter loads, the Σ SIGMA ANALOG is more than large enough for all but the most extreme high-performance applications.
- High-Current Amplifiers
- High-Current capable power conditioners (HYDRA TRITON)
- High-Performance Projectors
- Recording Panels (Neve 88 and others)
- High-Current Subwoofers (Wilson’s Thors Hammer etc)
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.
- Phono electronics of all types
- Power conditioners
- Reel To Reel Decks
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.
