The Finest High-Current Power Cable Made: Product of the Year Award-Winning Shunyata Sigma HC Functions as an Independent Power Conditioner, Cancels Class-Specific Noise Frequencies. The defining feature of each Sigma power cord relates to Shunyata’s highest-performing ZiTron circuits, which measurably reduce noise at the first point of electrical contact with component power supplies. No power conditioner 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, Sigma power cords function as independent, high-current power conditioners.
“Shunyata continues to push the state-of-the-art in AC power. The Sigma is the best cord Shunyata has made, improving on previous models by deepening background silences , increasing resolution at the lowest levels, rendering textures more realistically, allowing the rest of your components to sound their best. Robert Harley’s reference.”
