Features & Specs
Active Noise Cancellation 2 (ANC2) for full-spectrum mains noise reduction
Actively counteracts noise on live, neutral, and earth to help lower the noise floor feeding your components, improving clarity and perceived “blackness” between notes.
Extremely low resistance for maximum current delivery
Designed to minimize resistance so amplifiers and high-draw components can respond faster to transient demands, supporting punch, slam, and effortless macrodynamics.
Geometrically balanced design for cleaner power transfer
A true balanced geometry helps stabilize the cable’s electrical behavior, supporting consistent delivery and reducing the chance of noise masking low-level detail.
Ground Zero architecture to reduce magnetic-field interference
Creates a central core intended to be free of magnetic fields, helping reduce interference that can subtly degrade resolution and separation.
Premium OFHC copper conductors with gold-plated copper connectors
Heavy continuous-cast OFHC copper supports conductivity, while gold-plated copper connectors help maintain a secure, high-quality contact over time.
Integrated surge protection and robust current ratings
Adds an extra layer of protection and confidence for your system, with specified surge performance and clearly defined operating/socket/cable ratings.
