iFi Audio SupaQuasar is an endgame power cable for your audio setup. It has no shielding to minimise capacitance, extremely low resistance to maximum current delivery, and is specifically designed for large amplifiers.
Featuring our Active Noise Cancellation 2 technology, it actively eliminates noise across all frequency ranges across live, neutral and earth. Plus the SupaQuasar active power cable is truly geometrically balanced, a first in the world of power cables.
The cable is insulated using a polymer matrix, which is comprised of a high-performing thermoplastic that is moisture-resistant and is RoHS compliant. Continuing the true balanced theme, the cable uses air-dielectric delineation to give the best separation possible between the two balanced pairs of live and neutral conductors.
Using iFi’s unique Ground Zero design technology, the SupaQuasar active power cable creates a central core that is free of any magnetic fields. The non-twisted central ground wire is surrounded by the live and the neutral conductors as a geometrically-balanced pair double helix which protects the ground wire from any magnetic field. No induction voltage is created in the ground wire and therefore system ground noise is vastly reduced.
Each individual power line has concurrent shielding, so both internal and external RFI noises are minimised. Low inductance, low capacitance and constant impedance are achieved for the entire cable by the use of the double helix power lines. Constant impedance is achieved regardless of whether the cable is bent or angled, thanks to the fully symmetric and balanced geometric design.
iFi uses the purest copper core to ensure excellent conductivity and our plugs are gold-plated with copper connectors to guarantee the best possible connection. Finally, the SupaQuasar active power cable is finished in an impact resistant polymer casing for long-lasting durability
iFi’s active system uses inverse noise current to cancel out the noise in the mains signal. Noise in the mains supply occurs at different frequencies, depending on the cause. Active Noise Cancellation II technology enables a power-conditioning device that is highly effective at reducing noise consistently across the entire frequency spectrum yet sufficiently compact and lightweight to position within the mains cable itself.
