iFi Audio - SuperQuasar Geometrically Balanced Power Cable with Active Noise Cancellation - Black

The Quasar power cable is engineered with heavy oxygen-free copper to deliver outstanding conductivity, paired with an impact-resistant polymer casing that ensures long-term durability in demanding systems. Gold-plated pure copper terminations maximize current transfer, while shielded power lines and concurrent shielding reduce EMI and RFI for cleaner electricity. A moisture-resistant, low-dielectric polymer matrix and air-dielectric geometry maintain precise signal separation. The true balanced, geometrically matched conductors cancel magnetic fields, and a dedicated shotgun ground minimizes ground-loop noise. Its Ground Zero core design eliminates stray magnetic influence, resulting in exceptional sonic clarity and a class-leading performance-to-price ratio for refined yet affordable audio and AV systems. It is an ideal foundation for listeners seeking neutrality, dynamics, and reliability without excess cost.

A non-technical analogy for this might be that if you drop a coin in a tube with shampoo in it, no matter how wide (low resistance) that tube, the shampoo (the Characteristic Impedance) is going to get in the way (compromise current transients). Eliminating Characteristic Impedance (Zero means No in this application) is like having only air in the tube, as close to a vacuum as possible. Whether the amp is running at less than a watt or is fully maxed out, the unrestricted transients are visceral — something the whole body understands, no words required.

iFi’s new SilentPower range tackles mains-related noise to improve audio/AV system performance. They have made a number of ‘clean power’ products in our nine-year history to date, but they’ve never made a specialist IEC power cable for home audio components – until now! The SupaNova is a specialized active power cable with a high-end construction that belies its affordable price point. It delivers a serious upgrade over standard mains leads that imbues sound with greater clarity, space and definition.
