Surge Protectors & Extension Leads iFi

The SilentPower SupaQuasar active power cable is engineered to deliver exceptionally clean, stable power for high-performance audio systems. Its True Geometrically Balanced Ground Zero architecture forms a central magnetic-free core, while Active Noise Cancellation II injects inverse current to suppress interference across live, neutral, and ground lines over the full frequency range. Heavy-gauge OFHC copper conductors ensure ultra-low resistance and optimized current delivery, supported by concurrent individual line shielding, air-dielectric delineators, and constant impedance control to block EMI and RFI. Robust surge protection up to 10,000 A and gold-plated copper connectors housed in a

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 …
