iFi audio SilentPower SupaNova 1,8 m Hi-Fi Power Supply

The SilentPower SupaNova is an active IEC power cable that delivers cleaner mains electricity to hi-fi and AV components. It combines concurrent shielding, Active Noise Cancellation II, and Ground Zero geometry to suppress EMI/RFI and mains-borne noise, while built-in surge protection guards connected equipment. At 1.8 m long, it slots between a wall outlet and any IEC-equipped source, amp, or DAC without needing a separate power conditioner.

• Active Noise Cancellation II — circuitry built into a cylindrical housing mid-cable that actively cancels mains-borne noise across live, neutral, and earth.
• Concurrent shielding on individual power lines for constant impedance and EMI/RFI rejection.
• Ground Zero geometry with central ground conductor for balanced noise rejection.
• Surge protection: 10,000A at 775V — guards connected equipment against spikes on the mains.
