iFi Audio SupaNova

iFi Audio’s SupaNova active power cable equals clearer audio – the multi-faceted active power cable eradicates noise from dirty mains power and adds clarity to your favourite sounds. iFi’s new SilentPower range tackles mains-related noise to improve audio/AV system performance.

iFi have made a number of ‘clean power’ products to date, but they've never made a specialist IEC power cable for home audio components – until now! The SupaNova is a specialised 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.

Two pairs of live and neutral conductors are arranged either side of the earth conductor, which is positioned at the centre of the cable. A further pair of air-dielectric delineators – essentially polymer matrix tubes filled with air – are arranged either side of the earth conductor, keeping the two pairs of live and neutral conductors apart whilst improving the cable’s overall dielectric performance and constructive solidity.

The Cable
The SupaNova incorporates five conductors, each made from heavy-gauge, continuous-cast OFHC (Oxygen-Free High Thermal Conductivity) copper, arranged in a geometrically balanced configuration – highly unusual at such a price point. The cable is finished with a tough yet flexible polymer outer sheath and iFi’s bespoke audiophile-grade connectors, complete with 24ct gold plated oxygen-free copper conductors.

Power Conditioning Activated!
The SupaNova takes the Nova and adds a cylindrical housing partway down its length. This contains iFi’s proprietary Active Noise Cancellation II technology. ANC II actively eliminates far more noise across the frequency range than a passive product, even across the lower frequencies. iFi use inverse noise current to cancel out the noise in the mains signal. The way this works is comparable to the technology in noise-cancelling headphones.

Ground Zero
Two pairs of live and neutral conductors are arranged either side of the earth conductor, which is positioned at the centre of the cable. The ground conductor is arranged in a shotgun configuration and not twisted around like other mains cables. The live and neutral conductors are arranged in a truly balanced configuration; hence their magnetic fields cancel each other out perfectly.

a Do-it-all Active Power Cable
By combining Nova’s sophisticated construction with Active Noise Cancellation II, the SupaNova has become a ‘do-it-all’ clean-power cable solution that delivers optimised power to individual audio/AV system components without the need for a separate mains conditioning device. Sonic improvements delivered by the SupaNova power cable include greater clarity and definition, plus enhanced dynamic, and spatial qualities, avoiding the apparent softening of leading edges, timing and dynamics that can occur with lesser mains filtering products.
