iFi Audio SupaNova - 1.8m

iFi’s new active power cable equals clearer audio.

Our multi-faceted active power cable eradicates noise from dirty mains power and adds clarity to your favourite sounds.

The sound of SilentPower.

iFi’s new SilentPower range tackles mains-related noise to improve audio/AV system performance.

We have made a number of ‘clean power’ products in our nine-year history to date, but we’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.

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.

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 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.

Ground Zero

As already mentioned, 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.

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.

As a result, there is no residual magnetic field being applied to the centre-ground conductor, and no unwanted induced voltage on the Ground conductor – we call this design Ground Zero.

Power conditioning activated!

The SupaNova takes the Nova and adds a cylindrical housing partway down its length. This contains our 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. We 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.

The SupaNova also includes:

Our Wireless Purification System to significantly reduce power-line noise without audible or visible side-effects

A Ground/Earth connection diagnostic

Polarity detection to ensure correct polarity at all times

Over-voltage Surge Protection, an auto-detection and cut-off circuit to protect your equipment
