The sound of Silent Power
iFi Audio has made a number of ‘clean power’ products in their nine-year history to date, but one thing they haven’t made is a specialist IEC power cable for home audio components – until now!
The SupaNova is a specialized 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 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.
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:
- iFi's 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
- Noise reduction: > 40dB (> 100x)
- Surge Protection: max. 10,000A @ 775V / 8/20uS
- Under Operating Voltage: Maximum operating rating 10A at 250Vac and 15A at 125Vac
- Length: 1.8 m (70.8")
- Weight: 675 g (1.49 Ibs)
- Warranty period 12 months
