The sound of SilentPower. We are introducing the new additions to our SilentPower Range, SupaNova & Nova - Our all-new power cables.

Most power-conditioning products engage passive noise reduction through a selection of filters and regulators. While this can be effective, it has inherent disadvantages. Passive noise reduction systems are effective at the top end of the frequency spectrum but often less so at lower frequencies. In addition, passive systems need large capacitors to be truly effective, which make the best such products bulky and expensive.

iFi’s active system uses inverse noise current to cancel out the noise in the mains signal. Noise in the mains supply occurs at different frequencies, depending on the cause. Active Noise Cancellation II technology enables a power-conditioning device that is highly effective at reducing noise consistently across the entire frequency spectrum yet sufficiently compact and lightweight to position within the mains cable itself.

A few more words about our NOVAs.
The cable 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.

A bit more about the Ground Zero.
As already mentioned, the cable 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.
 
Dear iFi,

I have been using one of your power supplies for over a month now, I am very very very impressed with the performance.

Kindest regards,G.
 
Pardon the lack of clarity on my end. I was referring to the iFi products. I was curious which of the iFi products did you incorporate into your system.

I'd be happy to test out a few Novas here in Auckland New Zealand, if you're interested in user reviews. :)

Hello, what about the conductors used in Nova and Supanova - are they solid core or multistrand?
 
Hi @1GTRBG , the answer is - Multistrand.

They incorporate 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.

Hi, thanks for the reply - will buy 2 Supanova(((•?•)))

Hi IFI Audio, question what do you recommend between supanova and nova as replacement power supply from Elite to power conditioner (Shunyata).
