Alongside its audio devices for home and portable use, iFi makes a range of accessories to tackle common issues that affect the performance of audio systems and their prime objective is to reduce noise in the audio signal which may be engendered in various ways, from problems caused by USB interfaces to issues with mains electricity.
iFi’s latest collection of specialized audio enhancers’ deals specifically with mains-related noise. The all-new SilentPower range consists of four products at launch: the DC Blocker, the GND Defender and a pair of IEC power cables called Nova and SupaNova.
The DC Blocker is a neat, highly effective solution to DC on the mains – a problem well known to affect the performance of audio equipment and a significant cause of irritating transformer hum. The device is capable of canceling more than 1000mV of DC voltage, thereby correcting the DC offset and re-balancing the AC sine wave. Moreover, it does this intelligently – in other words, it adjusts its performance according to the level of DC detected.
If a problematic ground loop exists, the GND Defender resolves the issue by disconnecting the loop running through the connected component. By using one or several GND Defenders in a Hi-Fi system, the user can ensure that all components are connected to a common ground via a single path, eradicating the resulting hum through the speakers.
The Nova mains cable incorporates five conductors, each made from heavy-gauge, continuous-cast OFHC (Oxygen-Free High thermal Conductivity) copper. Two pairs of live and neutral conductors are arranged either side of the grounding (or earth) conductor, which is positioned at the center of the cable. This geometrically balanced configuration causes the magnetic fields generated by the live and neutral conductors to cancel each other out perfectly, ensuring the grounding conductor is unaffected by residual magnetism and unwanted induced voltage – iFi calls this design Ground Zero. A further pair of air-dielectric delineators – 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 SupaNova active power cable takes the Nova and adds a cylindrical housing partway down its length. This cylinder contains Active Noise Cancellation II – the latest version of iFi’s proprietary noise-busting tech – in combination with advance-filtering components. By combining the Nova’s sophisticated construction with Active Noise Cancellation II, iFi says that they offering a do-it-all clean-power cable solution that delivers optimized power to individual audio/AV system components without the need for a separate mains conditioning device.All four devices in the iFi SilentPower range are already available with RRPs: DC Blocker: £129, €149, US$129; GND Defender: £99, €129, US$99; Nova: £169, €199, US$169 (1.8m cable) and SupaNova: £349, €399, US$349 (1.8m cable)
