iFi Audio PowerStation and AC iPurifiers

iFi Audio is best known for its several successful families of high-tech and high-value personal audio electronics products, but what is perhaps not so widely recognised is that the firm also make a host of innovative cables, accessories, and power products. This review will focus on two of iFi’s most significant power products: the recently released PowerStation power conditioning and power distribution module (£499, $499 US) and the firm’s clever, modular AC iPurifier devices (£99, $99 US, each). Let’s start with the AC iPurifier.

iFi’s AC iPurifier is a small, cylindrical, plug-in mini-power conditioner that plugs directly into AC outlets. Versions are available for use with UK (via adaptor), EU, and US AC sockets. Each AC iPurifier uses iFi’s distinctive Active Noise Cancellation circuitry, says iFi, to reduce noise on the AC mains and “to rid your system of electromagnetic interference (EMI) or radio-frequency interf­erence (RFI).” Further, the AC iPurifier can detect polarity and/or earthing problems, which are shown via two multicolour 'go/no go' indicator lights mounted on the face of the unit (green means go, while red means trouble). There is also a 4mm banana-sock for purposed of adding supplemental earthing wires if desired. Finally, the AC iPurifier provides surge suppression to a maximum of 30,000A @ 1,000V/10ųS.

Basically the PowerStation leverages more expansive versions of the noise reduction technologies found in the AC iPurifier. The PowerStation looks like a cross between an oversized conventional AC power strip and a stealth fighter as it sports an angular, matt grey-anodised aluminium enclosure with multiple AC outlets on top and a wedge-shaped 'nose' on one end. Japanese and US-specification units provide eight AC outlets, while UK, EU, and AU versions offer six outlets. A device that looks much like an AC iPurifier protrudes from a recess in the wedge-shaped nose of the unit, complete with its own set of 'go/no go' polarity and earthing indicator lights, plus a banana socket for supplemental earthing. The opposite, squared-off end of the PowerStation provides a power switch and an IEC inlet for the unit’s primary mains cord.
