Description
iFi audio was launched in 2012 and its ultra high-end pedigree dates back a decade further because of its parent company: Abbingdon Music Research (AMR) which produces expensive luxury audio products. AMR saw in 2010 that hi-fi audio was shifting from home ‘static’ speaker systems to Bluetooth and portable ‘dynamic’ headphone setups To serve this growing market, iFi audio was commissioned with one goal: to produce ‘ultra-fidelity’ audio products that push the sonic performance at the envelope while still priced within the mainstream. It began work on a range of small but prodigious personal audio products using AMR’s trickle-down technology. Today, iFi designs and manufactures over 35 different products from its headquarters in Southport, UK. It sources parts from around the world from manufacturers including XMOS (UK), GE Valves (USA), WIMA (Germany) and TDK (Japan). It retails through a global network of dealers and has its own distribution in the USA who serves retailers such as B&H and etailz. There are more than a few AC clean-up devices that add an extra Ground/Earth but only the AC iPurifier has ‘Intelligent Ground’. You can buy the optional extra 4mm ground cable to give the audio system the best possible Ground/Earth but it will ONLY actively provide a Ground/Earth (if it detects the lack of one*. It will not create a ground loop). When it comes to mains AC, there are two common errors which people can make when setting up a system. The first has to do with polarity and the incorrect orientation of USA and EU type mains pins. Intelligent Polarity automatically informs you of incorrect orientation by changing to a red LED. The second error is the a lack of Ground/Earth. In a system where there may or may not be a lack of a Ground/Earth, simply insert the AC iPurifier into the system and it will tell you one way or the other. When the two LEDs light up green everything is in order! For the rare instances where there is an overvoltage spike (from a mains electricity surge or lightning strike for example), the AC iPurifier will automatically shut off and stop electricity from passing through your system. This should protect your valuable and highly-sensitive mains equipment from harm. This chart compares the AC iPurifier (green line), which is ACTIVE, versus generic mains filters (red line) which are typically passive. The effective noise reduction difference is much better at -40dB and effective across the frequency range. A passive purifier filters only in the very top-end of the frequency range. By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+ is the perfect ‘antidote’ for power supply noise, the bane of USB audio. The AC iPurifier is the latest product to have onboard ANC. As its name suggests, it ACTIVELY cancels the noise which makes it one of the power accessories, if not the only one, that actively cancels noise. With many modern audio systems, there are typically a plethora of mains plugs. All of these add their own unwanted noise issues and pollute the local mains supply. The design of the AC iPurifier is such that it is even more effective if several are used to ‘contain’ the same type of noisy sources. You can insert into the AC mains wall outlet that supplies the audio system OR insert into the mains extension block for the audio system. Try both locations to discover which has the greatest impact on improved sonics.
