    Thanks for all the answers! One last question: you wrote me that star wiring partially defeats the operation of the ipurifier. So, is it a good idea to open the very thick Kemp power cable before it reaches the power strip to place one or two ipurifier in a wall outlet? I could do this in the neighbourhood of my house installation.

    iPurifier AC creates a "point sink" for noise, precisely where it is plugged in. Noise will be reduced at this point regardless of source thus it acts as a "gate". Noise on one side is reduced passing to the other side.

    The amount of noise reduction depends on local mains circuit impedances. The thinner and longer the cable, the higher the impedance the iPurifier AC works "against" thus the greater the benefit is.

    It must be noted that SMPS type power supplies typically include large values of chokes for filtering in the mains, so they do not benefit much from long cables, as the difference compared to build in impedance is small.

    So if we want to quiet SMPS noise in a system that mixes this type of PSU with linear, plugging all SMPS powered devices into a separate power strip and one or more iPurifier AC closest to the input side of the strip will "contain" the SMPS noise "within the powerstrip" and prevent it from travelling into the rest of the mains wiring powering the system.

    Equally, if we mainly want to kill noise entering the system from mains system at large, then placing one iPurifier AC or more where we take off separate power for a system will do the most good.

    So, it is important to be clear where the origin of noise we wish to "iPurify" is and place iPurifier AC in a position "in line" with it.

    does the ipurifier protect against power surges if it's next to a power strip, but not on it? (sitting on the top mains power outlet socket and the strip is on the bottom socket) or does the ipurifier need to be on the power strip before the components?

    I see ifi is a UK company, why is it that there isn't a UK version of this and an adapter has to be used?

    Unboxing the AC iPurifier



    This is our AC iPurifier, AKA ‘Noise Terminator’ device which is a simple plug and play product that is positioned either at a walls outlet or in a power strip or combination of both, reducing noise in the power domain locally and wirelessly.

    The above video shows Owen unboxing and viewing the contents of an AC iPurifier.

    Available in 3 options: USA / EU / AUS – though a UK adapter is provided for the UK.

    Check back later for more on the tech...

    Can anybody explain that when I use ifi ac purifier in correct polarity sound is brighter but in reverse polarity the sound is lot warmer . The effect is not even subtle specially with 4 such units . All my units are of two pin except one which is with earth pin also. Due to wiring at my home three pin version is always in reverse polarity. Why it is happening ?

    Hi there,
    We will struggle to give a more informative reply as some countries have balanced power to begin with. We need to know the full system context too. Without asking for you to divulge too much personal information publicly here, open a support ticket and we can keep any info you give to us private. Please open a support ticket at https://support.ifi-audio.com/ and we'll get to you asap.
    Thanks
    iFi

    @iFi audio does balanced power have any benefits, and does it impact where to put the ac purifier in a extension outlet?
