iFi’s Audio’s AC iPurifier is a small, cylindrical, plug-in mini-power conditioner that plugs directly into AC outlets. Each AC iPurifier uses iFi’s distinctive Active Noise Cancellation circuitry. The AC iPurifier can detect polarity and/or earthing problems. There is also a 4mm banana-socket for adding supplemental earthing wires if desired. Finally, the AC iPurifier provides surge suppression to a maximum of 30,000A @ 1,000V/10ųS.
We were surprised by the nature and magnitude of the sonic improvements the PowerStation/AC iPurifiers wrought. Along with quieter backgrounds, the reviewer felt that, “really significant gains came in the form of deeper levels of textural and transient details.” He concluded that, “I recommend the iFi PowerStation and AC iPurifiers for the simple reason that they help unlock more music for less money than other competing power conditioners I have tried. You cannot say fairer than that.”
