The USB audio platform is well-established, yet as with any audio transmission protocol, unwanted factors hinder the audio quality. iFi’s obsession with ‘cleaning up’ the USB audio chain drawn from the knowledge base of AMR. As early as 2012, iFi invented the first USB power regenerator – the iUSB Power. This was swiftly followed by professional USB audio cables – the Mercury and Gemini. Later came the USB audio filter – the original iPurifier. Fast-forward to 2015 and we now have the iPurifier 2.
Most effective at the end (rather than the beginning) of the ‘digital USB audio chain’ the iPurifier 2 cleans up the USB transmission. There is an iPurifier 2 perfectly suited to every DAC.
