Ifi ipurifiEr3 usB
The ifi IPurifier 3 is a device that claims to remove any d.c. offset voltage that might be present in a USB voltage and also re-clock and re-generate the USB audio data stream to eliminate jitter.
‘ iFi developed the first USB power regenerator, the iUSB Power, in 2012, then followed up with the original iPurifier, followed in 2015 by the iPurifier2 and now the iPurifier3,’ said George Poutakidis, of BusiSoft, which distributes iFi in Australia. ‘ The iPurifier3 uses iFi’s ANC2 circuitry to identify noise frequencies then generate identical but opposite frequencies to actively cancel unwanted noise. Compared to an ordinary noise filter, ANC2 decreases noise by 100 times, thereby enhancing the fidelity of background and the inner resolution of audio recordings by several levels.’ The ifi iPurifier3 is available with USB Type A inputs and outputs and with USB Type B inputs and outputs. Both models sell for $169.95 (RRP).
