IFI iPurifier2 (Accessories)

The USB transmission standard was not designed for high-quality audio: audio/power/ground are all lumped into one cable for printers, hard-disk drives and the like. In the pursuit of the highest-quality of USB audio playback, this is akin to placing dedicated audio interconnects and high-current power cables together, which is clearly far from ideal.

Electro Magnetic Compatibility (EMC) issues inevitably arise, characterised by a harsh, edgy sound.

The iPurifier does one job and one job only; it cleans and filters audio + power at the end of the digital chain; just prior to the digital signal entering the DAC .

The specially-designed circuit restores the signal waveform and puts the analogue back into USB audio for a true, life-like presentation.

Future-proofed, it is able to handle high-resolution PCM/DSD and DXD at all levels. A: all DACs gain a sonic uplift.

Technologies:
PurePurification technology removes unwanted EMI from USB audio + power.
iPurifier removes DC offset and rebalances the USB audio for perfect transmission.
Compliant with USB Audio Class 2.0 (handles PCM/DXD/DSD).
