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.
