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 far from ideal.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.
PurePurification® technology removes unwanted EMI from USB audio + power.
iPurifier removes DC offset and rebalances the USB audio for perfect transmission.

I purchased two of IFI Audio Purifier. Not sure of the science behind these little devices but they certainly improved the sound quality on both my systems.
