The iFi obsession with cleaning up the USB audio chain continues. Drawing from the knowledge pool of AMR and on the heels of the iUSB3.0 comes the iPurifier2. It is an Asynchronous Active USB Purifier Hub. It offers 100X to 100,000X noise reduction for USB Power, underpinned by REclock®, REgenerate® and REbalance®. It is so intelligent, it is an active USB hub so it can extend USB lengths. Used at the end of the chain, just select the type A, B , C or micro USB connector version to enhance any and every USB audio device.
• Active Noise Cancellation® military-grade circuit for 100X to 100,000X noise reduction• REgenerate® and REclock® asynchronous technology to eliminate jitter• REbalance® re-corrects USB signal balance to cancel DC offset noise• Compliant with USB Audio Class 2.0 for DSD/PCM/DXD formats (to 768kHz and beyond)• Aluminium aircraft-grade ‘Final’ connector (impedance 90 ohms)
Important note. This product sounded awful at start in my system. I mean really bright and it made me fatigue. There where a lack of bass, and that made it sound overly focused on the higher frequecies. After about 6 hours the sound started to get a lot better with fuller and deeper sound. It will still take another 150 hours to really open up, but then the soundstage gets wide and deep. The details are fantastic, more control. Strange this experience, so my advice would be to wait with critical listening for at least 30 hours. Now I am trilled with the results in my system!

I added the iPurifier between my modestly spec'd laptop and a mid-range DAC (Audiolab M-DAC+). With classical music, high percussion was much more present, violins had a luxurious sheen, and drums and basses had great heft. Detail is greatly enhanced -- perhaps too much for some tastes, though I love it. For the price of an interconnect, this is a no-brainer.
