iFi Audio iPurifier3 - USB Audio and Data Signal Filter - USB-B

The White Knight
The third generation and slightly larger reincarnation of the iPurifier measures just 69 x 19 x 20mm in its new, dashing white armour. It uses iFi Active Noise Cancellation2 tech to decrease noise by 100x or -40dB in comparison to the common noise filter.

REclock, REgenerate, REbalance
Our state-of-the-art REclock, REgenarate and REbalance2 technology will get your audio back on track. Put simply, it actively ‘restores’ the USB audio+power streams which eliminates jitter and ensures smooth passage for your music. REbalance® actually removes distortion caused by DC offset.

Dashing. Durable.
The iPurifier3 is set up for all future PCM, DSD and DXD formats. And it’s not just better looking on the outside, it’s been improved on the inside with updated components. No need to worry about upgrading for years to come.

Active Noise Cancellation II
The iPurifier3 has a further optimised version of its much-acclaimed and award-winning ANC2® system adapted from military radar defence technology. Emulating the way in which air defence radar technology works, iPurifier3 identifies noise frequencies then generates identical but opposite frequencies, which actively cancel all incoming noise.
