iFi Audio iPurifier3 - USB Purifier
The iPurifier3 delivers a comprehensive USB signal quality solution. From common electrical, protocol, data to EMI/RFI issues, the iPurifier3 solves them all, in one, thumb-sized design.
The iPurifier3 re-equalises unbalanced USB signals for an improved audio data stream and re-clocks, re-generates and repeates the USB audio data stream. The iPurifier3 simultaneously reduces the USB power supply noise by more than 100 times.
Features
- REclock, REgenerate repeats the USB signal, eliminates USB jitter, frame and packet noise and restores USB signal integrity
- REbalance corrects USB signal balance and impedance mismatch
- Upgraded Active Noise Cancellation (ANC) military-grade circuit, which now has a wider operation band and reduces USB port audio band noise even further
- New OS-CON and Tantalum capacitors for extra power filtering and smoothing
- New high-precision MELF resistors for improved accuracy and stability
- New gold-plated copper-alloy shielding to reduce EMI interference
- USB Audio Class 2.0 (supports all formats)
Active Noise Cancellation® drawn from military radar technology
Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation (ANC) audio power system. It is now a cornerstone of the ever-improving iFi USB audio technology, looking for new products to feature ANC，and ANC+. An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an on board system to cancel out the enemy radar signal. By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC is the perfect ‘antidote’ for power supply noise, the bane of USB audio. ANC measured, noise drops by 100 times or 40dB in comparison to the Common Noise Filter. Sonically, the background and inner resolution to recordings is enhanced several levels.
REclock reclock/regenerate/repeat the signal
Re-clocking is beneficial to audio. REclock is a ‘3-in-1’ feature that re-clocks/re-generates/repeats USB audio datastream. For any and every downstream DAC, REclock technology eliminates jitter. Music flows better, is cleaner, deeper and tauter, just like the real thing.
REbalance rectify the unbalanced signal
A core element of the original iPurifier’s success was REbalance which has naturally been carried over to the iPurifier 2. By removing the DC offset and ‘re-balancing’ the USB audio signal, it is now perfectly balanced. As it purifies the USB audio data stream, this means noise is significantly reduced:

On day 2, it still sounded distorted. On day three, it sounded normal—no better, no worse. Over the next few days, I thought I noticed better focus on the sound. On a particular album where the artist speaks into the microphone between songs, I noticed an obviously reduced boominess and less spottiness. It was a definite improvement that stood out to me. However, trying that again just now with a quick A/B, I could no longer perceive the difference.
I think the interference from which this is supposed to isolate the DAC will be a moving target, worse some days than others. After about 40 hours of use, I think the sound is a little clearer, less bloated, more airy, but perhaps, at times, not as relaxing to listen to.
Why 5 stars? It's well-made, looks nice, and is plug-and-play. It's definitely not doing anything wrong. I'm happy to keep it and am interested to see how it performs after I upgrade to a standalone DAC.
I have a TP-Link switch powered by the iFi Power X. This is connected to a NUC 11 running Roon via a Chord Clearway Streaming cable. A Chord Clearway USB cable with the iPurifier3 on the end connects the NUC to a Cambridge Audio CXA81.
The power supply and cable upgrades made bigger improvements.
It is highly recommended!
After being in my system for a few weeks, I will not be returning this. Going from my computer to a Chord Qutest DAC, the difference it has made is very audible. Mid-range and top-end are a lot clearer and has reduced the sharpness. Bass has become more refined and deeper. It is a very inexpensive but effective upgrade for the price that it is.
Thank you for your great advice and service.
