Active Noise Cancellation®

The USB audio
‘Grand Slam’





iFi USB audio technology
is unsurpassed


100 times reduction in noise

micro iUSB + Gemini
+ iPurifier 2

The USB audio platform is well-established, yet as with any audio transmission protocol, unwanted factors hinder the audio quality. iFi’s obsession with ‘cleaning up’ the USB audio chain drawn from the knowledge base of AMR. As early as 2012, iFi invented the first USB power regenerator – the iUSB Power. This was swiftly followed by professional USB audio cables – the Mercury and Gemini. Later came the USB audio filter – the original iPurifier. Fast-forward to 2015 and we now have the iPurifier 2.

Most effective at the end (rather than the beginning) of the ‘digital USB audio chain’ the iPurifier 2 cleans up the USB transmission. There is an iPurifier 2 perfectly suited to every DAC.

All-new and cutting-edge.


In an all aircraft-grade CNC-aluminium shell anodised in ‘titanium’,the all-new iPurifier 2 features the very latest USB audio technology from Active Noise Cancellation® to REclock® and REgenerate®, whilst still retaining the original REbalance®.

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:


Future-proofed. Like no other

LOGO ver1 8

At iFi, we already develop cutting-edge, advanced audio converters from AMR trickle-down technology. Given this pedigree, the iPurifier 2 (just like the original iPurifier) is ready for all present and future PCM/DSD/DXD formats – without restriction.

So your iPurifier 2 will improve your USB audio playback experience for many years to come.

The iFi ‘Grand Slam’. Nobody does it better.

iPurifier2+iUSB+Gemini_2To reach the absolute zenith in USB audio quality, iFi loves to push past the envelope of what is considered possible. We recommend the existing iUSB Power (to supply pure, clean power) and the Gemini cable (for separate audio + power transmission). Coupled with the iPurifier 2 to re-clock/regenerate and filter audio+power just prior to entering the iUSB Power (in this instance, not at the DAC end).

For the iUSB3.0, that alone incorporates all that we have learnt over the past few years so the iPurifier2 is not required to improve the iUSB3.0.

User Manual


iPurifier2: Head-fi user, Turrican2, says: “sorry wallet”!
Pros: Easy to use and cleans up the audio signal nicely
Cons: Makes me want to buy the iUSB Power
“I then added the iPurifier to the chain. Again, I listened to the first few tracks. At first I didn’t really notice too much of a difference, until I got to the second track, Dreams. The splash cymbal at the beginning caught me by surprise a little, it seemed more sustained and cleaner than I remembered. I looped this part of the track a few times, removed the iPurifier and repeated. Sure enough, I can tell the difference pretty easily. After a few hours of listening with the ipurifier attached, I’ve decided it’s staying put in this setup. To my ears it makes a good difference to the general soundstage (width especially) and overall clarity of the sound. I like it! Makes me wonder about adding the iFi iUSB Power to the mix if this little thing can make a decent improvement, who knows what that will do……sorry wallet.”

“grabs the hammer to kill your piggy bank”
“The iPurifier2 similar to the ‘old’ iPurifier, but does considerably more than its predecessor…..For starters took, both Harmen Fraanje as Bob Dylan, the spatial representation considerably in size. The image became especially forward and in width, a lot bigger. Tone colors were intense and the dynamics increased. ”

iPurifier2: “I could not believe it. The difference was immense”
“The iPurifier2 lies before me in the USB-B version and is compatible with USB 2 and USB 3…..REbalance®, the ability to correct a DC voltage zero crossing error, we know from the predecessor.REclock® and REgenerate® designate the jitter-eliminating process of signal processing. That the exemption from jitter improves the sound, is known. Active Noise Cancellation® serves to suppress the electromagnetic interference and radio frequency interference. This is done by means of an active circuit made of radar-military technology….The hearing test I started with three songs in PCM in high resolution over the Audirvana plus player from my Mac Mini: namely Supertramps “School,” Getz / Gilberto “Girl From Ipanema” and Krall’s “All Or Nothing At All”. At the very first title, “School”, I could not believe it. The difference was immense, to such an extent as I was not expecting it. Without the iPurifier2 it sounded punchy and bold with great spatial depth. With his presentation gained considerable spatial arrangement and clarity. The striking-scale, superficially punchy sound was lost in favor of a great presence of the band. Instruments and vocals were isolated, less intertwined and seemed grippy…..For those who do not like to invest in expensive cable USB, the iPurifier2 may be the golden path.”
Dankeschön Wolfgang Kemper and WOD Audio (iFi:Germany)!
