iFi Audio iPurifier 2 - USB Purifier

 

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

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.

To 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.

Home audio lines with clear names

The ZEN series includes the ZEN Air DAC, ZEN DAC, ZEN CAN, ZEN Phono and ZEN Stream. The iDSD series includes the Valkyrie, Phantom and Diablo, and the NEO range includes the NEO iDSD and NEO Stream. The iCAN Phantom and the Hip-dac sit alongside them.

Portable products for your phone or laptop

The GO series covers the GO pod, GO link, GO bar and GO blu, which are small units for phones and laptops. Larger portable models include the xDSD Gryphon. Bluetooth and USB-C versions mean you can choose the connection that matches the device you already own.

Cables and adapters complete the catalogue

iFi lists digital cables, audio cables and adapters in its accessories range, including the GO cable. These are the parts that link an iFi unit to the rest of your system, so you can pick up the right lead from the same brand when you buy the DAC or amplifier.

Why we stock iFi

iFi solve specific problems rather than selling you a whole system. Noise on a USB feed, a laptop that cannot drive your headphones properly, hum from a ground loop. Each unit does one job well at a price that does not require a long think, which is why they turn up in so many systems.

I could hear no discernable diffence 13 August 2020
Bought one of these from Futureshop but returned without any hassle as I could not hear any discernable improvement in my system. Not saying it will not work for others but it did nothing for me.
Igor ✓ Verified Purchase
Small device, but realy marvellous one 14 December 2017
Clear, pure sound, tight bass and crispy treble. Much better than before. I use it with iFi Nano iDSD - ideal coupling.
Highly recommended. I am really happy with this modification.
Alastair ✓ Verified Purchase
Excellent Product 30 November 2017
I primarily bought this as I was having annoying jitter problems causing dropouts on two different computer sources when feeding my Audiolab DAC. Possibly, an iSilencer or Jitterbug may have cured this without reclocking, but as others describe, the iPurifier also brings a substantial sonic improvement with more detail and refinement.
