The good news is that it is ready for all present and all future PCM, DSD and DXD files without restriction. Your music is safe, sound and future-proofed.
Loving your computer audio set-up but got annoying system and power noise?
Let the iPurifier3 improve your USB audio playback experience.
Gremlins beware
Computer audio often comes with annoying noise and jitter.
The iPurifier3 is for anyone into USB audio who regularly battles with these irritating audio gremlins.
Never fear, let the iPurifier3 be your system’s white knight.
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. Both Type A and B are available.
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.
It will improve your USB audio playback experience faster than you can say King Arthur and the Round Table.
Enjoy the silence! Our Active Noise Cancellation II® (ANC II) tech means that measured noise drops by 100x or 40dB in comparison to the common noise filter.
Tantalum capacitors are another example of the top-notch components we prefer. These polarised electrolytic capacitors have superior frequency and stability characteristics, giving them a super high volumetric efficiency.
iFi always uses the best components possible. These OS-CON™ capacitors provide excellent noise reduction and have a long life span. They are not often found in products costing <US$1000.

REclock2, REgenerate2, REbalance2® – cleaner, clearer music. The 2nd generation of this technology creates an all new signal, eliminates computer jitter and removes noise contamination to restore a ‘balanced’ signal.
This excellent copper-alloy EMI shielding isolates devices and cables to block radio frequency electromagnetic radiation.
Vishay MELF resistors – complex, costly but superior.
These metal electrode leadless face resistors have excellent accuracy, stability, reliability, and pulse load capability. They provide optimal power rating and pulse load capability. Nothing else comes close.

It’s ‘i-fi’ and not iffy at all!
“…considering the modest price I consider it to be a bargain and a very worthwhile addition to my hifi.”

It works!
I was not sure how much this device could improve my system. Components are as follows: Sotm SMS200 network bridge, Chord 2Qute dac, Little Dot mkV headphone amp and Monoprice modern retro headphones. Apart from the headphones, this is not a cheap system and each component is generally highly respected. The SMS200 filters it’s USB output and the Chord galvanically isolates it’s USB input. So what could the ifi possibly do to improve the signal. Much more that I expected is the answer. Some reviews mentioned the character of their sound was altered and I don’t know if the comments were meant in a good or bad way.
I my case it’s all good. On playing the first track I immediately noticed the volume seemed to have increased. I suspect this is one of the benefits of the reduction in digital noise or hash, as it’s often described. Other benefits are noticeable silence in the background, expanded sound stage, greater separation between instruments and vocals and much more detail than I knew existed. That is my experience with my equipment so I can’t say everyone will hear the same. To my ears this is a worthwhile upgrade.

This thing does sound really good. Great improvement for the money.
I was not a fan of the AudioQuest Jitterbug, but the iPurifier 3 sounds great in my system with few drawbacks. The main changes are a greatly increased dynamic range (it’s a bit mysterious why this would be, but ok) and removal of high frequency and midrange graininess.
There is a tiny bit of haze introduced, and for some the sound might be a bit too dark and smooth because the loss of noise, but on the whole it is pretty big net improvement. The increase in dynamics alone is pretty wild.

Review: iFi iPurifier 3 – lower noise on a budget
“iFi iPurifer 3 gets you a lower noise floor, more space, less ringing and more clarity in your music.”

Very good
Like many I was skeptical about the usefulness of the device but the results are there, and they are blatant. I am still convinced that with a good computer and a good dac, this device should be useless, but apparently it was not the case with me despite very good equipment.
Obviously once you’ve tasted it, you can’t do without it

Phenomenal!
I recently bought the isilencer 3.0 from the same brand. This brought so much to my GD NFB 29H audio that I wanted to try the more advanced version of the system from IFI.
Although I took it, it’s breathtaking! The bad news is that it’s even better using the isilencer 3.0 at the PC output and the Ipurifier 3 at the DAC input. It’s better but it’s more expensive … But the investment is really relevant. Timbres, dynamics, rhythm, harmonics, reverbs, depth, etc., we win on all fronts. Expensive but ultimately in terms of the result, it is an excellent investment.

USB Audio
USB audio is a digital audio connection used to send digital music from your computer to a digital to analogue converter (DAC). Usually computer manufacturers spend most of the overall budget on the processors and screen, leaving minimal budget for the built-in DAC and audio outputs.

Active Noise Cancellation
Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.
Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.
Common Noise Filter
The common noise filter cuts out most noise gremlins found in typical audio systems such as RFI/EMI.
File formats
MP3 – this is the most popular format, every device in the world can use it.
DSD – Direct Stream Digital is a very high-quality audio format, better than CD quality. The higher the number (sample rate), the better the recording – DSD64, 128, 256, 512 and 1024.
PCM – Pulse Code Modulation is the most common format for CDs and DVDs.
DXD – Digital eXtreme Definition is a very high-quality PCM format. It was developed to edit hi-res (high quality) recordings recorded in DSD.
Volumetric Efficiency
In electronics, volumetric efficiency quantifies the performance of some electronic function per unit volume, usually in as small a space as possible.
Pulse Load
A ‘load’ refers to a current drain that is applied to a battery. For example, charging the flash in a camera. The term ‘Pulse Load’ indicates that the load is automatically applied for a specific period of time, then disconnected without user intervention.
EMI (Electromagnetic Interference)
EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.
