“Trust me, these Thorsten Loesch bobs of noise trickery make an easily audible difference.”

I was honestly skeptical of the iFI iPurifier3 as most people in the audiophile community call products like this “snake oil” or a scam. But after plugging this into my source chain. It has made a SIGNIFICANT difference. The blacker background, vocal clarity, instrument separation, dynamics has all improved because of this little device.

Listening to some EDM tracks I couldn’t help but sit there and focus on all the details that I haven’t heard before. It presents it in a much more articulate, clearer fashion. I had to make sure that it was because of the iPurifier that was causing this improvement so I A/B’ed with it attached to my DAC and without it. And without it, the music sounds very congested and vocals are a bit subdued. It doesn’t brighten any aspect but just makes it a more clear, cohesive sound.

Trust me, I bought this through Amazon just in case that it was in fact snake oil, I’d send it back in a heartbeat. But no way am I sending this back. I recommend this for those who have a noisy PC, because I had no idea how noisy my gaming rig was. It has made the most difference out of any component that I have added to my chain. And I have upgraded just about everything. Truly amazing product, definitely recommend.

“I know computer USB ports are noisy. But I didn’t know how much the port noise was able to degrade the sound, until I inserted this little noise-remover between the USB cable and the DAC. The change in sound quality was immediately noticeable as the background became darker and the sound stage fuller. The sound should be better in another week or two when the breaking-in settles.”

This well built device plugged between your USB (2.0 or 3.0) cable and your DAC. The idea is to eliminate any jitters or digital noise (if any) and it does the job well. I also recommend to use it with iSilencer+ to complete the source end as well. Highly recommended!

Does it’s job. PC produces better sound than before via usb.

“…considering the modest price I consider it to be a bargain and a very worthwhile addition to my hifi.”

Bought it on spec and half expecting to return it but it’s a keeper. It now sits between an Auralic G1 streamer and Chord M-Scaler – Chord Hugo TT2. The Auralic has high quality dual master usb clock circuitry and the Chord have galvanic isolation + very sophisticated clocking electronics; however, this little gizmo cleans up digital excesses just a little further. The sonic outcome is quite subtle but also immediately noticeable; occasional vocal hardness has been ameliorated, bass is better behaved. The overall result is that of a slightly more organic and “analog” presentation; however, don’t expect a significant transformation in overall sound quality but considering the modest price I consider it to be a bargain and a very worthwhile addition to my hifi.

I Have a collection of Headphones that I love and sound great by themselves and I added the ifi audio zen dac with some audiophile cable’s it sounds amazing and then I decided to add to my already good sound ifi audio iPurifier3. WOW!!!

“Sound-wise, the iFi Purifier is definitely NOT snake oil. What I noticed – and it’s not my imagination – is that some of the higher frequency “grundge” was no longer there. In addition, something happened with the bass that I was not prepared for, and that was the bottom end (or what your speakers can handle) was a bit more defined and tight – now that was a stunner for lack of a better description.

Some of the orchestral pieces that I enjoyed listening to (and use as my reference standard for evaluation purposes) now were presented in an even cleaner fashion – with no harsh overtones or harmonics. It was (especially with some orchestra pieces) as if a small yet very distinguishable veil was lifted between you and the orchestra.

All of a sudden I felt more connected with the musical environment. High’s that previously had lots of bite (raspy sounding for example), now were substantially smoothed out, at the same time providing more “air” around the instrumentation. And this leads to a longer listening time without listening fatigue.”

To be honest, despite the glowing reviews of the iFi iPurifier3 USB Filter, I wasn’t expecting too much of an improvement especially compared to the Audioquest Jitterbug but I was intrigued to hear the possible impact of Noise Filtering technology in combination with it reclock, regenerate, and rebalance technology.

Wow, at $129, it is an amazing value and it is sized for portability – although it is still too heavy to be considered as applicable to “on the go” usage.
Currently using it with a Lenovo Thinkpad 430Ts connected to a Musiland Monitor 01 US DAC/Headphone AMP via a PANGEA Audio Premier USB Cable (0.5meter).

Impact was immediately evident. On the most basic level it manifested as a huge increase in volume. I literally had to reduce the volume by over 30% on the master volume and from -4dB to -14dB in the Musiland controller software. Musical and dialogue was much clearer, cleaner, and sharper.

Sound effects such as reverb and echo were clearly defined rather than a fuzzy fusion as were individual instruments within their own space. Once I install it in my main desktop system, then I may write an update for any additional observations. Although this Filter supports USB 3.0, all tests were done on USB 2.0 equipment.

I was hoping it wouldn’t work so I could save myself the money, but unfortunately or should I say fortunately it improved the quality of the audio though my speakers more than I expected.

I tried tricking my girlfriend in a blind test to see if she could figure out when the device was connected and when it wasn’t. She consistently liked the tracks where the device was plugged in.

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.

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.

“iFi iPurifer 3 gets you a lower noise floor, more space, less ringing and more clarity in your music.”

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

Tried it without and was completely surprised by how coloured the sound was. You get better bass and treble an less colour to the sound.
This is into a Roksan K3 DAC.

I bought this, attached it to my USB cable and plugged it in to my Chord DAC. It is amazing.
There is no longer any bloat to the sound from the speakers. Before using this I had to be careful turning the volume up as I knew which notes and sounds would bloat and stand out badly. The sound is now ultra clear and “stays back” at the speakers”. No forced sound at all.

I never noticed any background noise before but I now know what silence means; I can hear way more going on in the music, details coming through from CD’s I have listened to for 30 years. When I listen to music now, it really does sound like I am in the studio with the artists. I can hear the reverb tails on vocals that were hidden before. Singers like Barbra Streisand and Celine Dion no longer have that screechy edge.

The sound is smooth and velvety and finding the sweet spot is so easy. The depth of the soundstage is brilliant, I can hear horns and drums that are way behind the violins. The whole sound is lighter and “free”. I can hear longer fade-outs on songs that I didn’t know existed before. The bass is deeper and thicker in a beautiful way and I find myself tapping my foot all the time where I never used to. I have to check that I am listening in stereo as the soundstage almost envelops me on some songs. Fantastic.

I cannot recommend this enough, even on expensive systems.

IFi products that improve digital DAC USB front end resolution and reduce noise artefacts have been in steady supply for some years. The Purifier 3 is no exception. Except that it now appears through better and higher tolerance components it does delivers a sound that is significantly better, with more low frequency depth, higher resolution clarity enabling congested parts to be heard.

IFi are proving there is still a low cost leverage to be had where digital sound improvement is concerned.
Highly recommended

System components: Benchmark, DAC3L, HPA4 and AHB2 amplifier
Digital feeds: Auralic, Roon, Linn, and Melco.

Bits are bits, but the way in which they are served up to a DAC makes all the difference in the world. Timing is crucial and the iPurifier goes some way towards eliminating issues caused by noisy signals and bad timing.
Prior to installing the product (well, sticking it onto the end of my Wireworld usb cable and plugging the other end into my Pro-ject Audio Pre Box RS Digital) I had suffered the pain caused by a direct connection to my Mac Mini.

Violins were harsh, dense orchestral section were smeared and the highest notes (bells and symbols, for example) had their sound ‘cut short’.

The iPurifier 3 works. It significantly reduces ‘digital nasties’ caused by time smearing (just google it before you rubbish the idea!).

It is NOT as effective as using a dedicated network audio adaptor, such as the Pro-ject Audio Stream Box S2 Ultra, but that costs much more and I wanted to find a more cost effective solution.
Whether the iPurifier works for you is difficult to say. All I know is that for my particular needs and set up, the iPurifier 3 is an almost perfect solution to a nasty problem 🙂

I have Akiko tuning sticks, Audioquest JitterBug, Furutech outlets, PS audio cables, you name it, and all these had been gradual improvements, while this thing just blew my expectations, day and night!

WOW! What an amazing little product. I’ve had excess noise coming from my computer while playing my music for so long it was driving me crazy. I bought the iPurifier3 and the noise has gone! I can now listen to my music calmly and I’m not tearing my hair out with the hissing anymore. For info, I paired this product with iFi’s Mercury cable 3.0, and the sound quality is even more incredible.

These two products have become my most prized possessions as I use my computer a lot and I enjoy listening to music to help me work, but with the added hissing and popping coming from my speakers I was not focusing on my work as well as I could have. Now, no excess noise and extra work! Hurray!

Made a even bigger difference than a jitterbug and the like. Feels solid and well made,.

Buy it, use, it, if you do not hear a clear difference your hearing is damaged. I sue it on many items, including all USB microphones and sound equipment i own… if its USB it gets one of these inline. If you have no idea what it does, it takes a USB cable that has no standards set by anyone, and cleans and reconstructs its signal, so it comes in clean to your systems.

The IFI Purifier really cleaned up the sound from my DAC. Instruments had more presence and with a silent background. I wasn’t expecting the improvement to be this audible.

This made a significant impact on the noise flow of my headphone setup. It completely eliminated noise being picked up from my computer. I would recommend.

Makes a huge difference. both at the office and at home.

1) Potential Game changer for the sound quality of your system.
2) Beautiful Small Device self powered. I like the white colour.
3) Price still reasonable in comparison with other brands
4) Old generation DACs will sound ENGAGING as much as ifi audio DACs. Never heard my Dragonfly v1.2 to sound so good.
5) The best generation of ipurifier technology.

I’m feeding a Rasp Pi 3 with a iPower 5v into Chord Qutest. I know the Qutest has galvanic isolation and was skeptical whether the iPurifier would make a difference, but I’m always looking for any improvement, especially now that this feeds some very transparent speakers (Pendragons). When I put this in the chain and did a few A & B’s, I could find nothing it was changing and was prepared to send back.

But then, as I listened through the evening, I kept finding myself drawn to the DEPTH of the image. This isn’t what I was looking for, so it took me by surprise. I was expecting the sound to be clearer somehow, but that wasn’t it. It’s a spaciousness and depth in my system. Worth a try in yours, easy to send back if it doesn’t do anything.

I used this device with 4 DACs. An HRT Music Streamer 2+ $250, SMSL M8 $250, Focusrite 6i6 2nd gen $250 and a HIFIMEDIY es9018 $100. Ive fine tuned with a lot of things but always felt something was missing in the sound a sort of glare. In all the DACs i have this device has improved the sound. It is both cleaner and smoother the “glare” i get from computer audio is gone. I would highly recommend this device to anyone who has issues with digital glare this thing made a surprisingly improvement in all the devices i’ve tested in tandem with a Wireworld Ultraviolet USB cable.

With the iPurifier2, it did exactly what it was advertised to do and I stand by my review 100%. On the other hand, the iPurifier3… well… the performance… it goes far beyond iFi’s claims! I have spend a good deal of time with high enddevices such as the Soundaware Esther M1 and M1 Pro, Sony’s WM1Z Walkman (my brother still has too much money), the Sennheiser HDV820 (with and without the iPurifier2), and of course the xDSD. I know my headphones. I know my music. I know my gear. To this date, I have never muttered nor typed the words ” I am hearing things in my music I have never heard before! “, yet… I – just – did.

I know what is lurking in your head while you are browsing this and I guess I have answered this in the title. I am using the iPurifier 3 with my iFi Micro Black Label as shown in pictures. The sound from my high resolution music especially DSD and FLACs with high sampling rates are cleaner now and believe me, it is no placebo effect. You can read about the specs of what this nifty device does on the internet everywhere so I won’t bore you with that. The presentation is great (see pictures) and gives you the premium feeling the moment you get it in your hand (just like other ifi products). The device is smaller than you think or have seen on the internet which is why I posted some snaps from afat for you to decide what size it will be. Us, audio enthusiasts (I hate the term “audiophile”) are cool with honky looking gear, but this has no such look. It’s elegant (even has two small blue lights so you know it’s working) and yes, it does make sonic difference. You will hear almost no jitter or distorted noise you even never knew you had in the past. Once you use this, you won’t go back. I have multiple USB DACs. If the price was not quite steep I would have ordered three of these. So, yeah, it is a bit pricey for what it is but it is worth the money. Better than buying two “jittebugs” from other companies in my opinion and yes I do own other jitterbugs. Recommended!

100% satisfied!
I had annoying high-frequency noise from monitor speakers. I doubted this product, but the noise is gone after I plugged it into my audio interface. Moreover, it produced better sound. It could be a placebo effect, but I hear the wide stereo image and more clear sound. I strongly recommend!

OMG!! This product is amazing. it feels premium and has a little weight to it. I have the Mayflower ARC connected via USB to my PC and PS4. This usb purifier gives an amazing clean sound. The Mayflower ARC have an unbelievable amazing and gorgeous sound, but let me tell you; when it is coupled with this little guy it gives you another whole level of detail in games and music. The Bass is “punchy” the high are high, the mids are mids, you hear the whole package and with a livelyness that has no comparison whatsoever. I bought the IFI SPDIF signal purifier for my home cinema, and that’s another story of awesomeness and amazing sound that I will review it later.

This usb-3 purifier made a Noticable difference in realism ,depth of detail and much more more dimensional.
I spoke with The tech Alex at a Ifi Audio and for breakin , bareminimum of 100 hours. 150 roughly to full breakin,
Also the addition of theirUSB cables make it better still , they also make a micro foraround $400 that if you purchase these they will never leave . I have had ps audio $6k dac in mysystem and the Ifi Audio made it bettersounding Period. I could not be happier
I am saving for their top Usb isolation ,that be8ng said for $130 this is noticable better then the 2 purifier even when new.
A well over 5% improvement acrossthe board .the best value on the audio market IMO !!

What a great product. I have a powered, 12 outlet USB that used to give me problems with dropped signals and interference on the mice /keyboards. I also had poor signal recognition on initial connect of accessories. All of that is fixed beyond what I could hope for.

iFi Audio will not rest until every signal passes cleaner and purer than ever before. This time they’re ensuring a solid signal between a USB audio chain. Meet iFi iPurifier3.

iFi iPurifier3 has been designed with new features that improve upon the usability and performance of the previous versions. This iteration is fit with acclaimed noise-cancelling adapted from military radar defense technology. Touted as the cornerstone of ever-improving iFi USB audio technology, ANC works by creating an inverse sound wave to the surrounding noise, subsequently cancelling it out, and resulting in a muted background up to 40dB. This works for any incoming noise.
