The iPurifier2 is designed to be bit perfect – to not over-sample or up-sample the signal. It's compatible with DTS, Dolby Digital, and DoP signals and supports signals up to 192 kHz. It works with optical and digital coaxial connections from nearly any S/PDIF source, and can output to both optical and digital coaxial at the same time, allowing for simultaneous connection to two audio systems. It can also function as a digital coaxial to optical converter.

The signal goes through four stages: isolation, regeneration, a memory buffer, and re-clocking. This is designed to restore the square wave, which represents the desired signal, restoring the S/PDIF signal without jitter with more warmth, resolution, and dynamic contrast.

AMR's Global Master Timing (GMT) / Memory Buffer System is engineered to solve the S/PDIF digital signal jitter problem. Reclock and Regenerate are designed to add further strength and fidelity to the signal.

The galvanically isolated S/PDIF output separates the electrical circuits to help eliminate stray elements, so only the signal can pass through for virtually interference-free audio.

Designed to reduce jitter for enhanced dynamic contrast, warmth, and detail
10 MHz Global Master Timing femto clock
Four tantalum 100μF capacitors to augment the power supply ripple
MCU firmware for performance optimization
Galvanic isolation, gold-plated EMI/RFI shielding, and the included iPower power supply help boost performance

Related Questions and Answers

Q: 1. Does this include a 5 volt power source as recommended in the manual?

A: No, the iFi audio ZEN Air Blue Bluetooth Audio Receiver would not include a 5 volt power source.

Q: 2. Can I still use the volume control on my keyboard? I read reviews of an older ifi DAC that said you couldn't with that model.

A: Regarding the iFi Studio ZEN One Studio Universal DAC Audio Interface, having the ability to use your keyboard's volume controls would depend on the software application you are using at the time.

Q: 3. The picture for type A looks like type C, is the picture wrong?

A: It is Type C male to Type A female.

Q: 4. Will this work with a 2019 Apple Mac Pro USB C outlet?

A: Yes, this would be compatible with 2019 Mac Pro.

Q: 5. Will it work plugged into router and improve wifi signal,specifically buffering and sound quality?

A: The iFi audio LAN iSilencer BH #IF0306056 will not work to boost Wi-Fi single. The LAN iSilencer is engineered to filter out noise and prevent interference from affecting the digital audio stream.

Q: 6. Is the output from the balanced output on the back muted when you plug in balanced headphones on the front?

A: The iFi audio ZEN CAN Signature Premium Desk-Fi Headphone Amplifier (BH # IF0311016) offers two active balanced outputs. Both remain active regardless of which one is connected.

Q: 7. is the Zen Stream power adaptor 9v or 12v?

A: According to page 01 in the manual for the iFi Zen Stream, the power adapter is DC 9V. https://www.bhphotovideo.com/lit_files/723691.pdf

Q: 8. Your overview text/bullets indicate optical as an output option while image of ports says optical input. Which is correct?

A: The iFi audio ZEN One Signature All-Purpose Digital Audio Hub BH #IFZENONES has a TOSLINK Optical S/PDIF Input.

Q: 9. Can we use the iFi audio ZEN CAN Signature Premium Desk-Fi Headphone Amplifier as a Preamp connected to a separate power Amp?

A: The iFi audio ZEN CAN Signature Premium Desk-Fi Headphone Amplifier is not intended to be used with anything other than a pair of headphones. The impedance of the current it puts out can reach the 600 ohms maximum of standard line output, but there would really be no purpose in connecting it to a speaker power amplifier and results are likely to vary based on the specifics of the use case. You also risk "loading down" a line level input if the output impedance is not set correctly, which will degrade signal quality.

Q: 10. Will this device eliminate audio ground noise from HDMI audio?

A: The iFi audio HDMI iSilencer HDMI Noise Filter with Surge Protection (BH #IFHDMIIS) is designed to reduce video noise and jitter from the HDMI signal. It does not provide a solution for AC ground noise.

[8 x 3.5 x 1.9"] Great sound from a tiny package. USB powered, no wall wart or power cable needed. Head phones and powered speakers work fine with it. Perfect for videos and music from PC. 5

[0.895 lb] I bought this with the expectation that it likely would not do anything, and I'd return it. When I inserted it between my Sonos Port and a Denefrips Ares 2 DAC, however, I noticed an stark increase in dynamic range, to the extent that I had to turn my headphone amp down a bit. Through speakers, I noticed better imaging and placement, as well as better base. I checked in with the DAC manufacturer to see if this could just be the result of the iFi potentially feeding a hotter signal than the Port. They said that was unlikely, and reducing jitter would indeed be helpful to improve the DAC's sound. Of course, Denefrips solution for that costs many times the iFi. I'm keeping it, which surprised me. I expected only marginal improvements. The Sonos Connect was known to produce a lot of jitter. I had assumed the Port would improve on that, but perhaps not if I'm hearing such a jump from the iPurifier 2. I'm sure this is all system dependent, but my experience is that it is worth trying, if you buy from a vendor with good return policies. 5

[8 x 3.5 x 1.9"] As soon as you open the box this product is impressive for its build quality, simplicity, and ease of set up. Just download the app and complete a few easy steps and your streaming. 5

[0.895 lb] No issues so far� Music sounds a little better 5

[1.98 oz / 56 g] My audio gear: two Devialet Phantoms, Bluesound Node (3rd Gen. ), tested with Tidal. A/B comparison plugging/unplugging the iFI iPurifier: clearer, more "airy" sound, better dynamics, more controlled bass, larger soundstage. I still am surprised it works as promised, I returned other, more expensive/bulkier AC purifiers because they killed the dynamics, producing a flat, uninterested sound. Great addition! 5

Thomas	25/06/2024
[1.98 oz / 56 g] This device is well worth the cost! I noticed immediately, a lower noise floor, better separation of instruments, deeper, wider soundstage. Highs are clean, without glare. Mids are clean and rich. Lows have more grip and well defined. Well done iFi! 5

Richard	17/06/2024
[1.98 oz / 56 g] Works as advertised. To verify your hum will be eliminated, use a three prong to two prong adapter (cheater plug) to TEMPORARILY remove the ground connection. If multiple devices are involved each one may need a cheater plug to eliminate the hum. If the hum is gone, replace each cheater plug with a IFi Audio GND Defender and enjoy. 5

Alex	07/06/2024
[1.98 oz / 56 g] I wanted a device to transmit audio to my analog amp from phone in bed room. I was debating between this air or the regular version. At the end I picked this air version because the two are exactly the same other than the digital output and metal finishing. The sound is very neutral, a bit on the warm side to my ear and love the flexibility to connect different codec. I'm very happy with purchase. The only thing I wish be better is the power cable is only two feet long. I have to place it behind my speaker to reach the outlet. 5

[0.895 lb] I needed to add a separate streaming Roon end point for headphone use via a DAC. I looked at what was available to stream with a noise free and good time output to a DAC. iFi ticked all the boxes at a very low price point when compared to other options. The Zen has SPDIF and USB for the digital DAC outputs. I used the USB. Both Outputs have tech to insure that noise/timing issues has been limited to a minimum which is very important ( Rubbish in means rubbish out). Ethernet used since this ensures no dropouts or throughput issues. You will have to set the system mode selector (Roon for me) so again one should know what you are using or plan to. It was straight forward to set up by going to ifi websight (internet search if in doubt). Performance wise this sends a very good digital stream to my DAC. No issues with timing or noise. The imaging and musical enjoyment match my Roon driven /SSD NAS / Meridian MS600 endpoint. So full thumbs up for very little money. 5
