The SPDIF iPurifier is partly a nod to past SPDIF devices including the Genesis Digital Lense. With the very latest AMR/iFI technology, it is suited to the gamut of SPDIF sources that are on the market today. It takes any barely recognisable ‘square wave’ and with REclock˚/REgenerate˚ the signal is back to a real-world, perfect wave form.
iFi Audio SPDIF iPurifier
The SPDIF iPurifier is partly a nod to past SPDIF devices including the Genesis Digital Lense. With the very latest AMR/iFI technology, it is suited to the gamut of SPDIF sources that are on the market today. It takes any barely recognisable ‘square wave’ and with REclock˚/REgenerate˚ the signal is back to a real-world, perfect wave form.
From Apple TV to Google Chromecast to PS4/Xbox to 4K Smart TVs, SPDIF is the main digital audio output. As with all mainstream products, the critical SPDIF signal transmitted is of fairly low quality. The SPDIF iPurifier runs the SPDIF signal through 4 comprehensive stages, and the result is a fully-restored, perfect SPDIF with jitter eliminated. The result is sound quality that has greater warmth, resolution and dynamic contrast.
Restoring the Waveform and eliminates all jitter
The signal from SPDIF devices is a digital signal. The industry standard for looking at the quality of a digital signal is to look at the ‘square wave’ (on an oscilloscope).
But the wave is anything but ‘square’, resembling more of a jagged wave. By running through the four major stages of the SPDIF iPurifier the Waveform is back to ideal.
Bit-Perfect audio on all fronts
AMR/iFi prides itself in assuring Bit-Perfect signal transfer. This means the signal remains original and unchanged. The SPDIF iPurifier ensures a Bit-Perfect transfer which is highly unusual for SPDIF devices. It can handle 44.1 / 48 / 88.2 / 96 / 176.4 / 192kHz; 16 to 24 Bit, DSD/DoP, and even Dolby Digital and DTS.
The SPDIF iPurifier has co-axial/optical input AND co-axial/optical output. It works with just about any and every SPDIF product from mass market Apple TV to an audiophile transport > DAC.
Galvanic isolation
The SPDIF iPurifier has no peer. One of the key aspects is that it has galvanic isolation which uncommon. It was however found in the original Digital Lense which retailed at US$1,800 in 1996.
Galvanic isolation is converting a signal from one form to another which will discard spurious noise. This is a major factor behind the SPDIF iPurifier’s ability to stop noise contaminating the signal.
Global Master Timing® + Memory Buffer
AMR’s Global Master Timing (GMT)/ Memory Buffer System represents a total ‘out of the box’ systematic digital solution that solves the digital SPDIF jitter issue once and for all. The Intelligent Memory System holds a large number of complete audio samples, so it may completely absorb a large amount of variation (jitter and drift) in the incoming signal, while still sending out data at a fixed and precise clock rate, regardless of variations in the incoming clock.
Central to the GMT clock system is an ultra-low jitter, quartz-driven clock system (<300 femto second crystal) capable of producing millions of different frequencies with a precision of better than 0.001Hz. Hence, if the frequency shifts from 192,000.002Hz to 192,000.003Hz over a period of minutes (drift) which is the minimum to be meaningful, the GMT clock will intelligently and precisely track the change. This is a core technology of the SPDIF iPurifier.
iPower ‘quieter than battery’ technology
As the SPDIF iPurifier is powered by 5V, it is essential that it is fed by silent power supply. Hence each and every SPDIF iPurifier is shipped with its own iPower (5V). With a noise floor that of 1uV, the iPower is a breed of near silent DC-power supply. Low power consumption and low-noise.
Packed to the brim
With a Bill of Materials (BOM) that stands at 53 individual components, be assured that beneath its unassuming exterior, there are two separate PCBs, each mil-spec’d and packed to the brim with advanced technology.

It works but as day & night as I hoped.

I can confirm the SPDIF iPurifier does work but didn’t offer a scale of improvement I had hoped for with the equipment I paired it with so far.
The first test was a Linn Majik DS streamer. I thought this would be a tough test, and sure enough, it was. The Linn’s sound stage expended a little but nothing to shout about. I knew it to be good, and I had a cheaper kit that I planned to use if the Linn was a bust. Just for fun, I hooked up a Goodman's Module streamer. This was Goodman’s failed attempt at entering the music streaming market some years ago. I understand the original price was around £125, but I picked one up for £14. I have to use the module a lot in the few years I owned it and have been very impressed, but it’s no Linn. Anyway, I reckon if anything is going to output some jitter, the Goodman’s will.
Hooking the iPurifier up to the Modules Toslink socket did confirm what I expected. Everything tightened up, and the sound stage expanded. I have to wonder what a 5v iPower X would add. The iPurifier is going back to the Linn because any improvement is worth having for the price. Incidentally, I was able to A/B test the iPurifier outputs and can confirm it to be a good media converter. That alone justifies the price.

You got a crappy source in a fantastic system which has a decent outboard DAC..... eyes closed this thing is the way to go.

You got a low end source in a fantastic system which has a decent outboard DAC..... eyes closed this thing is the way to go... the results can be breath taking, even on the lesser 44.1/48KHz.
Made no difference what so ever

Bought this to use between the spdif output of my Musical Fidelity Encore and the input to my Musical Fidelity stand alone DAC. Already had a great sound and hoped this would improve it further but unfortunately it made absolutely no improvement what so ever.
