Whether you are a movie buff or a hardcore gamer, the SPDIF iPurifier will make sure sound matches vision with stunning quality.
So, you’ve got a TV with crystal clear picture quality? Or an Xbox One X with stunning graphics?
But something is still not quite right. Soundtracks are lack lustre and footsteps remain undefined.
You need the SPDIF iPurifier.
SPDIF is the main digital audio output signal for devices such as Apple TVs, PS4, Xbox and 4K Smart TVs.
It is common in mainstream devices for the SPDIF signal to suffer from low quality transmission and an abundance of jitter.
Got neighbours with noisy power? This can corrupt yours too.
Add our SPDIF iPurifier to get a fully restored, jitter free signal that adds greater dynamic contrast, greater warmth and sharper detail to your sound.
Netflix will never have sounded so good.
The SPDIF is multi-talented. It works with Toslink and digital cables on practically any SPDIF source.
And, as it can output both SPDIF and optical at the same time, you can connect it to two devices at once!
Plus, it can double as a coax SPDIF to optical converter.
It’s Bit Perfect – it doesn’t over or upsample the signal. It’s compatible with DTS, DOLBY Digital and DoP signals and offers full HD support up to 192KHz.
Soundtracks rock and games feel immersive. Cracked it.
Extensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and the intelligent memory buffer.
The low-jitter crystal clock has been updated to provide >20dB better performance
The signal goes through 4 comprehensive stages – isolation, regeneration, a memory buffer and re-clocking. This restores the industry standard ‘square wave’ which represents the desired signal.
The result is a fully-restored SPDIF signal without jitter. The sound quality now has greater warmth, resolution and dynamic contrast.
Extensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and intelligent memory buffer. This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.
A galvanically isolated SPDIF output means that electrical circuits are separated to eliminate stray elements – a signal can pass but nothing else. Interference-free audio.
And with added Reclock® and Regenerate® the signal remains true and strong.
We pride ourselves on giving you Bit-Perfect signal transfer. This means the signal remains original and unchanged.
This device 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.

Watch it here…
Got a new Rotel A-12 integrated amplifier last month and am very happy with it. The only thing I noticed (after all this burn in time) that I didn’t like is that some items with complex tonality, like Karen Carpenter’s voice… pure high tone with that special depth that made her voice so memorable was missing the latter. I was thinking strongly about buying an external DAC, but after reading about this item I thought I try it. GLAD I DID.
Not only do I now her Karen’s voice in ALL it’s glory, I hear ALL the richness in other items like pianos, harmonicas, voices, violins, etc. Basically any item where sound is made by vibrations controlled by air flow passing over chords/reeds of some sort (voices, harmonicas, reed instruments) or manually struck (piano, violins, etc). Note I’m a subtle but NOTICABLE difference. I also agree that it cleans up the background of noise and distortion so it makes it easier to hear items in the background that used to be missed.
Do yourself a favor and try it. You can always return it. But my guess is you’ll keep it.

“It absolutely does what it promises…it actually made my listening tests more enjoyable”
“The iFi iDefender 3.0 and SPDIF iPurifier are two dongle offers from iFi that are out to clean up your source gear; one for USB, one for SPDIF. Both of these actually do their job quite well, and the iDefender is making its way into my personal setup.”
The damn thing works. It works both on SPDIF/coax input using my CD player as a transport into my supposedly magical jitter-irrelevant ASRC enhanced wonder DAC, and on the Toslink output from the TV fed by USB inputs from a Roku, a blu ray player, and a video game console into that same DAC. But it doesn’t do both at the same time.
If you want to use both SPDIF and Toslink sources at the same time without flopping cables around, you’ll need two of these little turds. But it does work. The level and kind of improvement is similar to a power supply upgrade to a preamp or turntable.
I think of myself as a man of science. I try not to believe in anything and to rely on proofs and experiments as much as I can.
If I can’t measure something, I try to understand how it works in theory and therefore how it should behave, and if things I find out are supported by theory or not. Let me say right at the start that I don’t believe in cables making a difference, but that’s because I think there’s nothing to be believed – something either works or it does not, there’s no need to believe.
We’re talking about cables, not some god or the immortal soul. We have this saying in Italy which goes roughly like “I’m like Saint Thomas, I don’t believe in things unless they’re right in front of me” – that’s my approach. So when I was asked if I wanted to try the iFi SPDIF iPurifier, I was interested in finding out whether it worked or not.
If a file is “Bit Perfect’ it means it has stayed the same. For example, if a PCM file is played through a DAC to improve the sound quality and the DAC does not change the file format. The file is ‘Bit Perfect’.
The DoP protocol is a method for transferring DSD Audio over PCM. DoP simply uses PCM frames as a carrier for the native DSD data. A DSD stream can be carried over a lower data stream and will be completely unchanged at the end of the process.
Dolby digital is one of the most popular formats for surround sound. It’s used by DVD’s and Netflix.
It is a compressed format, so the newer uncompressed formats sound better.
DTS is a company that licences codecs. They dominate the physical disc market with DTS5.1 and DTS Master Audio.
Galvanic isolation is a design technique that separates electrical circuits to eliminate stray currents that contain noise. Signals can pass between galvanically isolated circuits, but stray currents, such as differences in ground potential or currents induced by AC power, do not pass. This means little or no noise interference to the audio signal from stray currents.
The square wave pattern is what is desired in audio. It contain more harmonic content than a sine wave or a wave full of distortion and jitter.
