This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life…
Got 4K TV, Xbox or PS4? Turbocharge the optical.
Apple and 4K Smart TVs. Google Chromecast. PS4s and Xboxes – they’re amazing.
But they all have the same flaw: Sound that degrades and affects your gaming and viewing pleasure.
The cause?: SPDIF digital audio output and unclean power supply.
The SPDIF iPurifier cleans both and puts your audio back in the game.
The Noisy Neighbours
And it’s not just your devices that degrade the sound, unclean power from your neighbour’s power supply corrupts yours too, leaving you with audio that seriously under-performs.
Silence Is Golden
The SPDIF iPurifier plugs into your SPDIF port and solves audio issues instantly. It makes the square wave ‘square’ once again.
Vocals and instruments on songs are separated, TV and movie audio becomes bigger and gaming becomes clearer.
Sound just becomes much more realistic.
This Is The Life
At an entry level audiophile price, the SPDIF iPurifier produces next level results that’ll leave you speechless.
The SPDIF iPurifer, give your audio system a new lease of life.
The Tech Spec
The SPDIF iPurifier includes:
- REclock/REgenerate technology To ensure you hear audio in its natural form, and
- Galvanic Isolation To stop noise contaminating the signal
Accompanying the SPDIF iPurifier is our very own iPower 5v plug, which being super-quiet, lowers the noisefloor to the max.
Audio never sounded so clean.
Run your signal through this device to get the industry standard square wave and get rid of jitter.
The signal goes 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.
AMR/iFi prides itself on assuring Bit-Perfect signal transfer. This means the signal remains original and unchanged. This device ensures a Bit-Perfect transfer which is highly unusual for S/PDIF 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.
A galvanically isolated S/PDIF 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® our fastidious attention to sound quality never waivers.
AMR’s Global Master Timing (GMT)/ Memory Buffer System represents a total ‘out of the box’ systematic digital solution that solves the digital S/PDIF jitter 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.

Overview of iFi Audio accessories and filters – does filtering matter?
iFi iPurifier Works
Product is easy to use and seems to be purifying my coax signal as exactly as described.
Found while reading Darko audio.
Nice product with multiple connection options. Well packaged. I’m using this with my chromecast audio for streaming. I first saw this while checking out Darko audio reviews.
I had a persistent ground loop issue on a high end surround sound system.
I was skeptical this would fix it but it did so instantly with no further issues.
NEVER HEARD background coughing before this filter!!
I know that there are a couple of scientific reviews which say that this filter injects noise into the circuit. To that I say BAH!!
I wanted whole house sound when streaming TIDAL, so I ordered several Chromecast Audio dongles a few weeks before Google decided to discontinue them.
Then I read about upgrading Chromecast Audio with Ethernet input (vs. WiFi), a linear power supply (also from iFi) and this anti-jitter filter. POW!! The difference in HiFi sound from TIDAL was detected by my spouse who generally does not notice subtle audio differences. Blur, pre-ring, and noise were limited to the extent that on Diana Krall’s “A Case Of You” (from Live in Paris Album) at 16, 32, and 41 seconds, for the first time I could hear background noise. Raised the volume until I could hear it was people coughing in the audience!! Listened to this cut many times and NEVER HEARD background coughing before.
Upgrade your CCA
I wanted a good stepping stone solution to my upgrade path. I have a Chromecast Audio ((which increased my enthusiasm for listening to music on streaming services (Tidal, Spotify)) and wanted a step up in quality before going on to a superior solution; such as a Raspberry Pi with ALLO DigiOne Signature.
This little device transforms the quality of the CCA, creating a sound with a much fuller, taller, broader and meatier structure, which will possibly benefit from pulling the speakers away from the wall a little more for balance.
As a bonus I have a decent (included) power supply for use with the Allo/RPI combination later on!!!
I’m very pleased with the results.
