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.
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.
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.
At an entry level audiophile price, the SPDIF iPurifier produces next level results that’ll leave you speechless.
The SPDIF iPurifier includes:
Accompanying the SPDIF iPurifier is our very own iPower 5v plug, which being super-quiet, lowers the noisefloor to the max.
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.

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…
Product is easy to use and seems to be purifying my coax signal as exactly as described.
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.
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.
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.
