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.
