Enhance the Sound of Any SPDIF Source With iFi SPDIF iPurifier. Drastically Reduce Jitter, while simultaneously output SPDIF and optical instantly to improve the sound of high-end CD players, soundcards, Apple TV, Netflix, YouTube, Xbox, PlayStation, Roku, Google Chromecast, 4K Smart TVs, and more with the ingenious iFi SPDIF iPurifier Conditioner . The aforementioned media platforms all use SPDIF as the main digital audio output. In almost all circumstances, this critical audio signal suffers from low-quality transmission and an abundance of jitter. SPDIF iPurifier changes that by running the SPDIF signal through four comprehensive stages (isolate, regenerate, memory buffer, re-clock) to achieve a fully restored, jitter-free result. You'll hear greater dynamic contrast, enhanced resolution, greater warmth, and sharper detail. Better still, SPDIF iPurifier works with audio sent via Toslink and digital cables - and on practically any SPDIF source, including DACs. And yes, it can output both SPDIF and optical at the same time, which means you can connect to it two devices at once! Moreover, this magical genie doubles as a coax SPDIF-to-optical converter. It ensures a bit perfect transfer, which means the signal remains original (no over/upsampling), so it is compatible with DTS Dolby Digital and DoP signals, as well as offering full HD support up to 24-bit / 192KHz. And since coax and Toslink lack native power delivery, SPDIF iPurifier comes with iFi's 5V DC iPower supply to provide dead-quiet operation. Speaking of no noise: SPDIF iPurifier reduces 50,000 pico-second jitter on most SPDIF sources to five. iFi has indeed thought of everything with the all-aluminum SPDIF iPurifier . Add one anywhere you have SPDIF audio output, clean up that chain or line, and enjoy significantly better sound from your popular devices and streaming platforms.
