Released July 2021, ZEN Stream by iFi Audio is a technological streamer-de-force. It has one purpose – to send music from the Internet to your DAC with no loss of quality. Ease of use + audiophile implementation. ZEN Stream is the bee’s knees of streamers.

Get true hi-res performance of PCM384/DSD256 via your WiFi / LAN connection. Just add your smart device as a remote and away you go. ZEN Stream offers optimised open-source architecture, it works with multiple dedicated platforms, is completely and perfectly future-proofed as it is constantly updated.

ZEN Stream has one of the most fully-optimised software platforms in the world. From the device’s drivers, to the kernel (the heart of the operating system), to the shell (which interfaces with the kernel), to the applications and the user interface — everything is fully optimised for seamless operation and excellent sonic performance.

An ingenious part of the ZEN Stream’s design is the ability to select between ‘Exclusive’ modes – individual settings dedicated to specific modes of operation to deliver the purest possible performance. All other programs are shut down – to minimise ‘software jitter’ — an often overlooked aspect that negatively impacts the quality of computer audio playback.

Beneath the unassuming casework sits some serious horsepower in terms of both technologies and components, including a powerful 64-bit quad-core ARM Cortex microprocessor, USB and S/PDIF interfaces regulated by femto-precision GMT clock to eradicate jitter, Active Noise Cancellation II and iPurifier technologies for USB and S/PDIF interfaces respectively. An Intelligent Ethernet switch controller, high-PSRR, low idle current, low-dropout voltage regulators with soft start, synchronous 1.6MHz high-speed precision power supply controller, C0G capacitors and Taiyo Yuden and Murata low ESR inductors too.

This is a true hi-res device. It uniquely supports PCM up to 32-bit/384kHz over Wi-Fi as well as Ethernet cable, plus DSD up to 11.2MHz (DSD256). Highly unusual in a Wi-Fi streamer.
