iFi audio ZEN Stream Wireless Network Streamer

Just add Remote Control
Beneath its classy exterior, the ZEN Stream is a technological streamer-de-force. It has one purpose to send music from the Internet to your DAC with no loss of quality. True hi-res performance of PCM384/DSD256 via WiFi/LAN. Just add your smart device as a remote and away you go. Optimised open-source architecture works with multiple dedicated platforms, completely and perfectly future-proofed as it is constantly updated. Ease of use audiophile implementation. It is the bee’s knees of Streamers.

Warp speed tech
ZEN Stream is a true ground-up design. The hardware and software implementation is quite exceptional:

• Two SuperSpeed USB3.0 ports with Active Noise Cancellation II
• S/PDIF out with the iPurifier built-in
• Power supply with Silent Power tech
• iFi software developed with Volumio open-source as the starting point, then coded and optimised by us to achieve the purest streaming software bar none

These are some of the factors behind why the ZEN Stream is at the cutting-edge handling PCM384/DSD256 on LAN and WiFi (802.11n, with 100Mbps on 5Ghz).

‘Exclusive’ for your ears only
The 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.

This ensures that the ZEN Stream is not merely a ‘jack of all trades’, but a master of all too.

Who’s who of Streaming
Hot off the press, the ZEN Stream has the following connectivity options:

• Stream straight from Spotify/Tidal apps with Spotify Connect and Tidal Connect
• Works with any DLNA certified streaming app (our own app is imminent!)
• Integrated Airplay and Chromecast* (Chromecast to be implemented in the near future) – easy streaming from Apple and Android devices
• Roon compatible – basically, it adds Roon to any DAC.
• NAA operation in conjunction with Sygnalists HQPlayer software

Tech savvy
Beneath the unassuming casework sits some serious horsepower in terms of both technologies and components:

• 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
• 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

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.

Our ‘exclusive modes’ give you individual settings dedicated to specific modes of operation to deliver the purest possible performance.

• All-in-one
• DLNA streaming
• NAA streaming
• Roon Bridge streaming
• Tidal streaming

Hi-Res WiFi
Dual-band Wi-Fi reception supports 802.11a/b/g/n/ac for a fast, reliable wireless connection.

SS ANC II
The USB ports  support the SuperSpeed USB3.0 standard and benefit from iFi’s Active Noise Cancelling technology to remove distortion from the audio signal. 

ARM. Powered
The circuit design has been painstakingly engineered to deliver superb sound, with processing muscle supplied by a 64-bit, quad-core ARM Cortex microprocessor.

GMT (Global Master Timing)
Both of the two digital outputs asynchronous USB and coaxial S/PDIF that provide connectivity to an external DAC or an amp with digital inputs are regulated by iFi’s femto-precision GMT circuitry to eradicate jitter from the digital audio signal.

Intelligent Ethernet
The device uses a high-performance Ethernet switch with a low-power integrated 5-Port Giga-PHY.

High-PSRR
We’ve utilised high-PSRR, low idle current, low-dropout voltage regulators with soft start. This means maximised efficiency and minimised system noise.

Synchronous
Add to this, a synchronous 1.5MHz high-speed power supply controller for even great noise reduction and even less distortion.

Taiyo Yuden
Carefully chosen circuit components including discrete, high-grade surface-mounted devices such as TDK C0G multilayer ceramic capacitors and inductors from Taiyo Yuden and Murata add to the quality build of this product.
