Open-source architecture – audio streaming unleashed
Many audio streaming devices lock users into a specific platform. That is not necessarily a problem, assuming the facilities on offer are in line with the user’s requirements and they are happy with the interface. But, if they want to select their preferred streaming platforms and apps without restriction, with the ability to adapt and evolve as requirements change, a device with an open-source architecture offers clear advantages.
One open-source solution that has been making waves in the audio streaming community is the Raspberry Pi – the well-known single-board computer, which can be used as a music streaming device. After all, an audio streamer is essentially a computer that combines hardware and software to perform a specific task. The Raspberry Pi is effective, inexpensive and not tied to a specific platform, giving the user plenty of streaming options. The flipside, however, is that the Raspberry Pi is complicated to set up and has not been designed and optimised for high-performance audio straight from the box.
The ZEN Stream offers the best of both worlds in one unique package. Its open-source architecture ensures the user is not tied to a specific platform or app, offering a wealth of options and the ability to add more via programmable firmware. Its Linux-based operating system offers exceptional flexibility, with the streaming community encouraged to work with iFi to create additional features to add down the line via OTA (Over The Air) updates.
Coupled to this flexibility is the fact that – unlike the Raspberry Pi – the ZEN Stream has been designed from the ground up for the sole purpose of high-quality audio streaming. The hardware has been built to deliver the best possible sound quality, working in perfect harmony with iFi’s in-house software development. From the device 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.
Superb sound, no matter how you stream
The ZEN Stream’s hi-res audio credentials are top-notch, supporting PCM up to 32-bit/384kHz and DSD up to 11.2MHz (DSD256) over Wi-Fi – highly unusual – as well as over Ethernet cable. There are multiple ways in which the device can interface with your music collection or favourite streaming service, depending on the user’s preference, and thanks to the ZEN Stream’s open-source architecture these will expand over time. Here are some of the options provided at launch:
Integrated Tidal Connect and Spotify Connect
Users of these hugely popular online music services can stream directly from the Tidal and Spotify apps – simple, seamless and effective.
DLNA certification
Any DLNA-compatible streaming app – including iFi’s forthcoming Stream-iFi app – can be used to control the ZEN Stream and access audio content from online services and DLNA-certified network storage devices.
AirPlay and Chromecast
Integrated Airplay and Chromecast ensures easy streaming from Apple and Android devices. AirPlay is included at launch; Chromecast will be added as a free firmware update later this year.
Roon compatibility
The Roon platform has become the standard-bearer for high-quality digital music management and streaming – a great interface, strong flexibility and high-quality sound are all benefits, although Roon-compatible hardware does not tend to come cheap. At launch, the ZEN Stream is compatible with Roon Bridge software, making in suitable for a Roon environment, and full Roon Ready certification is in the pipeline – a tempting proposition given the ZEN Stream’s affordable price point. With the ZEN Stream, you can add Roon compatibility to any DAC on the planet.
NAA operation
The ZEN Stream can operate as an NAA (Network Audio Adapter) in conjunction with Sygnalist HQPlayer software – favoured by many serious music streaming enthusiasts. This means it can direct packets of audio data received over Wi-Fi or Ethernet cable straight to the connected DAC without applying any processing whatsoever.
iFi delivers hot exclusives
An ingenious part of the ZEN Stream’s design is the ability to select between ‘exclusive modes’ – individual settings that deliver fully optimised performance by focusing operation on one particular mode of use. The following modes are provided:
All-in-one - This non-specific mode is great for all platforms, audio formats and devices.
DLNA streaming - Select this mode to optimise performance when using the ZEN Stream with DLNA-compatible apps and devices.
NAA streaming - Select this mode when using the ZEN Stream as a Network Audio Adapter in conjunction with Signalyst HQPlayer software.
Roon Bridge streaming - Select this mode when integrating the ZEN Stream into a ROON environment.
Tidal streaming - If you’re a subscriber to Tidal’s Masters Tier and use it exclusively, this is the mode for you.
