iFi ZEN Stream

iFi ZEN Stream — pure audio streaming

For users looking for audiophile quality without compromise, the iFi ZEN Stream delivers the purest digital audio transmission. This network audio transport does not contain a DAC and is designed for bit perfect streaming without any DSP or conversion. With support for Hi-Res formats up to PCM 384 kHz, DSD256 and MQA, it is suitable for the most demanding listeners. The combination of Wi-Fi and Ethernet connections and USB and S/PDIF outputs allows for easy integration into a variety of audio systems.

Pure digital audio transmission

The iFi ZEN Stream minimizes noise, jitter and software interference, ensuring maximum signal accuracy. With "Exclusive modes" optimized for specific streaming platforms, it can turn off unnecessary processes and reduce interference. This approach makes it the ideal bridge between the network and an external DAC, whether it is a device such as the iFi ZEN DAC V2, ZEN One Signature, or other USB/S/PDIF DACs.

Broad Support for Streaming Services and Protocols

Support for platforms such as Roon Bridge (Roon Ready), TIDAL Connect, DLNA/UPnP and NAA (Network Audio Adapter) for HQPlayer guarantees flexibility for different user needs. In addition, a special "All in One" mode provides universal compatibility. This makes ZEN Stream a great choice for various streaming ecosystems.

Connectivity and audio outputs

Network connectivity includes Wi-Fi with internal antenna and a stable Ethernet (LAN) connection. For audio transmission, there are two USB-A outputs compatible with USB 2.0 and 3.0 and a coaxial S/PDIF output with built-in iPurifier technology. This flexibility allows connection to a wide range of external DACs. In addition, it supports playback from USB storage devices, which will be appreciated by users with extensive personal libraries.

Key iFi Technologies

Integrated technologies such as Active Noise Cancellation (ANC) on the USB outputs and iPurifier on the S/PDIF output ensure signal purity at the hardware level. A minimalist design focused solely on audio streaming, along with the option of OTA firmware updates, adds to practicality and long-term usability.
