The iFi audio ZEN Stream 3 is a network audio transport. It streams digital audio over Wi-Fi or Ethernet to an external DAC or to an integrated amplifier with built-in digital inputs. It has no built-in DAC and no RCA analog outputs, and it has no analog circuitry.
It uses an open-source streaming engine and a physical hardware selector for exclusive modes. Each mode shuts down background streaming protocols except the one selected, such as Roon mode, which reduces CPU workload. Global Master Timing crystal clocks are used for the USB and S/PDIF outputs. Active Noise Cancellation II and iPurifier technology clean the power inputs and re-balance the digital signals.
It supports Roon Ready, TIDAL Connect, Spotify Connect, Apple AirPlay 2, DLNA/UPnP, HQPlayer (NAA) and internet radio. It handles PCM up to 384kHz, DSD256 and MQA passthrough. A USB drive with audio files can be attached to a USB port for local playback through the streaming app or DLNA.
