Wi-Fi audio transport
ZEN Stream is a true ground-up design by iFi — 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
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).
