Denon debuted a line of Sonos-like wireless multi-room HiFi speakers that stream audio from both Internet and local sources, and run on embedded Linux. Like the similarly Linux-powered devices available from Sonos, Denon’s “Heos” wireless streaming speakers offer multi-room (multi-speaker) synchronized audio, and can deliver multiple audio streams from disparate sources to individual speakers or stereo-configured speaker pairs distributed around the home.
