Have a look at these: bluesound, audiopro, bang-olufsen, denon. Depending on which software is in use for streaming operations, you could also use ‘standard’ WiFi-enabled speakers like something from KEF (LS50) or dynaudio. Just from top of my head. Maybe someone else has a comprehensive liste at hand.
