A basic Sonos 150 bundle (£749) contains all the equipment you need to get started including a ZP120 Zone player, which comes with a built-in amplifier and all the other control and access gubbins; a separate wireless colour touchscreen remote; and a ZP90 Zone Player - a basic Wi-Fi box that enables you to stream your music to a hi-fi in another room.
