Sonos BU150

These innocuous-looking boxes hide a revolution inside. Like Sony's Giga Juke series, they form the basis of a wireless multi-room music system. The one at the bottom contains a 2 x 55W amp, the one on top doesn't. Both can output separate streams of audio connecting to a wireless system of up to 32 'zones' - so you can listen to your music wherever you are in your Georgian mansion. On top, you'll see the wireless, iPod-like remote control (you can have up to 32 of these too), and there's software allowing you to control the system from a computer if you prefer. It's a breeze to set up, sounds superb and even supports Napster. Factor in a network hard drive to store your music on, and it's just the wrong side of cheap. But this is one real bundle of joy.
