1. The Controller: Logitech Squeezebox Radio
The Squeezebox acts as an Internet radio and a wireless bridge between your home network and the Web. The controller lets you pick songs, albums, artists, genres, and playlists and zap them to your speakers.
2. The Speakers: Libratone Live
This 360-degree speaker cabinet contains five amplifiers that spread sound in different directions to immerse a room in an acoustic bubble. It's got AirPlay technology, which means it can stream music from any iTunes device.
From $699; libratone.com
3. The Player: Sonos Play:3
The Play:3 connects multiple "players" (each includes speakers, amps, and a receiver) that you control with a free Sonos app, and it can also stream music (Spotify, Rdio, Pandora) to all the players at once.
$300 per player; sonos.com
4. The Home Theater: Aperion Intimus 4T Summit Wireless 5.1 System
This easily installed system's uncompressed 24-bit streaming sounds as good as a wired setup. The controller calibrates itself, so you can simply plug it in and prepare to be blown away.
