In case you weren’t familiar with the ZonePlayer/CONNECT, they are accessories which you connect to your regular home theater or stereo setup, which you can then use to “stream all the music on earth” to the audio equipment you already own. All the music on earth basically means music from iTunes, Pandora, Napster, other internet radio stations and more.
All the connected speakers and devices can be controlled from one central iOS device (iPhone, iPad, iPod touch) that’s connected to the same WiFi router, via an app. With tons of options and customizability, Sonos’ CONNECT and CONNECT:AMP (which has an integrated 55W/channel amplifier to power your speakers) is great for folks who have loads of speakers all over the house and are looking for a way to control all of them from one device.
