Media streamers were a dime a dozen at this year’s show, so only a truly envelope-pushing home entertainment system would rise above the others to take the crown as best in class: the Logitech Squeezebox Duet Network Media Player.

Simply hook up the receiver to a stereo system or home entertainment center and you can stream music from your Mac or PC via Wi-Fi. Multiple Squeezebox Duet systems allow multimedia mavens to sync the receivers together to broadcast a song throughout the home, or more remarkably, listen to different songs in each room. Courtesy of Logitech’s SqueezeNetwork, the $399 Squeezebox Duet features always-on Internet radio and aggregation (from sources such as MP3Tunes, Pandora, and Rhapsody) that lets you stream music even when your notebook is off.
