There's a lot to love about the higher-end Sonos Multiroom Music System, except its $1,000 opening price tag. But the ZonePlayer S5 aims to make Sonos-delivered music easier on your wallet. The S5 sounds great, thanks to its five built-in speakers—a 3.5-inch woofer, two 3-in. midrange drivers, and two tweeters, each driven by its own Class-D digital amplifier. You stream your music library to it via an iPhone or iPod Touch, desktop software, or add-on Sonos Controller. The S5 also accepts streams from Internet radio and content from such services as Pandora, Last.fm, Napster, Rhapsody, and Sirius (SIRI).
