We've long been fans of the Sonos Digital Music System, which lets you stream all manner of digital audio throughout your home. The latest BU250 bundle is an enthusiastic CNET Editors' Choice, in part because it can be controlled either via the included touch-screen controller or with any iPhone or iPod Touch (running a free Sonos Controller app). Unfortunately, it costs $1,000--not bad for a two-room system, but still out of reach for many consumers--and it needs to be connected to external speakers or audio components to hear the music.
The new Sonos ZonePlayer S5 aims to address both of those issues. It boasts an all-in-one design with built-in stereo speakers, so it's plug and play. And it costs $400--not cheap, but well within the price range of refined iPod speaker systems we've seen from Bose, B&W, and other luxury brands.
