Sony ALT-SA31iR

Sony has taken the wraps off of a new line of streaming audio products, dubbed "Altus." The four debut products will be available exclusively through Best Buy, and the retailer also had a hand in their development. All of the products use Sony's proprietary S-Air wireless technology to communicate with one another, which means that other S-Air-compatible products--including many of Sony's recent home theater and home audio systems--can stream audio to the Altus products.

Sony ALT-SA31iR ($700): This multi-room system includes three components: an iPod/iPhone dock plus two wireless speakers (for listening to the iPod audio in separate rooms). Each component also has a separate built-in FM radio. While the ALT-SA31 looks to be a refresh of the Sony AIR-SA20PK with a slicker design, the new model also includes a remote control with an LCD that offers the iPod's playback info (song, artist, album, etc.), so you're not navigating blindly from another room.
