Our take on the Sony NAS-SV20i

by Ralph Graves

Here's an iPod/iPhone speaker system with a difference. The NAS-SV20i's built-in Wi-Fi capabilities help you enjoy digital music in multiple rooms of your home. Plus, this speaker system can play music you stream wirelessly from your home computer, laptop, portable player or even the Internet.

Great sound from your iPod or iPhone
The NAS-SV20i features two 2-1/2" full-range stereo speakers powered by a digital amplifier. The amp's advanced circuitry ensures you'll enjoy clear channel separation, with amazingly accurate and balanced sound. And if your music needs a little extra oomph, just press the treble and bass boost button.

Stream music from your devices or the Internet
You can stream music stored on your computer to the NAS-S20i to play it through your A/V system. And you can use your computer or docked iPhone to access Internet services such as PANDORA® Internet radio, Slacker, and Rhapsody and stream those tunes through the system. The NACSS20i can also access thousands of Internet radio stations wirelessly, so you'll never run out of listening choices.

The system can also send music wirelessly to compatible devices in other rooms. The NACSS20i is DLNA (Digital Living Network Alliance) compliant. That means it can communicate with any other DLNA devices, such as PCs, media servers, and more, throughout your home.

The Party starts here
This handy system features a Party Streaming option. In Party mode, the NAS-S20i can stream music to compatible HomeShare audio systems such the SA-NS400 network speaker or the NAC-SV10i dock in other rooms. It's whole-house audio the easy way.
