X-Fi is a technology for improving audio quality from standard sources including MP3 players and streaming sources. They’ve stuffed this technology into a set of wireless devices, the XDock Wireless dock and the X-Fi Wireless Receivers. You plug in an iPod into the XDock and can play music out to an optical or RCA-enabled receiver. Then, you can transmit the audio to a Wireless Receiver in another room. The receivers are $99 and the XDock is about $199 for the iPod. The package will cost about $300.

Seems like a great way to spread music through the house.
