The Creative Xfi Dock, powered by the Creative X-Fi audio processor, makes your MP3s sound better, according to reviews. It does so by restoring the audio information that was stripped during conversion to the MP3 format. The Z600 model includes two speakers and an 8-inch subwoofer. It also has auxiliary inputs, so you can plug your iPod into it.http://gizmodo.com/216121/creative-x+fi-z600-dock http://www.ilounge.com/index.php/reviews/entry/creative-xdock-x-fi-dock-for-ipod-with-wireless-streaming-and-x-fi-wireless/

The dock has a 2.4 Ghz wireless transmitter, an infrared remote control, S-Video and composite video out ports for 4G and 5G iPod users, an optical and audio output that auto switches, a USB port, a headphone port, and a line-in port. It comes with optical audio and S-Video cables.http://www.ilounge.com/index.php/reviews/entry/creative-xdock-x-fi-dock-for-ipod-with-wireless-streaming-and-x-fi-wireless/

Reviewers say the Creative Xfi Dock improves the sound of MP3 recordings, but it downgrades the quality of digitally remastered recordings.http://www.ilounge.com/index.php/reviews/entry/creative-xdock-x-fi-dock-for-ipod-with-wireless-streaming-and-x-fi-wireless/ http://gizmodo.com/216121/creative-x+fi-z600-dock

Xfi is an abbreviation for Extreme Fidelity.http://www.creative.com/soundblaster/technology/welcome.aspx Fidelity in sound traditionally means the quality of sound. The last major breakthrough from simple recorded sound to high fidelity sound was brought about by the motion picture industry (movies) in the 1930s. Key inventions from this prior advance in technology were: FM transmitters, stereo sound, and electroacoustic analysis. At the time, all this was done with vacuum tube electronics.http://www.nutshellhifi.com/library/tinyhistory1.html
