I recently decided to give the Squeezebox Server on my MediaSmart EX495. If you are not familiar with any of the Squeezebox products, they are worth looking at if you'd like to have a device that can connect to your stereo and your network, and play your audio files from a centralized file repository. Squeeze products were originally developed and marketed by a company named Slim Devices, however Slim Devices was purchased by Logitech in 2006.
A few years ago, I got an early release unit of a Squeezebox Duet, which essentially Logitech's answer to the high-end (and high-priced) SONOS music system. Admittedly, it is not as flashy, but it does the trick. It comes in two pieces: a small box that plugs into an amplifier as well as your network, and a handheld remote with a color screen, and WiFi connectivity, so that you can control the Squeezebox.
