Oh yeah - the Squeezebox is extremely cool.

I spent months researching and preparing to move to digital audio, and I ripped all of my CDs to flac files over the winter "break". I have been using the Squeezebox hooked to my regular amps and speakers for months now; the sound quality is excellent, and to my ear (and after many hours of comparative listening), indistinguishable from the original CD.

I found that the quality digital/audio converter (DAC) in the computer sound card had a much, much bigger effect on overall quality than the the wireless bandwidth. The DAC on my PC's sound card was horrible, even after I upgraded, but the Squeezebox DAC is very, very good for the price.

SK - the Squeezebox in and of itself might be overkill (and too $$$) for your immediate purposes, but it is a really cool way to expand your access to music without giving up any existing investment in analog stereo equipment. Even if you don't want to use it to play mp3s or other format digital music from a hard drive anytime soon , it has a great web interface and remote for playing music from radio stations on the net or through subscription music services like Rhapsody and Pandora.

[if you think you might be interested in going this route, let me know, because I might have an extra one to sell very slightly used...]
