I did this with Yahoo's LaunchCast and thought it sounded pretty bad. Even on the high quality setting the audio wash washy. Could just be LaunchCast as I know they run it through some kind of filtering. This is nothing bad with the 990, LaunchCast sounds like crap on my Klipsch Promedia 2.1 speakers hooked to my desktop as well. It is great for light background music, but nothing I would want to listen seriously to. I need to get my Sirius radio the wife got me for Xmas activated and see if it is any better.
