This is far from audiophile stuff, but I'm using the analog out from my laptop to a cMoy to my K420s to listen to radio online. (I know the cMoy really isn't needed, but it just sounds *better* with it in the chain, I think.)
The sound: reasonable. The music: fun. I started with last f.m., which isn't really radio but is in the neighborhood. The Duke Ellington channel had a lot of music on it that I know like the back of my hand and it was easy to listen to - what I heard was better quality, in general, than the satellite in my car.
Now I'm on a favorite of mine, a.m. 1690 out of Atlanta. The K420s are just right for this kind of listening; they're very forgiving, gloss over the limits of the audio, but also aren't pushy. Nice.
