Afaik there are no cd quality streams. But listening through my 25.00 Sennhisers plugged into the headohone jack at my computer at work, it sounds pretty good. I've never listened at home on my stereo.
You should also try: Imeem, accu radio, lala, jango, myradio live!, nugs.net {if you like jam bands like i do} radio io, and even aol radio. Lots of choices!
