Streaming XM from a player compared to Pandora One, there is no comparison. Like comparing AM radio to CD. I can play the Pandora at lower volume and it has much better stereo separation. I have to tinker with the artist I pick for the station. Put in Johnny Cash and was hit with an onslaught of Waylon Jennings, Roy Orbinson, etc. Not that I mind them, but they sometimes play similar artist like these in a row. Someone coming in will think they are in a Quentin Tarantino movie.
