I will say that XM is a lot better via DirecTV than through a satellite radio either car or home style. I had the free trial in my Honda and music was bad and talk, done at an even lower sampling rate, was worse. I would have liked to have the variety but the sound is awful using a Sat radio. If the quality was as good as DirecTV I would still have it in the car. I emailed them asking about sampling rates they use for both and they said they could not release that info.....
