I have had XM radio since the first of the year and love it. About 70 music channels and 30 talk channels. I actually enjoy talk radio more than music, but the music selection on XM is outstanding. You can go to www.xm.com for more info.
I have a friend who is an absolute "radio pig" and he has both services. He thinks the sound quality of XM is better and that they have a more expanded play list on most channels. The Delphi home unit does a good job and sounds good in my big system. It is not up to the quality of the best CD players, but it images pretty well and is a big step above FM. Unfortunately, I don't know of an XM unit that can be plugged in to a dac.
