I'm listening to sirius on my free 3-day internet trial period. I got one for both sirius and xm to compare. I'm definitely leaning toward sirius, but my question is this: The sound quality on the internet stream sounds like absolute shit. Probably equivalent to a 56kb/s mp3. I'm assuming its just compressed a lot for the internet stream and that the actual quality when I buy the receiver and hook it up will be much better. Am I correct in my assumption? If not, I really see no reason in even bothering to get it. Also, when I do become a subscribing member, does the internet stream get become better quality as well, or will it stay the same? Thanks.
