I personally think it depends on the source. I'm not sure what bitrate Sirius broadcasts at, but my recent experience with Sirius in rental cars is a joke. I find anything except for talk radio to be almost unlistenable as it is so lifeless.
Conversely, my XM unit at home sounds more consistant with what I would guess is a 128 bitrate. Certainly more dynamic range to be found there.
Also, don't rule out the possibility of a variable bitrate being broadcast, which is even worse (likely to average 96bitrate) and makes cymbals sounds underwater and bass non-existent.

Amazing sound for free. Keep in mind their recording pratices are/were at the top of the game.
