Was driving my Volvo XC60 the other day, and noticed that the Sirius-feed from their new geosynchronous satellite pair sounded noticeably better. Much more dynamic range and increased frequency response for the music channels. Also, gone was the swishy high end with high hats and cymbals. Their talk channels sounded about the same, but those are limited bitrates coming into their plant anyway. Seems like the Sirius audio better matches what's been the superior sounding XM side.
Well done!
