Sirus XM Radio

IME, Sirius Xm is better suited for cars and boats.  For a home based system, there are better and less expensive streaming options.  The only caveat I would mentioned is that if you listen to a lot of talk type "shows", then Sirius is an excellent option

If you want to listen to XM at home, streaming the signal will give you much higher fidelity than what you can get from the satellite. It may not be "high end" sound, but it will walk all over the fidelity from OTA - it will be immediately obvious to you.

XM subs now include the stream at no extra charge, so it’s really not a bad value.

XM satellite to car is compressed and boomy-- almost unlistenable.  There is lots of content, but boring repetitiveness of playlists on the dedicated channels like Grateful Dead, Petty, Pearl Jam, etc.  I'm getting much better SQ and choices with a 512GB USB stick of CD rips into a BMW Harman Kardon system.  We've come a long way from 8-track tapes...
