Satellite radio tuners

My hard wired computer/streamer could access Sirius/XM. Did not do a lot of critical listening (if any) but I was happy with what I heard. Listened to more sporting events than anything else.  Golf, NA$CAR, college and pro football. I watch very little television. 

The BlueSound based systems handle streaming from Sirius/XM.

You didn't give any details about your two channel system but if it will take an airplay stream that is your best bet.  Sirius bandwidth is < than what airplay will process so you won't lose quality from your iPad. 

Kenwood made a standalone Sirius/XM only tuner. I have one in my system. I don’t use it very much anymore, but it sounds pretty decent.

ST-7000S is the model.

I had a Polk dedicated XM streamer.  Came with it's own antenna.  It's gone now, XM for the car only with all the better resolution options inside.  But I do still discover new music while driving on XM.  I snap a quick pic and then look for it later on Qobuz.
