Satellite Radio & a DAC

Has anyone tried to refine the sound of Sat Radio for a desktop system or the like??

I have a Benchmark USB DAC and wondering if I should try and work it with a SIRUS radio...


Thanks, John
You can't put back what isn't there.

Isn't that what upsampleing does?
Dac's can't lock on to sat radio-yet.
i use directtv xm then into a deqx dac,much better sound then a xm reciever-they sound awful.
