First try a better cable....a Monster 3 f-connector cable is what I use. But I have Direct TV which has XM radio.
I run my Hughes receiver to my DAC using a Nordost glass optical cable....the sound is CD quality....especially on the HD sorround channels. The monster cable is a night and day difference over a generic cable.
