I use my DirecTV coax digital out to my Bryston BDA-1 DAC. It works reliable, however the sound quality is so-so. The internet radio channels on my Apple TV sound much better.
It's certainly possible for the music channels to sound excellent, before the Sirius XM merger, the channels that DirecTV carried were different, and some of them just sounded fantastic. Unfortunately, it's now all heavily compressed, and well, better than nothing.
TV shows can sound quite good, and of course you can output sound in Dolby Digital, so for TV shows with a Dolby Digital processor, the sound quality is quite good.
