Theo,
Go for it. Adding a dac to sources such as DTV, Apple TV and XM Radio is a great addition. Of course do not expect anything near sonic nirvana, but for just listening to hassle free music, I believe that it is a perfect way to go. FM radio is my first choice for casual listening but with good stations becoming harder to find, one has to make do with what is available. Unfortunately that availability is presented to us in the form of nasty little digits. Fortunately, one can make all those digits sound pretty good. You have the right idea wanting to grab onto those little digits and making them sound halfway palatable. Look for an inexpensive "TUBE" dac for the best listenablity ( IMHO). I believe that I have found a very good one with the new Jolida Glass tube dac. It has all the right inputs and sounds great for a fairly low cost... A bit under 500.00 new. It uses 2 12ax7's for the output. It is VERY high quality using Clarity Caps and high quality connectors. I run a high quality Toslink from my Apple TV directly into the Jolida dac. It turns the little digital machine into a highly listenable item. There are a smorgasbord of radio stations to choose from and it really makes listening enjoyable. Of course there are many other Dacs that may even be a better choice for you than the Jolida.
I believe that you should most certainly give a dac a try with your system.
Good luck
