I have Direct TV with all the music stations. Not inspiring. Although I have a very nice audio system, I did not want to spend big bucks for a new tuner, since it would not be my primary source. I purchased a Fisher FM-100B tuner a couple of years ago for $100 and have been extremely happy with its pleasing, musical sound. Although I have not touched it, I believe a complete tube upgrade can be had for around $200. As far as I am concerned, this route cannot be beaten.
Good luck.
