Unsound is right: even one great, or even good, station makes a good tuner essential, and the range of quality in tuners is far greater than, e.g., CD players. Good FM analogue broadcast on a good tuner can be spectacular. Some of the best sound I have ever heard out of my systems over the years has been live concertcasts via FM.
Here in Tampa we have WMNF community radio which is a great eclectic music station, broadcasts lots of stuff live from their studio, and has superb alternative public affairs programming. -- available online BTW, and well as on 3 channels of HD radio, featuring different programming. It's one of the best things about Tampa bay area. It would justify a big tuner expense.
