MOST people have never heard great FM ...
I think that's true. Even among audiophiles, many who buy a pricey tuner won't go to the trouble of adding a proper antenna for their location. With FM, the antenna can be as critical as the tuner itself.
I'm still using my McIntosh MR-80 that I bought back in the late '70s. There are still some bright spots on the FM dial, and a good tuner can make a big difference.
