In the heydey of FM radio (60's and 70's) it was a very important source in hifi-landia, and many manufacturers (especially the Japanese mass market companies) went all out to build state of the art tuners. Today, very little effort is directed at FM tuner design. There are so many vintage top flight tuners available at very reasonable prices that I have had never any interest in exploring brand new "hi end" tuners.
I am lucky to live in an area with 5 non-commercial stations (commercial stations have become unlistenable.) I have three vintage SS tuners (McIntosh MR-78, Marantz 20b, Pioneer TX-9500II) and one digitally synthesized (Sanyo Plus T55.) Right now the last one might be my favorite, and it cost me $55. It may well could be bettered by a Magnum Dynalab or vintage super tuner, but it (and the other three as well) sound like music to me so I am happy. (The hobby being what it is, I would like to get my hands on a good tube tuner, however.)
