My $7 vintage Sansui tuner from eBay causes jaws to drop when people actually hear the thing. Get a good fidelity jazz broadcast from a public radio station or college (either can be found like below like 91.9Mhz FM or so on your dial). The trick is you need an relative uncompressed unscrewed up signal, and commercial FM isn't it. Some of those broadcasts rival my redbook front end for all of the audiophile critia, including musicality. Now that's scary. And remember, this is a used $7 solid state tuner from the '80s folks! I would seriously consider a respected used, vintage tuner before buying anything new. And like my $7 jobby, you might not need to spend all that much. The lucky part here is most people live in an FM waste land, so nobody needs or wants a tuner. And their loss is your gain. I would not buy a brand new, or current production model tuner. To me the value just isn't there. But maybe you listen to way more quality FM than I do?
I would purchase an analog vintage tuner if I were you. Also, you will need a decent roof-mounted aerial if sonics are important to you.
