Radio Russ describes one of the great apex performers, the Accuphase T-100, which commonly sells for $850 or so on eBay:
The Accuphase T-100 is just awesome. It's a hand-wired work of art that not only had the best FM reception ever seen in its day, it also had a killer AM section. I pull the T-100 out of its storage box once a year just to bask in its radiance. I don't want to put too many hours on it because repairing it is beyond my current capabilities. Also, some of the FETs it uses are no longer available. My location doesn't present much of a challenge as far as adjacent channel rejection which the T-100 excels at.
The Sangean WR-3 may fall short in several other categories in an urban environment so my comment was based on its ability to pull in weak stations with very little noise using a non-directional, unamplified antenna. Sangean is making some of the best performing tuners available today and the WR-3 is their flagship model as far as I know. And why is it that jazz stations always seem to be the ones that don't come in clear?
