i had an old sansui tu-3900 tuner. it was descent considering that it was towards the bottom end of the sansui tuner spectrum. if you want an excellant tuner, try to find a sansui TU-X1....they aren't all that easy to find and generally go for around a grand. often considered one of the best tuners.
It doesn’t take much looking around to see that new tuners have pretty much been relegated to the high end and low end – not much in the middle anymore.
I have a Yamaha TX-950. Very highly regarded. I really never use it ’cause I don’t have much use for radio, but I’ve heard several people comment on this tuner’s sound approaching CD quality. Lots of trick features – dual antenna inputs, analog-style fine-tuning, wide and narrow modes, RF attenuator, etc. You can manually set up the parameters for each station and they are recalled when you tune that station. Or you can let the automatic feature do all that for you. It will probably set you back between $2-300 on e-bay. List price was $425.
The T-1000 and T-85 models also are good tuners, judging from their bid activity on e-bay. Typically go for under $200
I also remember the Onkyo 9090 tuners getting rave reviews in Audio back in the day.
I use a Magnum Dynalab FT-101A, audioadvisor price was $750 when I bought it a couple of years ago, has gone up since then however. This is a great tuner, has analog tuning capability which is much better than digital, IMO.
If you are looking for the inexpensive route...find a decent old stereo receiver from the 70s/80s (with a tape monitor loop.) The analog tuners seem WAY better than the poor ones that come with the digital receivers today in my experience. Of course you sacrifice remote, presets and digital tuning.
