Best vintage receivers for FM?


For 2nd or even 3rd systems (inc. my workshop) I am thinking of buying an older receiver or two. Most of the listening time will be FM stations...and even in 2nd type of systems I do want good sonics....my FM listening has been on tuners like the MD-108 and Sansui TU-919.......so-so sound is not o.k.

What do you think of the following list of candidates, or can you suggest others?

1. Yamaha CR-1000 or CR-2020.
2. Sansui 9090 or G-9000.
3. Nakamichi SR-3a.
4. Sony STR-6800SD.

Thanks.....

Thanks for the input so far....if possible, please be specific with models and your experience with them...1st hand info is usually best.

Thanks

Harman/Kardon 930. I feel has one of best tuner section in a receiver and is better than most separate tuners.
The following site may help you www.fmtunerinfo.com scroll down left hand side to shootout.
I've had several and ended up with a McIntosh and of all things, a digital MR 7082. I find it fits the bill for DX ing and has a very satisfying non-tuner sound. Go to the link I have listed for what they call the tuner shootout to see how they stack-up to the seemingly Sansui top dog.
Don't forget a good antenna. Good Luck,
