Best Receiver?

Naim NAT01 I know it's only a tuner but probably one of the best ever made.

It's interesting that you ask this question, because I am questioning why I have a receiver with all of the streaming options available today. If you really like a particular radio station, you can stream it, too. 

I have a vintage rig with a Fisher "the 600". I love the way the tubes glow! All 22 of them! There's no quarts lock, so I can tune in stations from way outside my listening area. Albeit, not clearly... Anyway, good luck with your search! Have fun!

OP

erock79 mentioned the Fisher 800-C. A bit rarer than the 500-C, but several available.

It is the 500-C with AM tuner added. I had one, same dead quiet operation. 

I traded it to a member here to get my Mitsubishi LT-5V Vertical Turntable in my office system.

The tuners in the Better Pioneer receivers in the mid 70’s were very good. Overall, I really liked the best  Tandberg Units of that era, very nice sounding & high build quality.

Properly restored Fisher 500c. Match 7591a’s in unit and  either Mullard or Telefunken ECC83’s in the phase inverter and preamp sockets. Bliss.
