Best Receiver?

On the current market the Yamaha RN2000A and MAC7200 are your top contenders. Semi vintage, Nakamichi SR4A was outstanding. Deeper vintage, I rate the Sansui 8 Deluxe and Pioneer SX1250 tops. Really deep vintage I agree the tube Fisher stuff was great. A Marantz 15 was their best one. But vintage means trusting a restoration to be done right. 
If your pocket goes that deep, the Yamaha is the winner, with all the connectivity and performance you need today. 

Luxman, R-1120... I had an R-1050 that I truly loved until I heard the 1120. Just more of the same but had a tighter grip on the KEF, Ref 103.2 I had in my vintage setup.

You might try Carver, Emotiva and Integra receivers. Buy them used. A couple hundred bucks will get you a unit that sold for thousands. You can always use the preamp outs to drive a better power amp later on. You will still get the benefit of their surround sound decoding features. Happy Listening!

The Concept receivers were quite nice. The lower to middle of the pack units usually sell for resonable prices. Their top of line units can go for megabucks... Very nice all in one units.

If you are seeking a modern-day receiver, Magnum Dynalab manufactures one. Believe they still do anyway...
