Top vintage receivers vs. modern high-end equipment

I’m in my late fifties and have has so much gear throughout the years it’s silly.  Mac, Pioneer, Sansui, Phase, Citation, Krell, Levinson, Crown, marantz, etc.

Some pieces I’ve kept and swap in every now and then, but my go to does everything right is my Sansui 9090DB.  It’s so smooth, has grace and power. I can’t find any sonic shortcomings.

My audio buddies are always amazed at just how ‘good’ it sounds. 
Just the right amount of everything.  My second favorite are my vintage marantz preamps.  

I bought a Mcintosh tuner 7082 and the tuner doesn't work, either do the presets. they claimed to put new batteries in the unit. after charging for 24 + hours still no luck?  any ideas?

Im surprised that no one has mentioned the Harmon Kardon Twin Power 730 or its smaller brothers, 430 or 330. I bought one in '78. I recently fired it up and was shocked at how big the sound is.

I'll second the Sansui 9090 series.
I have the DB version and over the years whatever I pair it with shines. Occasionally when a meet a repair tech at audio shops and discuss various equipment, when I let them know I have the 9090 they all tell me don't ever let it go. Some claim  magic comes from power transformer, others say who needs tubes when SS sounds like this.

I have a Heathkit 151a integrated redone by Sam Kim and can't believe how sweet sounding it is.  He uses only the chassis and transformers and completely builds the amp from the ground up.  MC and MM phono sections.  Incredible linestage. If 8 watts work you can't do any better.  Google Sams Audio.
