Amps from the 1980's -- What gear holds up sonically? Reliably?

Hi Everyone,

For me, the 1980s were a real "golden age" of amplifiers. Dr. Leach’s paper on building a low TIM amplifier had been widely distributed and relied on by budding designers, and lots of boutique brands came. It was also the era of the biggest of the Conrad Johsnon tube amps as well and the invention of the MOSFET.

For me, brands I cared about:

  • Threshold
  • Sumo
  • Perreaux (New Zealand, very pretty)
  • Tandberg
  • Hitachi
  • Kyocera
  • Nikko
  • Krell (of course)
  • CJ
  • ARC
  • Yamaha (professional)
  • Carver
  • Mark Levinson
  • Amber 
  • Tandberg
This was also the speaker era of Snell and Apogee and Martin Logan. I am not sure there would be a Krell today if it wasn't for Apogee's 1 ohm speakers.

I’m curious who is still listening to these vintage pieces, and which brands you think have stood up both in terms of reliability and / or sonics ?

I still have the Advent model 300 receiver that I use in a second sytem with small Boston Acoustic speakers. It’s well over 40 years old and never a problem! I also have the Advent model 400 table radio circa 1980 and that still works fine!
I have an EKSC (Electron Kinetics) driving Hales Transcendence 5's.  Two brands mentioned here, a nice combo!  Although I'd love me some Transcendence 8's.

I did have an original Electro Research A75, pure class A.  Sweet.
Spectral electronics were built to a different technical standard than most and featured a particular sound that was, and  is still largely is distinct. The sound of the Spectral amps of that era compare favorably to that of modern high speed amps, and if not abused, can be recommendable.
