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 ?

Hey Boxer - you wouldn't happen to have one of Jeff Korneff's 6bq5 integrateds would you?  I had one many years ago, sold it to someone in Washington state who was using it with Klipschhorns.  What an amp!  I now have a couple custom SE int amps built by Ed Duda, the chief amp designer of the old Lafayette Radio Corp....  And yes, what a hobby!!!

Lou - Nope, mine is a KT88 SET stereo amp with a total of 5 tubes. Two Kt88's, two EL84's (6bq5's), & one 5ar4 rectifier tube.The amp is very good. That stated, I wouldn't hesitate to buy anything he has made. Jeff is very approachable, I've talked to him a couple times over the phone. However, I don't think he is building or designing anymore, unfortunately.

I'm with you, I wouldn't hesitate on any of his designs either.  I had one of his early 6bq5's.  

Can you post a picture of it, I'd love to see what it looks like.  Very interesting with 6bq5's for input tubes....

I concur that the Hafler (DH-220) holds up sonically, and reliably.

A couple years earlier (late 70s), the Tim de Paravicini Luxman tube MB-3045 holds up sonically, but NOT in terms of reliability. His SS preamp, the C-1000, does in both respects.
