What did your system look like 30 years ago?

Interesting thread.  Back then I had Duntech Princess loudspeakers, Audio Research Classic 150 amps, an Audio Research SP11 Mk II preamp, a Vendetta Research phono stage, a Basis Ovation turntable (had just gotten it, still own it) with a Graham 1.5T arm and a Transfiguration cartridge, and a Krell MD 1/64SBX (not sure of the model designation, it was then their best DAC) DAC combination.  Cables were a hodgepodge, but I did have very short Siltech speaker cables.  I think I may have replaced the ARC preamp with a Jadis JPL line stage in the summer of that year--the start of my descent into all tube electronics.

Denon PMA-757 Pre-main amp, B & O Beogram TT, Canton Karat 200 speakers, Nakamichi BX-150 deck, Denon CDP. Good times!

Circa 1991, and the only system in my house at that time:
Harman Kardon HK795i receiver 
Technics SL-230 turntable
Stanton 500 cartridge
Sony CDP-110 CD player
Harman Kardon TD212 cassette deck
EPI 1200 loudspeakers

Most of the current audio equipment that I listen to these days is vintage, with the exception of my DAC’s. The electronics are vintage vacuum tube. The speakers are AR, KLH, and EPI. Almost all my current equipment is older than the system listed above from 30 years ago

I still have the HK 795i receiver, TD212 cassette deck, and Technics turntable. I am just now trying to sell the HK795i. The TD212 is still around in case I want to listen to old cassettes, but that is a very rare occurrence. The SL-230 turntable is still very much in use and is now mated to an Ortofon 2M Red cartridge. It is one of a number of turntables hooked up in my basement audio systems.
