My examples are mostly on the bang-for-buck bargain level at the time, but all remain excellent components to this day, yet I have no doubt modern technology has improved on most. Here's a few off the top of my head:
Sansui TU-717 Tuner
Bedini 25/25 Amplifier
Quad ESL 63's (second that one)
Klipsch Heritage Series (not actually a product of that period but probably the apex of their production).
B&K ST-140 Amp
NYAL Moscode products (various amps and preamps during that period - I can't recall all the models I heard back then, but all were quite outstanding to me at the time)
Audible Illusions Preamp (they improved on it since then, but the early ones were great at the time)
AR Turntable (the reissue of the classic version was right around that time - great table for the money)
Grado Cartridges (Joe Grado made a great sounding MM cartridge affordable)
