Nice post, "3", takes us down memory lane! Following on from Peter (definitely, the Quads) I would add Apogee Scintillas: difficult to drive, but offering magic when well set up -- also a newish design concept at the time... and the little BBC LS3/5As monitors on stands (stands were a relatively new idea at the time, too). I'm sure someone can propose horn-loaded speakers as well...
TTs: the AR 101 (#?), the Linn LP12/Ittok (that's still in production)and the Goldmund Reference, could also fit the bill. Linn set the "start from your source" trend and, indeed, the TT was (still is) a good performer...
Old media: anyone remember the Nakamichi Dragon cassette player (then the "ultimate" in cassette reproduction), the old Revox R-to-R (can't remember the model #), and the open reel Nagras of the '60s?? Regarding the latter, sound reproduction was phenomenal (master tape level).
Tuner: the 1st Marantz stereo (made in the US). This had good reception AND great sound, by far superior to what radio had to offer at the time.
Amplification: MacIntosh 75 (I used to dream about that one), AR SP6 pre, the first classA Krells (by commercial standards of the time, they had super power reserves). M Levinson pre-amps: I remember the ML-6 (made before ML sold his name to Madrigal).
These come to mind now...
