I don't think I can remember them all but I remember my very first acquisitions quite well:
1973 - Pioneer 25-watt receiver.
1976 - Pioneer 50-watt receiver.
1978 - Yamaha M4 and C4 separates.
Law School 1981-84 - went back to Pioneer 25-watt receiver.
1984 - Kyocera receiver to match new Kyocera CD player.
Later in the 80's - Rotel amp and preamp, followed by British Fidelity A-370 amp and MVP preamp, then ARC D-300, followed by Goldmund Mimesis 29 and Ayre V3, finally replaced circa 1999 by my current ARC VT-100 Mk III which is a keeper.
