Well I wanted good sound in jr high as early as '73. Didn't but anything worthwhile until my inheritance in '80.
How long ago did you catch the bug?
My first inkling was about 1972 when a friend mentioned such things as Dual, Thorens, AR, Scott, etc. By '74-'75 I knew about all the Japanese manufacturers (courtesy of a military PX catalog) and about McIntosh. By '76 was using a hand me down all in one Panasonic compact system. The compact system did not last long and very shortly after, '77, came a "proper" 1970's system with such names as Pioneer, Kenwood, Shure, AR, Teac.
