Old records were mono, not stereo. The sound was so warm. Amp had time (bass/trebble) knob, and volume, that was it
I remember listening to true quadrophonic music. OMG what an amazing sound… No, not 4 speakers, it was quadrophonic, completely different. I still remember listening to prog-rock on quad sound
I’m lucky in that although I’m only 50 this year, I experienced a lot of the old stuff… I was in that crossover! Old enough to remember Elvis, young enough that he died before I was 10! lol
