My first moment was in high school circa 1985 or 1986 when I got some Cerwin Vegas, a Pioneer receiver, and a Fisher CD player. I'd had boomboxes and consoles until then, and the step up was dramatic. My CDs came alive. I remember the drums on Rush's Power Windows (an early "DDD" recording, back when I looked for that kind of info), how they sounded so real and full in the intros for "Marathon" and "Mystic Rhythms".
