Interesting question. But surely, the answer will differ between individuals, and even for the same person with respect to different experiences and tastes. Was the first time you had sex the best time? Are you still "chasing after" a repeat of that experience?! Has your palette (for fine wine and food) not improved with age and experience? I loved JBL when I was in high school, too. And Corvettes. With age and experience, however, I came to appreciate subtlety and finesse, both in hearing and handling.
Which is not to say that I don't still have fond memories of those various "first times." But nostalgia is one thing; "chasing a sound baked into my brain from an initial experience"—well, that would be unfair to the second experience, and the third, and.... The question is really about what a "person" is. Am I the same person I was in high school? Yes...and no. I've learned a few things since then, and learning means altering one's perspective in various ways.
