    I remember seeing my friends dad’s first cd player. Huge jazz fan and it did sound great. Especially the quiet parts (No tape hiss or record pops) and easy to use. He bought a couple of cds of rock and man they sounded good.

    Every other media at the time required some maintenance to sound good. Records would scratch, those tape pinch rollers would need to be cleaned. Nothing was easy, cds were (skip forward with a button push). Cassettes still were the only way to record, better for portability and sounded pretty good (we did some a:b testing cd vs cassette as kids).

    Late 80s, cds were everywhere. I stopped buying records. At my highschool radio station someone got a ton of great records from his neighbor who was replacing with cds.

    My friends dad who liked jazz did lament that a lot of the jazz he had in record form would never be re-released as cds. Not digital so a lot of music lost to time and a format change.

      Early CDs were labeled as to the processes used, a 3 letter code As and Ds, so:

      AAD == Analog recording, Analog mastering, Digital media

      ADD == Analog recording, Digitally re-mastered, Digital Media

      DDD == Digital recording, Digitally re-mastered, Digital Media

      This is known as a SPARS Code: https://en.wikipedia.org/wiki/SPARS_code

      Your dad's friends should have imported from Japan --- they were big on Jazz, and a lot of my Jazz CDs have spines labeled in Japanese on one side and English on the other.

    For a thorough breakdown of everything CDs, here's Technology Connections playlist on the subject:

    If you can read German, somebody also wrote a whole dissertation on the subject of the CD's development history:

      One of the cool/obscure things is that the center hole exactly matches a then available coin because it made the development and testing easier.
