The first album out on CD was Sgt. Pepper's Lonely Hearts Club Band on 1 June 1987. The advertisements read "It was twenty years ago today."
So I bought the CD and a SONY Discman D-5 that day. The CD only came in STEREO. I had the MONO LP. As Kevin said, it was nice to hear the album without the pops but I thought my LP sounded better even when I played the CD through my stereo system.
The jewel box packaging was poor and unimaginative. They would have done better to just put the CDs in miniature cardboard sleeves similar to the LPs but those boxes were all the rage. It would be a while before we got box sets.
In those days, CDs were marked:
AAD- Analog recording, analog mastering, digital format i.e. CD
ADD- Analog recording, digitally remastered for CD
DDD- Digital recording, digitally mastered for CD
The 1987 Beatles catalog was AAD and in definite need of remastering. We waited a long time for that.
