In the very start of digital some recordings looked fantastic on specs

just leave this hanging there....




** One of the first CDs I bought was of solo classical piano on the
Erato label. At the end of each track, as the final note faded down it
turned into a fizzing sound. This was noticeable at other quiet times
too.


It was also common practice on early CDs made from older analogue tapes to
have a steeper fade out at the end of a track than on the original vinyl
so you got silence between tracks. Never did see the point of that.


Tracks on analogue tapes are separated by a
three second leader (silence) so no fade of any kind
is required for either lacquer or CD mastering.

But, the 30dB lower noise floor on CD may have
given you that impression.
