When CDs were young, they were often not very well done. Especially

Bop 'Till You Drop was the first major label release that was all
digital and it just does not sound very good. It's not hard to imagine

OT fell free to direct me to another tread if one exist .
Really old CD's can have pre-emphasise aplied they then the CD player
used its de-emphasis filter to counteract ?
( a rise in the treble to avoid noise in the recording equipment , the
subsequent damping of it in the playback system )

you know a way to regognises this a marking on the cd case , put it in a
25 year old CD player and watch the de-emp ligth come on ?
Is there a de-emp filter for foobar or dBpower amp etc ?

You are correct that it gets lost. Some rippers that detect it can add
a tag into the data, or apply de-emphasis, but there isn't a standard
tag (that I'm aware of) that allows automatic de-emphasis at playback.
The only defacto standard that exists is imho the FLAGS PRE info that
can be part of a CUEsheet. EAC detects and adds it a while now. I guess
foobar can add de-emphasis on the fly with a plugin on playback.
XLD for example couldn't detect it a while and implemented it pretty
late.
itunes applies
