    Can't say I've noticed any CD's not sounding right, whether recent or going back to the eighties. Mind you, my newest player is getting on for twenty years old.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    Here's the EQ curve - it is 10dB but only at 20Khz:



    I'd expect this to sound like you'd turned up the treble control on the amp. Not 'correct' but not a disaster either, might sound 'too bright' to some people on some systems.

    It will change the sound from what was intended, no doubt about that. Trying to think if I do have any CDs from the 1980s that sound a bit thin and toppy, I might have a couple.

    Unless they are marked, how would you know which CD's need correction applied?

    most were not, so you would really need a machine with an indicator. there wont be many discs or machines that have the lamp around now anyway.

    As a Factory Records fan I bought the first UK (made in Japan) Factory copy of New Order "Low-Life" on CD.

    When years later I ripped it to Flac...

    ...it didn't sound right until I wrote a DOS batch file to process it with SOX to de-emphasize the Flacs.
