My conclusions? If the problem isn't severe, go for it. But you won't
get any joy out of trying to fix something really nasty.

The problem for me is EMI recordings of excellent performances of classical
music by favourite artists that have a sound quality I don't like. This can
certainly be endured and 'listened though'. But given the flexibility of
what I could try, I have become curious. So wondered what others may have
tried already and decided.

My conclusion is that you should get a Linsley Hood amp from the 1970s
and play with the switched frequency bass and treble controls, and the
switched frequency variable slope treble filter until you get bored,
then put everything back to flat and just enjoy the music.

I already use a Quad 34 whose 'tone controls' I modified some years ago. I
do alter the settings depending on the source material. Although most of
the time I keep to the same settings that give a better response from
fairly flat material and measure closest to flat averaged over a reasonable
frequency bandwidth. The problem is that I don't think normal 'tone
controls' really address what I was curious about.

When I get a chance I'll experiment with this and see if anything emerges.
But Don's comments do chime with my feeling that this may vary too much.
Although I have the feeling that a fairly simple common alteration might be
useful for some old EMI reissues on CD. It may well be that I'm just
hearing the effects of messy multi-micing, mic resonances, etc, and so
impractical to deal with. But I am wondering, for example, if a dip in the
few kHz region may make some of the poorer examples sound better.

Slainte,

Jim
