We just need to accept that there are some very bad recordings and either listen to them at lower volumes if that helps, or just don't listen to them. That's what I do now, there is a ton of my collection that is so poorly recorded, or is hot mastered to the point where the music itself is just not rewarding enough to punish myself with, so I just don't bother with that material. I say who cares, it often seems to me that we cling to our old tunes like a security blanket and we'll try to adjust our rig to compensate for garbage recordings. I say stop listening to the music. If there are songs that the treble is so sharp it hurts, either turn it down, EQ it (which you don't like) or don't bother with it.
Once I stopped only liking my collection on hand it forced me to seek out new music and genres where I could find better recordings, and great musical content. That is how I discovered electronica which surprised me with just how enjoyable the music is, and how good it can sound. I love rock of all flavours, but so much of it sounds like ass (same with some of the old blues and jazz) and I have just learned to accept I don't like the recordings and only rarely will I listen to things that are punishing to hear. There are just so many artists and styles to discover that I won't waste my time trying to find a way to make a bad recording bearable; I mean come on, so much of this material (at least for me) I have been listening to for years so moving on isn't a big deal. I mean really, why limit myself to the same old tunes? Very boring.
