That's fairly common with digital recordings. Details and dynamics in the "presence region" can be too harsh unless you can find a quality remastered version. It's possible to alleviate most of that by carefully matching components and some tweaking.Depends on how much it bugs you if you want to put in the effort. YouTube is so compressed that it can be easier to listen to.
noise distortion for certain tracks
One CD has a couple songs with high notes (female, recording from the 60s) that brings out a pitchy, fuzzy sound like an extra track, a nasal tone, like if I put a napkin in front of the speaker. (sorry for the lame explanation, if anyone can tell me what I am trying to say that would be one helpful step too :)
I swapped speakers, amplifier, bought the CD again. It’s annoying and I don’t know if it’s "natural" meaning I can’t get rid of it.
Not happening with PC and attached speakers, when e.g. playing from youtube.
