I know your anxiety. I sometimes have that same problem that you have, even including, at times, piano that sounds a bit ripe.

I would follow the suggestions as earlier mentioned (especially the slow rpm test) and see what results you get. If you still do not obtain the results that you expect, then, in short, you might have to change your expectations (as I have) of what you can get out of vinyl. I mean that in a polite way.
