Apologies for ressurecting this thread. I just couldn’t resist. 
I’ve spent some time reading most of the comments while discovering a few albums to listen. Thanks for that. Btw, listening to Boulez’s album as I type. It does have a generous dynamic range.
Dear Google Play Music subscribers – and I think @pwjazz is one, if I’m not mistaken – do you have any public playlists to recommend (or radio)?
I mean, before reading this thread everything orchestral, Bach, Beethoven, etc, to me was Classical, but then subcategories emerged and I felt ignorant to the point of start losing interest on it. Ignorance is indeed a bless sometimes. 
I just want to hear some random good “classical” music. But at this time ignorance is a burden because I don’t know how to find the good stuff. Analogy here is: teach a regular consumer why (s)he should (or not) buy a Sku||candy headphone. 
Anyway, I’m glad I learned something already. I’m aware this is going to be a long (and slow) process. 
I’m not in a rush anyway.
