Monitor Audio for classical music

The problem is the state of most classical recordings. They usually have flaws on the harsh, overloaded side (big dynamic range of classical, especially orchestral, strings are hard to record well, horns, crescendos) so a cool speaker is likely going to be fatiguing. Are you buying new? What price range?

Is thin-sounding speakers OK for classical music?

Monitor Audio speakers use metal dome tweeters and metal cone woofers which in my experience don't self damp well enough to be true to (classical) instrumental timbres. Put another way...the drivers ring (like bells) and color the sound in unacceptable ways.

Ideally you want drivers that self-damp well i.e. fabric dome tweeters and plastic or paper woofers.

I think Spendor and Dynaudio complete speakers sound excellent with classical. Both lines have the type of drivers that I described (as working well with classical).

Having had various Maggies for over 30 yrs they do most everything required for Classical well.
The glaring exception is they lack the dynamic range to reproduce a symphony, classical music in general is much more dynamic than rock.
I am reminded that they just don't "breathe" everytime I listen to the KEF Ref. 3.2's in my bedroom.

My aerial 10's use metal dome tweeters that do not ring like bells. I consider them very well balanced and natural speakers that are not ideally perfect but almost OK for classical music.
for classical music the only monitor i can think of is actually headphones otherwise large speakers are encouraged.
