I think what you are proposing is correct… that if you want a speaker that is overall a high performance speaker… (I stay away from highly resolving as there are inexpensive high resolving speakers that sound terrible on other dimensions). You can expect high standards on all aspects of sound quality. The $12 - $15K category has some real good products.
I actually bought Sonus Faber Olympica 3 (~$12K) when I was approaching retirement… as my final speakers. Great choice, and happily after I retired I was able to upgrade again to the Sonus Faber Amati Traditional ($32K).
So, in that category you just have to audition them. They have very different house sounds. If you actually are looking for really high resolving… then Magico is probably your choice, but make sure you have the right electronics or you may not like what you hear.
So I would find places to listen to:
Sonus Faber … once retired you may also really appreciate looking at them.
Dynaudio Contour 20
Wilson
Magico
That would be my short list… if I wasn’t completely sure Sonus Faber is the sound I want.
