An effort to recreate a 'concert hall experience' is a great way to put it. So, whatever it takes. We don't want flat sound, that's for sure, we want it to be three dimensional.
Yes, I don't care much about too sharp imaging, it feels artificial, it's got to be balanced and somewhat diffused.
Ideally, one system for all kinds of music, in reality - no, too expensive, requires very big room and swapping in and out certain components.
My modest system tailored to reproducing vocal and acoustic guitar more or less realistically. Also for ambient and tribal ambient music. It is not bad for jazzrock but not good either. And for big orchestra performance - forget it, can't handle it.
