i too listen to classical music, as i am right now as i am writing. timbre is number 1. dynamics are at the bottom of the list.
there is one speaker which is least inaccurate in the midrange, namely the quad 57. instruments sound natural and have most of the timbral cues to present a very realistic sound. yes, they have weaknesses and flaws. all speakers do. thus, i would select electrostatic speakers, to minimize timbral inaccuracy. i find most cone designs problematic as to reproducing timbre accurately.
