models CS 2.4 and up to the 3.7 are damn right scary at the accuracy of instrument 's inherent frequency/transduction.
I can still remember (vividly) my 1st taste of Thiel loudspeakers via the CS 2.4- after a few "numbers" to get acclimated w/ the speaker, I remarked, "I now know and understand Audio reviewers interpretation of instruments' timbre in time and space".
In other words, hearing the brass on horns or wood on the guitar body.
Such realism w/ these speakers.
