I recently heard some Audio Note AN-Ks that were much less bright than all the speakers I've heard recently. However, if something is mixed really badly, you will hear it, but my impression was they announced the "badness" of the mix without making it painful. They did not screech on well-recorded violins for instance, but a track with a lead vocal that had way too much "brilliance" on it was clearly audible as such.
I listened to ProAcs in the same session and by comparison they were certainly more analytical than the Audio Notes.
