Agree with Al.
Fundamentally I think it has more to do with mic placement than anything else. Close microphones reproduce high frequencies and low level overtones that we never hear live. Can't think of a single occasion when I attended a live performance and heard screechy violins, even in a chamber. And, FWIW, I have found the balance between the strings and the rest of the orchestra on many recordings to over emphasize the strings, especially the violins.
