None of you explained the mechanism, only why it is a good thing. I agree it is a good thing. After thinking about it last night (what I do in the dark before sleep), I decided maybe it has to do with how music is encoded in the groove vis how the stylus contacts the groove and is thus able to translate physical undulations in the groove into an audio signal. The relation between the stylus geometry and those undulations might be the critical factor. I could imagine how that might effect what some would call "timing". But I don't think it's really timing by the formal definition of same.
Also, I commend you (plural) and anyone else who can confidently distinguish first order harmonic tones from the fundamental. As a (part-time amateur) singer, I can tell you that is no easy thing even in a live venue. The brain doesn't really care a lot about that first octave of tonal difference. (Why sometimes if my pianist starts out an octave too high, I will go right along with him, until I realize that the high notes are going to be out of my vocal range.)
