>whether there are any real, noticeable physical differences between the sound produced by a Strad and that produced by expert modern luthiers.

Isn't this trivially true? I'm sure if you hook up both cellos to a bowing robot using many permutations of contact point, fingering, speed, pressure and angle, and record the sound, it would be possible to consistently discern them through spectral analysis or something. Is the claim that if an expert modern luthier reproduces a stradivarius he can get it so close as to measure identically?

edit: by the way

>I agree with everything you've said. It's also completely irrelevant to the question at hand, which is whether there are any real, noticeable physical differences between the sound produced by a Strad and that produced by expert modern luthiers.

I don't know why you would say my post is irrelevant to that question. You said "people should be able to hear the difference in that sound in blind tests", and I'm saying that the difference between two cellos could be more complicated than just listening to one after the other for some minutes and filling in a questionnaire.

I guess another way of putting it would be that the aura of an instrument that elicits a more sentimental playing of it by the musician is sort of not really interesting or relevant because you can just lie about any instrument to elicit it.

No, I am not talking about aura at all, I'm just saying that the physical, measurable sound that an instrument produces in response to being played, physically and measurably, could have more subtle effects on artistic performance (as a consequence of the physical vibrations of the object and the way those vibrations respond to the player and vice versa) than those that could be elided in an afternoon of A/B-testing under the banner of "stradivarius myth DEBUNKED".
