I don't see how you can say this as, for instance, the music of the Indian subcontinent uses a very different system of a) tone fractions and b) beats to Western music.

And we have 12 bar blues.. off course variations exist.. but the 16 beats of the typical Indian subcontinental style still fits the 4/4..of the normal western-world. Point is that the development of music and rhythm is profound and not only related to culture...Its rooted deeper and attached to emotions to sex..It's a fundamental...! this talking to something deeply rooted inside us is what artists try to put on their records and what we try to decode out from the recording again right in our living room...

AIUI, Western music is 7 tones to the octave? Do ray me fa so la ti ... right (as anyone who has seen The Sound of Music" will know)?

Whereas Chinese music, I believe, uses a 12-tone scale.

This is nothing to do with "12 bar blues".

if you take the black keys there's is 12 pr octave....But that's not really the point...it's more that music is profound and developed with similar structures regardless origin..It goes a level deeper than culture and it's linked to something deep within. If this common denominator is found we may have a clue how to make systems perform better...

I also know a local amp builder that can not hear any difference between chinese low cost carbon resistors and naked Vishays.
Well, if you think that resistor type would make a change in sound, then you will agree with my point labeled "Point #4": If there is indeed a change in sound, perhaps it's not due to the theoretical 40pF change in capacitance but to something else related with one component (capacitor) vs the other, or some additional change at the electronic (signal) level.

Can you justify the adoption of 7.83Hz over the 1/64 of 500.5Hz (=7.82Hz)?

yes!
in general no one really set the frequency noise, so she changed Russian, Czech and German scientists believe it = 7.83 Hz. American, Japanese, English = 7.82, while the Chinese are generally = 7.5 Hz. (I have the consistency of the Chinese electronics but!)
I relied on the Russian standard. That's the way real-time noise frequency in the air. Its fluctuations determine the conditions of the recording studio. Little nuances but ... it has a terrific sense of presence (or lack of) live music!

I think you are saying that these Countries adopted a different recording standard. I'm OK with that.
All that needs is for the "standard" to be printed on the recording so that we listeners can switch the replay curve to match the recording curve.
But that is not what I am asking.

I am asking: why adopt 7.82 or 7.83 or 7.5 or another other fixed "standard"?
If the replay curve exactly matches the record curve, then does it make a difference to the final sound whether the "standard" adopts one value over another?

Another way to decode the riaa-emphasis is to use software filters. I have such a system running since a few month, actually using the biquad coefficients provided by Scott. Yes, it is ADC -> software filter engine -> DAC during playback. The result is amazing.
It can't be that difficult to compute the coefficients for those mentioned other curves. Perhaps somone knows how to obtain these by the aid of TI's coefficient calculator?
I seem to miss some understandig how to adjust the parameters to get along...
Or is it possible to compute those coefficents out of a Laplace transform?
