There’s a lot of mystique to this stuff. If China starts putting out sub-$100 Strad sonic copies, no matter how good they sound, it won’t even put a tiny scratch on the market in the historical instruments. Though a lot of amateur fiddlers will be tickled.
I kind of wonder, if there were “improvements” to the sound a violin can make would there eventually become a new standard? As you say, the Mystique factor could play a large part in whether or not the sound would be considered an “improvement”.
One of the few American imports into China (and Japan) are Fender and Gibson.
