Doesn't sound a lot like failure to me. Brute force technology (the only way they could have done this in the past would have been to sacrificially disassemble a Strad) looks like it has won the day.
“amazingly similar to originals in their sound quality”
I am amazingly similar to George Clooney. Hugh chunks of my DNA are identical, my internal organs are situated in the same locations, I have the same number of arms and legs, and I walk upright. Our hair color is even similar.
Yet apparently the few small differences that remain between us somehow keep millions of women from fawning over me.
Apparently ‘similar’ is not ‘same”.
