Since then, his results have been duplicated and/or improved. The name Stradivarius still carries an amazing amount of weight. Researchers have shown musicians can't actually differentiate between newly built violins and Stradivarius:
"The duo asked professional violinists to play new violins, and old ones by Stradivari and Guarneri. They couldn’t tell the difference between the two groups. One of the new violins even emerged as the most commonly preferred instrument." [ 2 ]
Therefore when TFA from NYT makes this vague, unsubstantiated claim "For hundreds of years, the best violin players have almost unanimously said they prefer a Stradivari or a Guarneri instrument," take it with a grain of salt or preferably evidence that mainstream media benefits by perpetuating mysterious illusions for the emotional allure.
