The latest experiment was just reported by Strad Magazine. They took some professional violinists and an assortment of modern violins and strads. The violinists were blindfolded and used their own bows. One test was to see if they could tell a strad from a modern instrument. The correct and incorrect guesses were about even...so, no, they could not tell. Then they were asked to choose the best and the worst after playing them blindfolded. The top two chosen as best were modern. The third was a strad. The worst was a strad and the next to worst was a modern.
