I don't know I would even consider that as a single blind test as the researcher said this to his subjects

"These are all fine violins and at least one is a Stradivarius. Play, then judge the instruments."

They should not have been privy to such detailed from the researcher that "all are fine violins" or " at least one is a Stradivarius" especially if the goal is to see if a Stradivarius is preferred. The subjects should not know ANYTHING about the violins even in a single blind test.
