Just imagine a so called „Stradivari“ on auction. And the people with measuring tools say: „Well, the tree grew in the 20th century anywhere in Northern Europe, the painting has modern components unknown in the beginning of the 18th century - so it can‘t be a real Stradivari“. And the participant of your listening test says: „It‘s a real Stradivari! I heard it! Human ears are better than measurements!“ How much would anyone spend for the violin in the auction?Listeners had the same preference for modern violins as the players, so no, you don't need any of this; you only need the sound. And as @rjp mentions, you can likely even train a model on it to distinguish a Stradivari from a plain violin with high confidence and accuracy.
You may look around Wikipedia or elswhere which modern musicians played or still play Stradivaris. Gidon Kremer did as well as David Garret. I am sure I can find out who plays just by listening, not because my ears are so good, but just because they play in totally different styles. Though I am also sure I shall never find out by listening whether one of them plays a Stradivari or any other violin. It just doesn‘t really matter.
