Yo-Ya Ma's cello
Yo-Yo ma has a Strad cello and, while he says it is a prvilege and honour to own it, he doesn't regularly play it, because even Strads, restored and protected, have a life-span. Modern instruments are now as good or better than Strads, but it will take a few hundred years for these makes to earn the same reputation.
Strads Amatis etc are beautiful instruments to look at. I am always sad when I see one behind glass in a museum, but I do think their playing days are fading.
