Really, it's only effective at showing how violins compare when being played by blind musicians in hotel rooms, while being observed by researchers. But at some point you have to stop finding caveats and find some evidence for the contrary position.
What is the contrary position? That older violins have some kind of superior magical design that can't be replicated? Has anyone validated the claims for why these old violins are supposed to be better?
Well, I don't subscribe to the idea that old violins are better than anything we can make... but you can't simply compare an adjusted violin to an unadjusted one.
