 I am still working my way through it, but the sections on piano and violin I have found quite interesting.  The article is not overly technical or mathematical.  Should be a good read for physical modellers.

There was, somewhere else, an article that also compared the sound of the Stardivarious with the modern violins, and it's been proven that modern violins are just as good. I really wanted to see them use someone like jean Luc Ponty to test these, but they used folks from various orchestras and such, I think, and they could not tell the difference.
 
The modern electric violin should be substantially superior in sound ability anyway!

There's brass I do not want to play!
 
Having been a tuba player, I can tell you that the psychology of playability (ability to play?) is based largely on the perception of how well constructed (or branded) the instrument is.  I always prefered the Meinl Weston with rotaries to the Miraphone.
