I read that article a while ago and it rings way true to me.
I'm a trained Cellist. I have met Yo-Yo Ma, and he invited me to play his Stradivarius Cello, The Davidoff Stradivarius (
http://en.wikipedia.org/wiki/Davidov_Stradivarius), or at least the cello he used to play.
It sounded great, but that's because it is a really well made and maintained instrument. There's absolutely nothing to all that "mojo" ****. Either an instrument is well made or not. Older instruments are worn in pleasing places like wood edges smoothed over and the like. That is most of what people feel as "vintage mojo."
My current cello is a cheap student model that cost about $1000. Nobody has ever said it looks nice, but plenty of people have complimented the sound of my playing.
I'm also a carpenter, and the adage "They don't make them like they used to" is true there too. Old houses are a nightmare of crappy construction and take tons of money to bring up to modern standards. They last cause people spend tons to keep them looking original.
So, all this Vintage Magic stuff is just humans NEEDING things to be better. They aren't. You can get a bass for $500 and get it playing 100% as well as a $5000 vintage instrument.
