Viohazard tried a Marcello Villa (contemporary Italian) violin that was way, way out of our budget range a couple of years ago. Viohazard was utterly swept away by the sound, and I was half wondering how to make the impossible possible when the shop owner rang to say that his assistant had unfortunately advised us the wrong price, and that the real price was much higher. I forget how much the "real" price was, but the "wrong" price was something like GBP4,500!
That was a couple of years ago, and I forget just how it sounded - I remember thinking that "like silk" was the perfect description at the time. The whole room vibrated with a burning, bright sound. Viohazard had already tried many violins at that point and liked several of them, but that was the first time he came out with expressions like "this or nothing", and didn't want to let an instrument out of his hands once he'd played it.
He couldn't bring himself to try any other violins for weeks after that disappointment, and wouldn't touch his own violin for a few days. Our local luthier eventually built him an instrument out of some old, unlabelled instruments. Viohazard calls it his "Old Mountain Man" because it's stubborn about releasing sound, but it has a strong sound when cooperative!
