10 professional just come and play. They won't care about whether violin was under good care or not. If the violin was taken care off, given then age of the wood. It will suppress all the newer ones. If you play guqin, you can easily find the hundreds year aged wood on the market. People prefer that kind of wood. Because of the abundant of such wood around, won't cost a Stradivari unless you wanna buy ancient one like made in Song dynasty era.Care and maintenance is a reasonable objection but unlikely given the venue. The panel was 10 professional (i.e. do it for a living) soloists. I know it's hard to accept certain myths that you have held dearly all your life dashed before you, it has happened to me several times, but science doesn't care about our feelings.
