[CAUT] Advice for achieving stability sooner?

[David Ilvedson]

I wonder whether it has to do with the amount of tuning a piano gets at the factory.   I see only new Yamahas (Japan and China) and it is amazing how pounding will drop the pitch, especially in the treble.   
Personally, I don't like to have to do that...wear and tear...on me.
