Quite so. I'm curious though. Have any of you found action 
problems you could attribute directly to setting a piano up on 
the lyre? Any actual evidence of key bed damage from this? I 
never have, but there are still an infinity of places I 
haven't been. So I was wondering if this is real, or yet 
another of those "intuitive" things. I know broken lyres and 
crushed corners on bottom plates are real, I'm just wondering 
where all this concern for the key bed comes from.
