How does it sound in all areas of the scale at all dynamic 
ranges? Is there both crown and bearing in the killer octave? 
Panel cracks aren't a reason to change boards if the original 
is working, and the presence of cracks isn't an indication 
that it's not. If there's no bearing or crown in the killer 
octave, and a hard blow in that area distorts into garbage in 
the attack, you need to fix his budget first.

We can't diagnose it on the list. It needs to be done at the 
piano.
