Something I've been meaning to ask. New York Steinways, I 
assume? 20%RH at 70° puts soundboards at 4.5%MC. That's at or 
below (depending on who you talk to) what they were originally 
dried down to for compression crowning with flat ribs. There 
shouldn't be a lick of crown anywhere in these pianos in these 
conditions, and they ought to be mostly killer octave and 
sound thoroughly terrible right now. Do they?
