To all:

Forgive me for butting into a conversation half way.  I personally do not 
believe Yamaha makes "junk" pianos for their Japanese clientelle, and better 
pianos for us.  That would be defeating their "traditional honor" that the 
Asians are so famous for.  It is my understanding that Yamaha makes pianos 
for three different wood moisture contents, corresponding to three different 
areas of the world.  (Please understand that this is not a defense to 
Yamaha's recent position, only hear-say from a reliable source.  If someone 
has other information, please share).  They make pianos for the 6%-8% wood 
moisture content (42% r.h.), 8%-10% wood moisture content, and 10%-12% wood 
moisture content.  The 10%-12% moisture content stays in Japan, and the 
6%-8% comes to us because the average household relative humidity is 42% 
(6%-8% wood moisture content).  This is supposedly why Dampp-Chaser makes 
their humidistat (for this country) to correspond to the 42% r.h., and their 
humidistat for other countries (i.e. more humid environments) to a higher 
r.h.  If this is true, then pianos that were made for a 10%-12% w.m.c. would 
adversly dry out when exposed to the "typical" 6%-8% w.m.c. of the USA.  
Some symptoms are listed in the recent Journal article.

Again, this is only my understanding.  If someone has more information, 
please respond.
