<br>Very usual are damper spring strength, how soon the dampers engage,
and even jack return springs. Hammer butt springs can get into the picture
slightly, friction of course. Outside of that you are going to have to
look at key weighting and leverage... tho Yamaha should be pretty consistant
on those points from piano to piano.
<p>You might also check to see (as a long shot) if for some reason the
upper action mounts are screwed in equally on both instruments. Not likely...
but you never know.

<br><font face="Arial, Helvetica"><font size=-1>I have 2 pianos sitting
next to each other. Both new Yamaha P600 45`` pianos. One has a much
lighter touch (action) than the other. Can you give me some reasons
why, and is there any adjustment that can be made to stiffen up the lighter
action?</font></font>
