Greetings,
The first thing I would do would be to check the hammershank pinning. I'll
bet a brand new mute that you will find 90% of the problem right there. This
isn't uncommon on new Steinways. There will be the occasional whippen center
that is also too tight, they are easy to check with all the hammersshanks
removed. (just turn the stack on its back and watch them swing).
I have had several instances of excessively tight pinning on these pianos.
Once repaired,( I repin them), the springs can be softened a great deal and
most of the "heaviness" is gone. This, of course, doesn't address erratic SW or
FW, but the correct friction makes a phenomenal improvement. It is also a
good time to do a regulation, since you will have a bit of spacing and traveling
to do.
Good luck,
