  I have my own restored S&S D in the shop right now.  On of the problems 
with any piano with a lively board is making it shut off especially big ones. 
It's possible this piano has no damper return springs or if so they're not set 
strong enough especially in the bass. The lowest bichord unison especially wants 
to sing on this piano & I had to increase the spring tension. Also 
insufficient string braid in the lowest tenor section with the long segments will sing 
like a soprano if not done correctly. Also do a staccato check on each note 
without pedal & if shutoff isn't quick then usually one string is not being 
damped because of uneven damper or string/agraffe spacing. Slit the trichord & 
apply kite string in the groove. Sometimes the string can be moved sideways ever 
so slightly in the agraffe with a screwdriver to even the spacing.
  Also check for the duplexes singing right above the bass strut. I had to 
braid a few here as well. 
    With My D piano I think I also here the tuned duplexes singing quite 
strongly especially in my shop. My acoustics are ... poor but It was rented for 
the Joshua Bell Symphony Concert this weekend & in the hall it was not a 
distraction but part of the acoustic content.

While were on this subject, please allow me to change pianos. Last year I 
brought up the problem of a student complaining about a B having too much after 
ring. Now one of the piano professors said the new D has too much. I thought it 
was the "nature of the beast," but the piano professor claim earlier 
Steinways do not have this problem. He claims another piano technician, well known to 
this list, at another SEC school, said it has something to do with the alloy 
in the damper wire, or something to that effect. (If you know who you are, you 
may identify yourself.) 

What is the opinion on this? What, if anything, have any of you done to solve 
this problem?
