I didn't see your comment that the piano is less than two years old.
Though that doesn't change my view of some of the problems, it does
change how you can realistically address them and I would opt for string
seating, making sure the hammers are hard enough underneath and aren't
mushing out in the upper area of the piano, hammer shape and fitting.
For focus I think you need a pretty firm supporting structure of the
hammer that is not too hard on the crown-iron fist in a velvet glove.
If you have an iron glove in a velvet fist, achieving power by a few
drops of hardener on the surface without the support underneath, then
when you play the piano loud the hammer will collapse and you'll lose
focus.  That's my opinion anyway.  
 
The mild knocking sound can often be the cushion on the jack hitting the
spoon, as someone mentioned.  If you release the key slowly,  you should
be able to hear it when the jack releases off the knuckle.  It might
simply be more audible when the una corda is on because the piano is
quieter.  One problem is that the D hammer is pretty heavy and there
needs to be a lot of tension in the spring, so when the jack releases it
can slap pretty hard on the spoon.  Changing the button will probably
help though, at least for awhile.

Two problems with the D. (Yes the same one)
 
First, I misinterpreted the faculty's comments. It wasn't "brassy" as
such, as much as it lacked focus. I perceived this to mean to bright. So
I voiced it down. But now he says it has lost it's power. He says the
hammers will never come back. Is he right, or is there a way to get the
power back on without them becoming too brassy?
 
The other problem, which I also misunderstood, is a noisy action. He
said something about it when he complained about uneven voicing with the
soft pedal on, but I missed his comments. I compared the action noise
with that of the other D, and there does seem to be a little more action
noise. I've narrowed it down to when the hammer returns, kind a of a
mild knocking sound. I tried voicing up the wippen cushion, but that
didn't do anything. Could it be that the back under key felt is too
hard? Would that solve the noisy action? (remember, this piano is less
than 2 years old.
