I completely and whole heartedly concur. Several years ago, I wanted a
newer player piano - after having an antique one, that then I knew very
little about and was getting too many leaks to pump.

I hated the way it sounded and sounded NOTHING like the antique one.

Now, not that I'm well versed in piano construction, but, to me, to get
the same tone - you would have to start all over.

- The wood the piano was built with is not the same - my antique player
is - all - walnut.

- The soundboard is most likely made of different wood.

- The plate is most likely not the same chemical makeup of iron.

Iron <http://en.wikipedia.org/wiki/Iron> (Fe) accounts for more than 95%
by weight (wt% <http://en.wikipedia.org/wiki/Wt%25>) of the alloy
material, while the main alloying elements are carbon
<http://en.wikipedia.org/wiki/Carbon> (C) and silicon
<http://en.wikipedia.org/wiki/Silicon> (Si).

- The strings - mine still has all its original steel strings - not
copper - again, the steel is probably not the same chemical makeup.

So, now to answer you question, you most likely are going to have to
checkout the kind of wood for the soundboard, the chemical makeup of the
plate and the chemical makeup of the steel strings.
