Piano plate casting founderies are unlikely going to change their
casting equipment.  The kind of tolerances required by a piano plate
are so high and the profit from each one so narrow there is no
incentive to do so.

I do not know that soft plates are inherently superior to a harder
plate.  Parts of plates do resonate, old ones and new ones alike.  No
challange there.

What I do challange is that one plate of one make cannot be compared
to another plate by a different make because all design parameters are
not the same.  Make two castings from the same foundry, one hard, one
soft, is the only way to amke a valid comparison.  A design difference
is more likely a source than the metal.

Ed is erudite and knowledgable, no question there.
