Exactly, agree on all points, and I especially like the observation that wir=
e=20
is not perfectly elastic, and of course simultaneous unison strike is=20
paramount considering the jarring clang if not, so-......   the gentle curve=
 to=20
termination takes away no sound quality from the string ? This is my primary=

question. Some techs attribute a better sound as the piano ages away this cu=

not sure. What about that ?
