Hi there Del Now this is an angle I must admit has never crossed my mind, and an interesting one to be sure. And its just the kind of thing I like to think about as well... sort of philological if you will :) I am not really sure how to approach an answer either, outside of saying that I suppose much would depend on just how conscious S&S are of the changes a compression crowned panel goes over time. To date I have yet to see them responde to any of the criticisms and concerns raised by you and others, in any sort of justification for why they do what they do. I did hear a newly employed C&D tech in New York (at the Reno Convention) say that they have their reasons for the things they do, but just dont want to get into any arguements about them. Seemed like a weak avoidance to me, but then I am in no position to demand answers from them to be sure. So when does a Steinway cease to be a Steinway on its own.. without any exploratory or otherwise surgery as it were ??? Good question Del.
