No, I never said Sugano was physically or manually producing each cartridge. It is unthinkable at such age. My point was that Fumihiko was trained personally by his late father Yoshiaki, but Fumihiko never trained a son, from my reliable source. There are more personal details which I chose not to mention publicly as it was from a private chat. The old man , and his late father, never even provided any technical paper, even a tiny one, to show specs, graphs, measurements, etc. This method alone is the mystical one considering its high price. No tools, no decor, not much markings but just a box with it's logo. So I base my opinion of what we do not know about the technical methods. The next group will have to follow or not, I do not know. Do I believe Fumihiko sat down to listen to all the stones he chose ? Yes, because I was told so by my source. And Fumihiko not too long ago had rejected a special request to make a Granite version. Why ? Obviously because he didn't like the sound and it would make a 'bad' representation of his brand name. There was already a member here, who made a qualification, or a short review of about 4 different stones, and he made some distinction of 1 over the other. I know him very well. If the magic of its sound lay somewhere else like the materials and weaving etc done with it, it would have been easy for other cartridge makers to repair or rebuilt the cart, and if that is the case, nobody would have wanted to pay $3,000 or more to have Koetsu do it. The 'others' will just have a booming business on this facet alone. My points have exactly been made to honor the legend, by stating that there will be some difficulties to be encountered in continuing this legacy with an 'outside party or parites'. If another clan comes in and maintain pound for pound of the Koetsu sound, that would be the best. But how easy can that be? That's what is on my mind. Many people have told me they believe the next group would not be able to make the sound the same, but there is always a possibility that it can. And for the sake of keeping that name, legacy and legendary status, I am all for it. Why not?
