That is the general understanding as well as my own. To my knowledge I've yet to see that confirmed or denied. The theory is that the different models sound different because of the differing densities of the bodies given the same innards.
Hmmm. Jade is the most dense of the stone bodies, I wonder what would happen if .........
Which would lead me to question when are they bringing out the ultimate body...a diamond body? Can we say 200 carats or more? Price...who cares, LOL.
The large pricing jump for the top Coralstone/Blue Lace seems to be mostly an artifact of the US distributors (perhaps to further inflate sense of "prestige"). Price differentials for the various stone models appears to be much reduced in Japan/Asia.
Was this mine Phil? I wish I didn't have to sell it at that time.
I listen in the market there are some seller that sell the Koetsu rebuild like new at one price list lower than normal seller
Will be true?
With all the e-commerce going now these days, we can never tell which is which. A rebuilt Koetsu is technically new inside except for the body. Mostly it is in the real net stores like Acoustic Sounds or Music Direct or Needle Doctor which will be more reliable, and provide warranties as sell.
