I have attempted to line up each of the Koetsu names (i.e., stones) of the stone body cartridges against the MOH list of stones, but, based on the subjective comments I have read about the sonic characteristic of the stone body cartridges, there does not seem to be a consistent, linear relationship between MOH number and sound (i.e., the harder stone bodies being progressively more detail-oriented and analytical as you go up the MOH scale, and the softer stone bodies progressively having a warmer total balance as you go down the MOH scale).
The different pricing for different stone body cartridges where there is little agreement on the sonic characteristics of the cartridges makes the Koetsu stone body line of cartridges a confusing morass. Is there any way to rationalize the Koetsu stone body line-up (or not because different people will hear different things from each model of cartridge)?
