Reports are circulating out of the Koetsu Users Facebook group that Koetsu is no more. The family has decided not to sell to a third party to continue the brand.
I don't have a Koetsu, although I have considered one before. I have two Lyra Atlas Lambda (SL + Mono) and the builder is in his 70s, so that's always in the back of my mind for repairs/rebuilds. He does have an apprentice though.
