Yamamoto YC-03s cartridge - hardly recommended

Japanese make some fantastic cartridges but some are very popular and some are not. Yamamoto has been mostly been working on tubes and analog equipments and they have only one cartridge. However it doesnt seem to be very popular among audiophiles here. I dont see it being recommended or discussed. The price is very competitive at just over $1k. There is only one review on the internet. Has anyone heard it ? Is it worth giving a try ? Looking for some opinions here.
No one has even heard it ?
I have the mono version and think it's very lively and dynamic!
