Techdas TDC 01 cartridges

The two Techdas cartridges TDC 01 and the Ti version have been out for a while now. Has anyone heard one in their system and if so what do you think?
They're basically the same cartridge with minor sonic differences and
among the very best of today. Same level as Ortofon's McAnna, very
natural and musical; the best compliment I can give any piece of audio
