Indeed and it says 0,4 for the sky blue .
The vermillion red specs from the needle doctor are contradictive , in the specs it says 0,2 and next to the picture it says :
The red-lacquered Urushi Vermillion uses a low-capacitance cantilever wand a Quadrahedron stylus. Its samarium-cobalt magnet and silver-clad six-nines copper coils produce an output of 0.4mV. Though it was "slightly polite on top" and lacked some air and space it's "rich and colorful" sound was never soggy or too romantic. The "artfully coded" Vermillion proved to be "one of a handful of most muscly engaging cartridges" in MF's experience.
If MF is michael fremer you now whom i trust , i ll check stereophile on the review .
I also asked another " well informed" source .
