Don't know if this helps, as I had the Sugano son Goldline, not the Sugano San one advertised (eff. the same, though) and it was exc. on my SME Five (11g eff. mass; at the lowest end of the medium mass arm range). Obv., being a K, it'll prefer a heavier arm. I loved its full-blooded dynamism after my Lyra Helikon and was, for a time, slightly disappointed in its replacement, the Urushi Vermillion with a much lover output.
