Excel Sound Corp ST 1 step up transformer

Hello!
Anyone here with any information on this step up? The exakt description is;

Excel sound corporation Super ST 1 MC transformer

I am now playing it on my Kuzma Reference 2, 4-point 11,5 inch arm, My Sonic lab excellence ex and an excellent swedish phonoamp Simply Black phono and its sounds so good! I have asked the manufakturer in Japan about specification but they have none?!

Dear @persve : Maybe your SUT is even better to this one that Excel design and manufacture for Etsuro and that's very expensive unit:

So, congratulations for the unit you own.

Regards and enjoy the MUSIC NOT DISTORTIONS,
