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?!

Based on comments by Chakster, Dover, and Raul, this appears to be an obsolete unit, maybe sold in the 1980s, and very rare; the OP lives in Sweden. So you’d be very lucky to find one, let alone audition it. Raul suggests that the modern equivalent may be available from Etsuro.

I am in the market for a step up transformer.   This looks like a good one, anyone know where I can buy or audition one?

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.
