Yamamoto Acoustic Craft's monaural step-up transformer SUT-02 is for low-impedance MC cartridges.
I'm embarrassed to say that I didn't know about the existence of the high-impedance version of the SUT-03 until relatively recently.
The SUT-03 has the same excellent performance as the SUT-02.
The impedance of the cartridge conforming to SUT-03 is 5~40Ω, and its amplification factor is designed to be 10 times.
Please give it a try.
