SUT Opinions

Looking for SPU users experience with SUT.
I have recently acquired an SPU Royal G Mkii and before I spend $$$ want to get an idea on what SPU owners are using.

System is as follows:
Miyajima EC-5 Preamp
Thorens TD-124 Mkii fully updated
Ortofon RMG 309i tonearm
Ortofon TA-210 tonearm
SME 10 Turntable w/SME 10 Tonearm 
Pass Labs X-260.8 Amplifiers
Esoteric N-05 Streamer(Dac not used)
Ypsilon Dac-100
True Sound Works Apogee Duetta
Shunyata Denali T
Audience AU24 se speaker and interconnects
Shunyata Alpha and Cardas Golden Reference power cables
Billy Bags Pro Series rack

What about GAIN on your Miyajima Preamp , there are 3 phono inputs as I can see.

"The right photograph is a changeover switch of the input impedance of B and C.

B : 600~47kΩ
C : 600~100kΩ

An impedance matching improves by matching the impedance of the pre-amp to the impedance of a cartridge and the step-up transformer. When impedance is unclear, please choose 47kΩ."
There is 38db from the mm phono pre in the EC-5.

Given that you have a Miyajima preamp you should consider this. I have one and you can accommodate a wide range of cartridges including your SPU.

Dear @cfarrow  : Why do you think or want a SUT? Do you already test the SPU in your EC-5?

Regards and enjoy the MUSIC NOT DISTORTIONS,
