Choosing an SUT?


I'm shopping for an SUT, how do I choose one.  My cartridge is a Soundsmith Zephyr MIMC ES star lomc cartridge.

Compliance  10um/Mn
Voltage          0.4 mv

Any suggestions?

Call Bob Sattin at Bob's Devices for a Cinemag 1131 with switchable gain. Do you currently run the MC input on the Chinook?
Search around, there is an absolutely incredible number of different SUTs  out there to choose from. I do an awful lot of due diligence before buying anything. Many hours have been spent reading literally hundreds of pages on this one subject alone. There's websites of guys devoted to SUT who have tried dozens of these things. If you can find the right one, or maybe even if you can't, a SUT may be the most magical essential component ever made and will open doors unimagined in your musical experience. Or then again maybe it will just be a source of hum and noise and endless frustration. Which is why you don't see one in my system. But may also be why you will fall in love. I loathe pointless cliche'd writing but if ever there was a time to close with YMMV, this is it.
I just was on the soundsmith site where Peter Lederman recommends a transformer with a 1:10 ratio and >470 ohms.
To answer the question about using the mc input on my Chinook the, answer is yes. I am doing as much research about them as I can.  I want to experiment to see if I can improve the sound. 
When I spoke to Peter Lederman about the SoundSmith cartridges his recommendation was a minimum loading of 470 ohms and preferably less (higher number). I subsequently acquired one of Bob Sattin’s Sky10 SUT that has a 1:10 ratio setting with 470 ohms or a 1:5 ratio setting with 1880 ohms.  I don’t currently have a SoundSmith cartridge but employ the SUT with a Kiseki Purple Heart that has an output of 0.48mV and performs well on either setting into my MM (44db 47k ohm) input.
