Choosing an SUT?

http://www.rothwellaudioproducts.co.uk/html/mc_step-up_transformers_explai.htmLots of good information here to explain how to match a cartridge to a SUT and match it to your phono stage.

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.

Why do you need a SUT for 0.4 mV cartridge ? 

Hi,

i can understand it if you want to avoid the JFETS in MC input, that may give better sound but a gain of 60db should be more than enough.
