Choosing the right SUT for my setup



I’ve decided to add a SUT to my setup. My MC carts are a Denon 103R (14 ohms/0.25mV) and an Audio Technica AT-OC9XSL (12 ohms/.4mV). I’m trying to decide between two used SUTs: the Denon AU-300LC and the Denon AU-320, both having a 1:10 ratio. Would loading ideal gain for the 103R and the OC9 be best achieved thru a using a calculator and installing a resistor that can be switched for carts or testing with a trimpot then installing resistor? I’ve also seen writeups where the OC9 is put on a 1:12 SUT and 1:20 for the 103R; from the boards experience is that pushing overload, or its in a good spot?

Thanks for all the advice to everyone who posted. One SUT for both carts. So I've make a decision between a used Ortonfon Vero, and two DIY kits for the Cinemag 1254 and the Sowter 1480 or 9570. I've built my own preamp from plans, so I'm no stranger to DIY. The question now is who builds a qualty kit? I found this one on ebay but I question its quality. Can't find anything on the brand name 'Mazur'. Any names for a decent chassis kit would be greatly apprciated. 

 

What about a premade SUT by Jensen? The JT-34K-DX model# MC-2RR-H ISO-MAX series. The specs look good. Has anyone given this a listen?
