Any Members Tried the Audio Interface CST-80 SUT?


My curiosity got the better of me and I just bought this SUT from Japan and wondered if anyone else had any experience with it. The very little I could find seemed to indicate it is a respectable unit and has even been likened to the highly acclaimed Cotter SUT.

It was made in the US around 1982 and came in two varieties. There was a 3 Ohm version with 30dB of gain and a 40 Ohm version with 20dB of gain.

I currently use a Fidelity Research FRT-4 which is excellent and has 4 different taps 100 Ohms, 30 Ohms, 10 Ohms and 3 Ohms + Pass Through for MM.  It will be interesting to see how it compares the FRT-4.

I will use it with my 1.0 mV / 60 Ohms Shinon Boron Red which currently uses the 100 Ohm tap on my FRT-4.

Coming in late here, but, a friend gave me one of the 3 ohm versions to sell for him along with several other pieces. I don't need it for my own system as I added Sowter SUTs into my Hagerman Trumpet years ago. I'm trying to get a sense of the value of this. Thoughts?
I notice there is one for sale in Japan for $900 but it has obviously gone unsold for quite some time. That kind of brackets the price effectively. I wish I had a use for it but I look forward to finding an appropriate home soon. Thanks again!
