It's been an interesting thread so far, I used an Ortofon SPU with a transformer built into the headshell and from that into the mm section of my pre-amp so I guess from what Barry said, that is a SUT.

So is the Albarry MCA11 I use a head amp or a phono stage? does the fact it is battery powered mean it is active? It is switchable to 25.50 and 100 Ohms.

I'm not good with electrickery, but to be fair the MCA11 has lifted my system to a new level.
