Seldom mentioned is the Jensen SUT. The mc-2rr-L @about $600 is a very good one. This version is a 1/10 ratio with an impedance of 430 ohms, which is what the cartridge will see. It is a great SUT for both the Hana el/sl or the denon 103. It is made in the USA. It is available in a 1/20 ratio as well.
