Ignore the troll, above. There is no single perfect cartridge, just as there is no best speaker or amp or whatever. The Cadenza Black is a great cartridge and I'm sure that you will enjoy it.
Similarly, Bob Sattin makes a great SUT. I'm not acquanted with anyone else who knows more about step-ups than does Bob. But... the Cadenza Black requires different loading than the other Cadenza models (10 Ohm), as does the Windfield, Anna and A90. I usually recommend pairing the Cadenza Black with the Ortofon St-80 SE SUT. If you already have the Bob's transformer, call Bob and ask if he can modify it for you. It will sound good either way but it will sound better with the loading optimized.
Good listening!
