A lot of SUT's offer several settings, the Denon AU-320 has two, 3 ohm and 40 ohm. The Fidelity Research FRT-4 that Elliott just purchased has 4 settings so it covers a large range of carts.
A lot of hum and noise can be traced to poor planning, placing it next to an amp or other high power device along with running the cables close to power cables.Both Elliott and I were careful of our installation and are happy to report totally silent operation. A SUT that is set up carefully can be much quieter than an active phono stage. The quietest active MC phono stages usually cost big bucks as well.
