Graham Slee Elevator EXP Pre Amplifier

Graham Slee Elevator EXP Pre Amplifier 

The Elevator EXP Pre Preamplifier preamplifies the signal from a conventional output moving coil phono cartridge to moving magnet cartridge sensitivity. The signal is then fed to a moving magnet phono stage.

It's better than a step up transformer because noise cannot be induced into it, and it's far more linear making for a better bass response.

It's the electronic equivalent of a moving coil step up transformer, or as moving coil enthusiasts abbreviate it: SUT. However, a step up transformer easily picks up hum and electrical disturbances — it also consumes some of the delicate signal current to magnetize its core.
