The Elevator EXP is a separate unit flat response 22,5dB gain stage (having its own outboard power supply) optimised for MC cartridges, that will boost the signal to Moving Magnet level. Its distortion is near non-existent at less than 0.01% (including the test oscillator's 0.003% distortion). Rather than being designed for the convenience of the manufacturer, the Elevator EXP sports its cartridge loading switches on the front panel - for your convenience. Furthermore, we've included all the resistive loads you've been asking for. The Elevator EXP is supplied complete with a PSU1-24 power supply for the best possible performance.
