Quad had something similar with their earlier pre amps, with removable input boards for cartridges, and tailored boards for many well known cartridges of the day. The tape input board had adjustable settings for sensitivity, and I still use that to avoid clipping on the input by my Chromecast Audio. Peter Walker was a very practical designer.

Curious to know why some audiophiles prefer a moving coil cartridge over moving magnet type. What determines this preference? Does the tonearm determine which type is preferred? Why?
