Normally you only need an RIAA preamp/filter for a moving magnet
cartrige. This curve is required becauuse the MM cartiige is
a velocity device, in other words, the highest signal occurs
at the zero crossing of the groove wiggle. The output is
usually only a few millivolts.
A ceramic cartrige is an amplitude sensitive device, and
would require a different type of compensation if any.
