Eminent Ex

The goal of every MC cartridge is to achieve the highest possible
output level with the lowest possible internal impedance.
Thanks to Mr. Matsudaira’s vast experience, My Sonic Lab
has introduced a cartridge that meets these criteria. The use of
neodymium magnets and a special material used to make the coil core
has resulted in an output of 0.4 mV at just 0.9 ohms. This is the Eminent Ex.
