For a moving coil cartridge with 0.4 mV of output, you probably need a phono preamp with about 60 db of gain (as already suggested). However, that depends a bit on whether you have a solid state or tube preamp. Generally speaking, a solid state unit with a bit less gain (say 50-55 db) may still work OK because it is usually quieter than a comparable tube preamp.

In a recent thread recommendations were solicited for possible MC cartridges for a Phono amp with 20db of gain. The cartridge I offered has an output of .4mV. Several replys indicated the two would not work very well because of insufficient gain. Is there any simple rule of thumb or explaination of the gain to output relationship?
