Be aware that most RCA plugs have anywhere from 18 to 30 pF of capacitance or more, all by themsleves. DIN plugs to plug into tonearms can also have a signficant amount of capacitance, and the RCA input jack will also have about 1/2 to 2/3 the capacitance of an RCA plug.
Minimize the effect of the capacitive loading on an MM by using slightly lower load R than nominal, instead of 47 kohms, try 33 kohms, this will tend to damp the HF peaking and make the capacitance value less critical. It might make some MM cartidges sound a bit 'soft' in the HF's, but if you listen for awhile, you will find it is a more natural HF.
