Some of the high-output MC cartridges designed for 47k Ohm are exceptions to the general tendency for MC cartridges to be for practical purposes immune to capacitance changes. Sumiko's manual for the Blue Point No.2 says this:


If your receiver or pre-amp has capacitance loading capabilities, a Sumiko high output moving coil cartridge should be loaded with a value no higher than 200pf, and ideally below 100pf.
