I have not found the low impedance MI carts to be a good match with SUT's. While the reflected resistive load can be kept in line with what peter suggests, any capacitive load also quickly comes into play and causes a LC resonance with the cartridge inductance that quickly encroaches on the top end of the audio band.
the link below has a spice simulation of a 10Ω 2.75mHy MI cart into a 1:10 loaded with 47K. The plots show 100pf, 200pf and 300pf of capacitive load.
