Cartridge MC matching with phono Cary audio PH303

Thanks, but I am not full understanding what you recommended since I am newbie on this .
What mean without loading?

Don't use a 100 ohm resistor or the like. The input of the phono section is 47K so it should be just plug and play.

My phono preamplier is Cary Audio PH302

- GAIN MM: 38 DB (2.0 MV MINIMUM)
             MC: 54 DB (.15 MV MINIMUM)

- INPUT IMPEDANCE:
    MM: 47 K OHM
    MC: 100 OHM

Can't adjust,  plug & play only.

The question the cartridge  AT ART9, is it matching with this phono?

Thanks,
Dong.

It should work. Put it into the MC input.
