I actually would think one of the main reasons (beyond sound quality of course) for someone to buy a H-1200 would be specifically for the intended use with a ~0.2mV cart that wants to see roughly a 30ohm load. Other than the 38dB MM gain option there is no simple gain adjustability from what I've gleaned. Perhaps you could recognize some gain flexibility with the line stage you're using if desired. But at 0.2mV you should be all set...enjoy.
