I've settled at under 100ohms for a load. This cartridge has a very low internal resistance of 5ohms. Applying the typical multiplication factor of 2-10x internal resistance leaves a value far below 100ohms. I preferred 50 ohms but 30-50 would work for my ears. These settings also made sense when I measured the frequency response of the cartridge using a Cardas test record.
