Dear Yewhlock: You already has the cartridge manufacturer advise so you only have to try different impedance values and choose the one that works better in your system the one that likes you more.

You can start with 840 Ohms and try 100 and 5100 and see what happen what you like it. There are not a precise rules about other that test different values.

In the other side what for other people works maybe does not/can't works with you due that your system is different.

Regards and enjoy the music,
