Dynavector Cartridge Load 100ohms or 47k ohms?

The higher the input resistance, the lower the damping factor is going to be and the more likely it will be that your MC cart. will have a rising high end and experience ringing. The lower the resistance, the greater the damping. See Bob Hagerman's excellent discusion of cart. loading on his web site. Generally MCs will prefer a lower load with a SUT than with a head amp or gain stage. I think this is because the lower load enhances the current output of the cart. and a transformer is a device that converts current into voltage. Whereas a head amp is looking for voltage and will do better at a little higher loading. For a short while I had thought that my Sheltor sounded better at a higher load; until a singer hit a note that almost drove me out of the room. A lower load brought things under control.

One way to do this is to lower the loading resistance until the soundstage collaps. Then go with twice that resistance. In my case with a Shelter 90X that happened at 20ohms. 40ohms sounds about right. 100ohms a little too bright.
