Capacitance is not an issue for MC cartridges; only for MM. Best to set it as low as possible for other reasons. For impedance, the mfr's recommendation was 100 ohms, but many of the reviewers liked 1000 ohms or even 47K ohm. After you set the tracking angle and tracking force, try all three. The one that gives you the most realistic soundstage with good dynamics is the way to go. If the highs ever get in your face, then set the impedance lower. NEVER run the cartrige below 1.5 gram tracking force.
Best of luck,
