Cartridge Impedance


I just bought a phono pre-amp that allows me to adjust the impedance of a MC cartridge. I was using 100ohms. Now I want to experiment.
Could someone tell me the effect the trebles will have if I lower or raise the suggested impedance. For example, If I raise the impedance will the highs be more prominent or less prominent? 
Thank you.

@lewm   Nice summary.

@rauliruegas   Not true. My Koetsu (LOMC) responds to load resistance, but not load capacitance. I usually run it at 1K or more, with internal resistance at 5R.
@rauliruegas

The OP is talking about loading his cartridge at his phono stage. When you post, "LOMC cartridges are not sensitive to load impedance, are sensitive to inductance changes," you imply that impedance does not affect the sound. That is incorrect.

Perhaps you meant to say, "It is the preamp, not the cartridge which is sensitive to impedance." That statement would be true, but irrelevant, as the OP wants to know how to set up his system. Compare your statements to those of Lewm and Atmasphere, who contribute to the discussion by explaining the technical details as well as addressing the OP’s point.
