Keith Herron is a proponent of "infinite" loading of mc cartridges. Gauging by atmasphere’s excellent post above, one can conclude Herron pre’s are also stable designs. Loading of mm and mi cartridges is a different matter.
input impedance load on a cartridge.
I am interested in purchasing an MC cartridge that prefers a 400ohm "load"from the pre amp. My head amp for MC cartridges provides 110ohms which is the highest recommendation for the unit (according to the manual). In theory I should be able to change the resistors to alter the load but I am worried that going beyond the recommended value would harm the pre amp/head amp.
Can I alter the resistors to accommodate the cartridge or should I be looking for a different cartridge (or a different head amp)?
I am particularly interested in the possibility of changing the load. The alternative cart/pre option is of secondary interest.
