After recently modifying my Rotel Phono amp it now has (or should have ) the following specs for the cartridge inputs: Sensitivity MM 3.0 mV Overload: 110mV Sensitivity MC 0.27mV Overload: 10 mV If I where to replace my current cartridge i would probably try another MC cart. Am i right in thinking that i could choose any MC cart and use it on the MC input of my amp as long as the cartridge output is between 0.27 mV and 10 mV.
