What is the lower limits to human sensitivity, especially when a cartridge, phono section, and preamp will further amplify any magnetic changes (via EMI inductance). Since a typical MC cartridge has a mere 3 millivolt output and that has to be amplified to about 2 volts at the preamp outs, please elucidate what the lower limits of human sensitivity is, especially in consideration that the lower dynamic range of an LP would be significantly lower than 3 millivolts, at least by 40 to 45 dB for a typical LP.
