The simplest preamplifier is the passive level control, whose only function is to attenuate the input signal of any component that provides line level output, before it is fed to the power amplifier. Passive level controls are preferred by audiophiles because the only electronic component between the source signal and the power amplifier is a variable potentiometer or a stepped resistor. This results in sonically superior performance, but on the down side it is the output circuits of the components that must carry the burden of driving the power amplifier. All other preamplifiers buffer the components from the power amp and assume the burden of driving the input stages of the amplifier.
