The job of a preamplifier is to turn a low-voltage, high-impedance signal susceptible to signal degradation, into a higher-voltage, low-impedance signal. This process is often referred to as adding gain, and preamplifier specifications often refer to how much gain the preamp provides without introducing audible noise. The output of the preamplifier can then be safely sent along to a power amplifier that will raise the current to levels that can drive speakers.
