What does a Preamp and Power Amp do for my stereo system?

People often call the Preamplifier a Preamp. They often refer to the Power Amplifier as a Power Amp.

John says the Preamp acts as the control device. Everything plugs into it. It contorls the volume, the EQ parameters, the tone and many other aspects of how your audio will sound.

The Power Amp acts as the motor. The Preamp sends it a signal, and the Power Amp makes the signal bigger. The signal needs to have enough power to reach all of your speakers at whatever volume you choose.

So if you view it as a vehicle, the Preamp provides all of the controls and Power Amp would act as the motor.
