Alongside the AV preamp or stereo preamp, an amplifier is the second piece of a separates-based audio system—it provides the power for your speakers.
Going the separates route is generally considered to be the higher-performance option, as opposed to using an all-in-one AV receiver, because the manufacturer can focus more on selecting just the right components and design elements for that device’s specific function. And you can focus on choosing the right amplifier technology (Class A, Class AB, Class D, etc.) and configuration (mono, stereo, five-channel, etc.) for your needs.
