First the basics: What does an amplifier do, and do you really need one? In a nutshell, a stereo amplifier receives a low voltage signal from the source equipment — a CD player, Blu-ray DVD player or turntable, for instance — and enlarges or amplifies it, sending the signal on its way to powering your speakers. The functions of an audio amplifier can be split into two sectors or components.
