GoKawiilExplainer: How amplifiers boost and shape audio in home sound systems
A technical explainer breaks down why raw audio signals, like a turntable's faint needle vibrations, need amplification to become audible, and clarifies the amp's role in boosting gain and shaping sound via equalization. It also distinguishes amps from preamps and notes that many consumer speakers already have built-in amplification, so a separate amp isn't always necessary.
