  Class AB vs Class D Amplifier — Ultimate Comparison (2026 Guide) In the world of audio amplification, Class AB and Class D are two of the most common technologies powering everything from hi-fi home systems to compact portable speakers. Choosing the right type can make a big difference in performance, efficiency, and sound quality — especially for audiophiles and gear builders. 📌 What Are Class AB Amplifiers? Class AB amplifiers are a hybrid design that blends elements of Class A and Class B, producing a smoother and more linear output signal. Unlike pure Class A amplifiers, they bias their output devices just enough so both halves of the waveform overlap slightly, reducing distortion. Key Features: 🎶 Low to moderate distortion — ideal for detailed, natural sound. 🔥 Moderate efficiency (~50–78%) — more heat produced, requiring larger heat sinks. 📦 Larger size than Class D due to thermal management needs. 🎛️ Frequently used in hi-fi systems, professiona...
