A Efficiency: Digital amplifiers achieve 85%-90% efficiency, while analog (Class AB) amplifiers only reach 30%-50%, making digital amplifiers more energy-efficient and eliminating the need for large heat sinks.
Sound Quality: Digital amplifiers can achieve high-fidelity sound through optimized circuit designs (e.g., pure direct mode), with some models supporting high-resolution audio like DSD 5.6MHz.
Size: Digital amplifiers are more compact, suitable for portable devices or dense installation environments.
