Class B amplifiers are more efficient than Class A amplifiers but can introduce distortion at low signal levels due to crossover distortion. Class D amplifiers, on the other hand, are highly efficient and convert signals using pulse-width modulation, making them well-suited for portable and high-power applications, though they may introduce switching noise. The choice between them depends on the specific requirements for efficiency, sound quality, and application.
