What are class AB amplifiers used for?

Then the basic purpose of a Class AB amplifier is to preserve the basic Class B configuration while at the same time improving its linearity by biasing each switching transistor slightly above threshold.

What are Class D amplifiers used for?

Class-D power amplifiers are available that are rated at 1500 W per channel, yet weigh only 21 kg (46 lb). Radio frequency amplifiers may use Class D or other switch-mode classes to provide high efficiency RF power amplification in communications systems.

Is a class AB amp better than a Class D?

Class A design is the least efficient but has the highest sound fidelity. Class B design is a little more efficient, but full of distortion. Class AB design offers power efficiency and good sound. Class D design has the highest efficiency but isn’t quite as high-fidelity.

Are Class D amps any good?

Even so, the efficiency of a practical Class-D amplifier can be better than 90 percent, which is significantly better than a Class-AB design (78.5 percent at best and typically closer to 50 percent).
