What are Class D amps good for?
Modern Class D amplifiers are popular because they’re smaller, lighter, and run cooler than the other Classes of amplifiers with the same amount of power. These are big advantages when you have to fit an amp in a vehicle or carry one around for gigs.
Is class a better than Class B amplifier?
Class A amplifiers produce a very high gain. A 10 watt Class A amp will be louder than a 10 watt Class B. The Class A tube amplifies the whole signal, making it the cleanest and most accurate amplifier of all the classes.
Is a Class B amp good?
Class B amplifiers are much more efficient than Class A amps — 50% or so — but produce distortion as the two transistors switch on and off. This “crossover distortion” is so bad that very few if any manufacturers offer or produce an amplifier of pure Class B design.
