Better Class AB amplifier designs slightly outperformed the current dumping designs. The Leach amp by Marshall Leach is a good example. Of course once Class D amplifiers started becoming good ...

The result is an unusual amplifier, brought back to life. You may have seen [Jane] feature here before, with her 1950s signal generator . Continue reading “Bringing A Current Dumping Amplifier ...

With signature FiiO power, innovative engineering and sleek aesthetic sensibility, the K15 is a full-system desktop DAC/amp ...

Coming from Yamaha, a standout brand for soundbars, the A-S301 is a Class AB amp with some strong stats behind it.With a signal-to-noise ratio of 99 dB, compatibility with a range of speakers ...

He said Class AB amps typically run at between 15 and 40 percent efficiency when playing back music, while Class D amps run at between 40 and 85 percent. And that's only part of the picture.

In a Class A circuit the level of that current is always set to maximum. If that amplifier design is working at full volume then the bulk of that energy is used to drive the speakers. (Note that no ...

A Class D amplifier provides better efficiency and thermal performance than a comparable Class AB amplifier, but implementing a Class D amplifier still requires attention to good electrical- and ...

Class AB amps, like the A-S301, depend on two transistors that are on most of the time. Crossover distortion is mitigated with an efficiency of approximately 60%.
