Class D Audio Amplifiers: What, Why, and How | Analog …
https://www.analog.com/en/analog-dialogue/articles/class-d-audio-amplifiers.html
The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion. Audio frequencies range from about 20 Hz to 20 kHz, so the amplifier must have good frequency response over this range (less when driving a band-limit…

Apollon Audio Hypex Based Class D Handbuilt Amplifiers
https://www.apollonaudio.com/
Apollon audio amplifiers that are based on the Hypex NC1200 Class D modules use a custom built buffer board on the input stage. The buffer board is using only the highest quality 1% metal film resistors and true audiophile grade polystyrene capacitors while the power for the Op Amp is regulated with discrete voltage regulators.

On the whole, Class D Amplifiers not only deliver high-quality sound but are also very energy efficient. The Bad. In the past, Class D Amplifiers produced a hard flat sound. The clarity of the sound is slightly less crisp than the larger amplifiers, but not enough for a “lay person” to discern a large difference.

While all the amplifier classes previously mentioned have one or more output devices active all the time, even when the amplifier is effectively idle, Class D amplifiers rapidly switch the output devices between the off and on state; as an example, Class T designs, which are an implementation of Class D designed by Tripath as opposed to a formal class, utilize …
