Author: Pablo Manuel Delgado et al. The main objective of this project was to get familiarized with the aspects of constraints, design, simulation and implementation of a discrete component low distortion professional audio power amplifier, from scratch. This took place within the course of Analog Circuit Design at the University of Buenos Aires. The total time …
4QD-TEC: Low distortion Audio amplifier
https://www.4qdtec.com/pwramp.html
Low distortion audio amplifier This is an unusual circuit for an ultra-low distortion power amp. According to my original notes the circuit is dated January 1977 so the circuit is not exactly modern but it is still sufficiently different to be interesting.
Ultra low distortion composite amplifier kits TDA7293 TDA794
https://www.kaltecs.com/tda7293-composite-amplifier/
Both amplifiers have similar very low THD and noise. At very low power (0.5 – 1.0W) it is really difficult to find any difference. Increasing the output power (5-10W) however makes some sight differences visible (hearable). Blind tests pushed the scale a little bit in favor of TDA7293 composite but not in all genres of music.

A high efficiency and low distortion and switching power amplifier is proposed. We use feedback to reduce the total harmonic distortion (THD) and the DC output bias current. The experimental results show that the proposed circuit has 0.24% total harmonic distortion and 91% power efficiency while the DC output bias current is 12 μA at 1.5 V supply voltage.
The AHB2 - A Radical Approach to Audio Power …
https://benchmarkmedia.com/blogs/application_notes/14680625-the-ahb2-a-radical-approach-to-audio-power-amplification
The switching supply in the AHB2 responds to bass frequencies, maintains a constant low-ripple output voltage, and delivers very predictable output power. Low Stored Energy - Most audio power amplifiers rely on a bank of large capacitors for energy storage. These capacitors remove some of the ripple produced by an unregulated linear supply, and help …
Ultra Low Distortion Class B Amplifier - diyAudio
https://www.diyaudio.com/archive/blogs/comments/comment2715.html
This is a Class B power amplifier that follows the Ultra-LD Mk.3 amplifier design published by the Australian Silicon Chip magazine in 2011, which in turn draws heavily from the concept of a Blameless amplifier devised by Douglas Self. I used a different power supply and speaker protection, and changed the grounding scheme vs what was published. The distortion …
