Ultra low distortion composite amplifier kits TDA7293 TDA794
https://www.kaltecs.com/tda7293-composite-amplifier/
I hoped to achieve the ultra low distortion and noise of the LM1875 composite. After some ups and downs I managed to build a TDA7293 or TDA7294 composite amplifier achieving the perfect sound of LM1875 but capable of providing a lot more power. The TDA7293 TDA7294 ICs use a MOSFET power stage, whereas LM1875 uses bipolar transistors.
A LOW-DISTORTION CLASS-AB AUDIO AMPLIFIER WITH …

tures of audio ampli ers are low power dissipation, high output power and low distortion[1],[2],[5],[6],[7]. The ideal choice for audio ampli ers are class-AB and class-D ampli ers [6]. Though class-D ampli ers have high e ciency, low power dissipation and low distortion [5], class-AB ampli ers are preferred for designing
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.
Ultralow Distortion Audio Panpot Amplifier | Analog Devices
https://www.analog.com/en/analog-dialogue/articles/ultralow-distortion-panpot-amplifier.html
The AD8273 1 dual low-distortion difference amplifier uses internal gain setting resistors to ensure excellent matching between the two channels. With no external components, each channel is configured as two high-performance amplifiers with a gain of 3. In the audio frequency range, the total harmonic distortion is less than 0.0007%.
Ultra-low Distortion Class-A Amplifier
https://www.sound-au.com/tcaas/nj10w.pdf
Ultra-low Distortion Class-A Amplifier A design using feedback to control the gain and the levels of voltage and current in the output stage By L. Nelson-Jones, M.I.E.R.E. There is in the design to be described nothing very revolutionary, but rather an attempt to get a little nearer to perfection, in the power amplifier section of an audio system.

Some more info you can find here - Low Distortion Audiophile Amplifier Kits LM1875 TDA7293 and any descent textbook. The circuit is shown on fig 1. The input impedance of the amp is determined by R1, which in this case is 5.1K and a good compromise.
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 …
DISTORTION MEASUREMENT IN AUDIO AMPLIFIERS
https://renardson-audio.com/distortiontest.pdf
A low distortion sine wave is applied to the input of the amplifier being tested and the output fed to the input of the notch filter, which is adjusted to eliminate the frequency of the test signal. The remaining signal contains distortion and noise from the amplifier and can be measured on a r.m.s. meter to give a percentage t.h.d.
Ultra Low Distortion Audio Composite Amplifier Kit LM1875
https://www.kaltecs.com/lm1875-composite-amplifier/
Ultra Low Distortion Composite amplifiers based on LM1875. LM1875 is a little nice chip amp capable of providing 25W output power. If properly implemented it provides surprisingly good sound. The simplicity of the circuit and its sound quality have ranked that IC chip among the most popular among DIY enthusiasts.
