MOSFET AUDIO AMPLIFIER(Low Noise and High Gain) : 6 …
https://www.instructables.com/MOSFET-AUDIO-AMPLIFIERLow-Noise-and-High-Gain/
Utilizing the high gain and high input impedance of short channel power MOSFETs, a simple circuit has been devised to provide sufficient drive for amplifiers upto 0.5 watt output. It offers performance which meets the criteria for high quality audio reproduction.

Mosfet amplifier topology without a driver can work very well for the application of class A with low output (let say 10watt) but will be felt weakness on the operation of large power and not a class A (class B).

Mosfet is a 3 terminal semiconductor device used in a wide range of electronic circuits. It works like a JFET but has less current leakage owing to an oxide insulation between the conductors. Mosfet is a good choice for building linear amplifiers owing to its lesser load, and any amplifier made using it is called a Mosfet amplifier.

Practical Mosfet Testing for Audio page 2 out the Drain. This connection has no current gain - the output current equals the input current. It can produce output voltage gain in phase with the input. The input impedance is the inverse of the transconductance of the Mosfet, and the output impedance is the value of the Drain resistor.

Mosfets for improved hi-fi audio design Steve Bush. It is not difficult to design any old audio amplifier, but it is tough to design a good one. Two recently introduced Mosfet pairs may help by taking some of the fuss out of audio power amp design. Japanese component maker Sanken has introduced matched N and P-channel Mosfets specifically aimed ...

Hi, I want to know what is the selection of high power mosfet (N channel) for audio amplifier purpose. Currently I use 2sk 3911 (Toshiba), seems it has high spec (600V, 20A), but very high input capacitance (around 4nF). Considering another kind of MOSFET to get more clear, nice sound of my...

Project 101 - High Fidelity Lateral MOSFET power amplifier
https://sound-au.com/project101.htm
Lateral MOSFETs are designed specifically for audio, and are far more linear than the (currently) more common switching devices that many MOSFET amps use. Unfortunately, they are not especially cheap, but their performance in an audio circuit is so much better than vertical MOSFETs, HEXFETs, etc., that there is no comparison.
