Q3 is directly driving the final amplifier MOSFETs (K1058 & J162), which can produce up to 100W RMS power output (theoritically), which can not be applied at the BJT end amplifier (because the BJT is ‘current operated devices’ while the Power MOSFET is ‘voltage operated devices’ which does not require large currents to drive it).

vertical power mosfets (and similar technologies, such as pi and trench types like toshiba j200/k1530) tend to have a 'sweet spot' where the capacitance, gm and current are sensible enough tp get good performance in audio - usually this happens in mosfets with vdsmax between 100 and 300v - usually on the lower end of this range for p channel …

The shown MOSFET amplifier design circuit will happily output a 35 watts RMS into an 8 ohm load. The total harmonic distortion will not be more than around 0.05%. The prototype was analyzed only for signal frequencies around 1 kHz. However the circuit's open loop gain was found to be practically constant within the entire audio frequency range.

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 ...

Short term (or 'music') power is typically about 240W into 8 ohms and 380W into 4 ohms. Note that depends to a very great degree on the power supply, and a robust supply is a requirement for the maximum output. The recommended supply voltage is ±56V.
