Simple voltage amplifier stage followed by power stage, and a bootstrap cap. It increases almost by a factor of 2 the overall gain. But simulation with Spice also shows an increase of distorsion THD-1 and THD-20.

for me VAS is the short form of Voltage Adaptation Stage. Amplification is not its job.

For Bob Cordell (Audio Engineer, great expert of Audio Amplification) VAS is Voltage Amplifier Stage.
