Ahh amplifiers. Start with the best open loop amp you can make, then apply some feedback. Not a lot.. Excessive feedback only introduces phase problems and poor design. Waveforms are rarely sinusoidal, loads are vaguely resistive. Design for good open loop step response low output impedance and good frequency linearity. Class a is good if your room needs heating, but b can work quite well.
Spent years trying to convince punters at Earls court, Harrogate and many other venues, the musicality of designs capable of sourcing huge amounts of open loop current.
