OPA541AP is an 11-pin power op amp.
It can deliver Peak 10 Ampere and have +/-40 Volt supply.
This circuit can output more than 100 Watt into 4 Ohm and like 55 Watt into 8 Ohm.
Supply is +/-35 Volt DC and the transformer should be 2x25VAC.
At the image is an output of 100 Watt into 4 Ohm.
EDIT: My circuit was not possible. Because of Safe Operational Area.
So I remove this circuit.

Are you sure?
The input to this chip are JFETs.
That is why I did not add such a capacitor.
There is no currents flowing into the inputs.
The simulations does not show any considerable DC-offset.

You may be correct.
SPICE sims THD figures is not to be trusted.
Real value may very well be what you say.
