For Vcc = 35V, the maximum peak voltage to the load for that circuit is less than 70Vpp. That gives less than 75W into an 8-ohm load. So if you want 100W (which is only 1.25dB more) you need to either increase the voltage or go to a bridge amplifier type of circuit (where both terminals of the speaker are driven out-of-phase). That can theoretically increase the power by 4 times. But note that the amplifier now has to be able to deliver twice the current to the load.
