This includes a 220uF capacitor and two diodes to slow down the switch-on to reduce the output thump as the output capacitor charges through the speaker. This is not essential, depending on speaker sensitivity, with my own speakers there is just an unobtrusive low frequency sound at switch-on. With other applications such as a bi-amp [...]

I propose you here a basic MOSFET amplifier. Output power is +/- 100 Wrms under 8 ohms or +/- 160 Wrms under 4 ohms. Due to the circuit simplicity, distortion is +/- 0.1 %. Bandwidth at -3 db is from 4 Hz to 96 Khz, it is limited by C1, R1, C2 and R2. Transistors [...]
