Ultra-compact LM4780 audio amplifier
Here is a very nicely built audio amplifier.
It has it's own dual power supply, very simple schematics for the amplifier part and nice looking box to fit it all inside. It is based on LM4780 IC which gives 60W per channel (and it has two channels). No PCB was designed for the amplifier part since point-to-point wiring was used.
