You know, for playing audio loudly? I miss having ready access to a selection of portable sound systems for musical mayhem.
Cory Doctorow points at some lightly modded consumer class-T gear
James Nichols advises:
Yes - class D amps are better and cheaper than ever. This is the smallest, cheapest, and most surprisingly reliable option. Otherwise I just bought one of these and it really is almost 2 x 100W. Hypex is much more expensive, but actually proper hi-fi. These cheap $20 boards are good enough but totally expendable if you want them to be. Also of course - the two boards I linked you to are both 12-30V (ish), which means they are 100% battery suitable. Typically the best configuration is to put two 12V batteries in series to get 24V - at higher voltages the boards are more efficient. If you want to run off mains power, then that Yuan-Jing site has power supply options.
