The ACA Mini has become one of the top recommendations as an answer to the question "What amplifier should I build first?".  The entire project can be completed in an afternoon or two.  It's perfect for dorm rooms, small spaces, dens, listening rooms, and everything in-between.

The Complete Build Guide and the full kit with all the parts you need, make this project accessible to almost everyone with a soldering iron and some basic tools.

And... it sounds pretty fabulous too.

Pair it with an ACP+ for an absolutely amazing headphone amp, pre-amp, amplifier combination / mini-system.
