WHAT IS NANOSOUND AMP^2

The new amp add-on board for NanoSound DAC, NanoSound Amp^2 (Pronounced as "Amp Square"), include both a headphone amplifier as well as a very efficient 5W speaker amplifier.

It runs very cool due to its up to 90% efficiency allowing the whole unit (Raspberry Pi + NanoSound DAC + NanoSound Amp^2) to be powered by one single microUSB cable with 5V 2A (or individually if you choose to). It's surprisingly loud and is enough to power a large room or a small lounge as demonstrated.
