The rating on the speakers is their maximum rating, not their nominal rating. You can drive the speakers with an amp capable of anything up to 100W, provided 100W is their RMS rating and not the peak rating.
Delving deeper into the specs for those speakers, it seems they're each 50W RMS.
Given they're 8Ω nominal, that means they need maximum 20V RMS, 28V peak to fully drive them.
The HiFiBerry DAC & amp could take up to 24V for its power supply, so in theory could give 36W RMS to each speaker.
But that, of course, assumes you like listening to sine waves.
