Hi, This is an interesting discussion. Common, 802.3af P.O.E. is limited to 15w. Fine for a Raspberry Pi, DAC or DSP, but not enough for much amplification.

Perhaps for very small speakers with a low power digital amplifier, but anything decent would require mains (or DC batteries) to the speaker. The available current may power the DAC though.
