It all depends on how the output source is designed. Many DACs and such are current-limited, as they're made to power loads of a couple of kilo-Ohm, such as amplifiers. Others are designed to power <100Ohm loads, and are thus much more powerful. There is more than one kind of DAC out there, you know. It's an active component.

.Sup wrote:The sole purpose of Digital to analog converter is just what its initials say. DAC does not output any power, thats why we use amps. What DAC does output is not power but signal. Every signal needs to get amplified if you want to hear sound and standalone DACs don't have amplifiers hence no volume knob on any of them.
Normal headphones don't need a lot of power to run. You can plug an amplifier into an MP3 player without turning the volume to the bottom.
