PRETTY MUCH.
A amp hasnt changed much in basic design ever since Lee Deforest invented the vaccume tube.
Its basically a valve controlled by an input source.
This allows a voltage/current that can drive a loudspeaker.
But its never the signal itself driving the speaker , or phones.
The source just controls what drives the speaker.
There is no real technical reason you cant have a high current speaker, but it will need voltage.
All I am saying.
