Default Electronically, is a headphone amp just a clean signal boost with impedance buffer?

Well that's what I gathered so far... is a headphone amp basically a clean signal boost, with on some an impedance adapter? Just curious mostly.

Pretty much, except the "clean" part. It just takes the signal coming out of the MP3 player (clean or not), presents some really high impedance to the DAP (100s to 1000s of ohms), and then increases the voltage.

Basically a headphone amp gives you whatever the "unloaded" RMAA test gives you, except it does it while driving headphones. Plus maybe a little bit of extra noise if the amp isn't very good.
