Secondly, why do DACs have such high output impedance while amps do not? That leads me to believe an amp is almost always required, or maybe I am not understanding something here.

Soundcards are basically DACs that have a "it's something
" amplifier. Pure DACs are not made for stand-alone usage, they always need amplifiers.
Think about the power needed to make the headphones and speakers produce sound:
- DACs have so little output power that they can only tickle headphones (or sound crappy).
- Headphone amplifiers can amplify the signal enough to drive headphones, but when it comes to speakers they can only tickle them.
- Speaker amplifiers can amplify the signal enough to drive speaker elements, and on occasion they can also be used to drive monstrous headphones like Hifiman HE5-LE
Like the name tells, DACs only handle the conversion of the digital signal to analog signal. Amplification is handled separately.Edited by Tiihokatti - 5/13/15 at 8:05am
