Question

Does a headphone amplifier provide better sound quality, or is it solely for higher volume levels?

Answer 1

most change just the volume, but some have equalizers to change the sound

Answer 2

Any amplifier actually slightly degrades sound quality. It trades (albeit a small amount) of quality for volume. Some amps have EQ's (equalizers) that will allow you to adjust things to tweak out the sound you are looking for.

Answer 3

A headphone amplifier will not provide better sound. Amps are designed to increase amplitude with minimum distortion. It's mainly for higher volumes. For better sound always make changes at the source.
