How loud do you have to listen to fully power a driver? Say you have a headphone that's hard to drive, but your amplifier gives them a sufficient loudness with plenty of headroom on its dial. What exactly dictates a headphone having more power and dynamics while having the same amount of volume? I guess I'm talking about the damping factor but don't really fully understand it.
One personal example would be my DT990 600Ω. Through the Little Dot I rarely have to boost the dial above 20% to get sufficient volume. However, when I up the volume I don't really notice an improvement of dynamics either. Then I hear some people with more powerful amps having to boost the volume on their dial to higher percentages, but supposedly those said amps can give better dynamics. Is there such a thing as an amp properly controlling its power? Is there such a thing as getting a driver to provide its fullest dynamics and achieving its best control/impact without giving it gobs of power?
