Hi, I've been drawn into the audiophile community a year ago, unknowingly after I was looking for a pair of IEMs and Google brought me into this forum. *curses* lol. I'm still trying to relate some of the sound terms to actual experience.
How do you differentiate between mid-range and treble when you're listening? Are female vocals that sing in high-pitches considered in the treble range?
How does a headphone amp work if it is plugged into a soundcard output in which the soundcard has existing built-in amp? Wouldn't it result in a "double-amplification" in which noises would also be amplified significantly?
Welcome to Head-fi Ichigo-kun!
Take a look at this interactive chart. http://www.independentrecording.net/irn/resources/freqchart/main_display.htm
Move your cursor over the chart and pay attention to the description in the top right box labelled "Spectrum data"
Female vocals are illustrated as a separate range.
DAPs and souncards typically have a separate DAC (digital-to-analog converter) and AMP (amplifier) section (among other components). The DAC output is fed to the amp and the resultant signal is what we get out of the headphone out port. Some DAPs and soundcards will have a separate port called "line out", where-in volume and power circuits are bypassed. Here, since the signal is diverted earlier in the chain it is considered purer. Double amping will result in the signal being passed twice through similar circuits which is sub-optimal. In the absence of a line out port the headphone port is used, and results in double amping which may adversely affect the quality. Some devices like the ColorFly C3, due to the way it is implemented, delivers a very clean headphone-out. In such cases the effects of double amping are less noticed.
This is of course, a very general explanation. Hopefully it will help you narrow your doubts.
