I have a pair of DT770 80 and I've had them for maybe half a year now. What I'm wondering is that if I use an amp will it be any different from having it plugged to the mother of my PC or my phone. I've always thought that, yeah this can produce sound that is way too loud for the health of my ears so it should be fine as is, but does having an amp make any difference in the sound quality?
On an extra note is the only point of an amp driving up the volume or does it change other things too?
