Hi folks, I was wondering why people spend so much money on their DAC for a headphone while DJs fill clubs with sound using audio interfaces. Generally, they seem to cost more, but there are audio interfaces for 600 bucks that give you 10 channels. So on the price, the DJ audio interfaces win. So anyone knows if a DJ interface like the super tiny Native Instruments Audio 2 DJ (http://www.native-instruments.com/#/en/products/dj/traktor-audio-2/) would work for audiophiles? Would it give you more SQ compared to your built in soundcard? Remember, clubs spend lots of money on their stuff and there are really DJs using this thing. Or are they useless for enjoying music as you are almost all using DACs concepted for headphones? Anyway, an amp is needed anyway for bigger headphones, am I right? DACs are nothing else than soundcards? Thanks for help and please excuse my bad Englisch.
