Hello I decided that its time to upgrade my headphones. After a lot of research I chose the Audio Technica AD700. A lot of people say that these provide the best positioning audio on the market and thats why I liked them. My only concern is that I the built in soundcard in my Asrock P67 Extreme4Gen3 is going to hold them back. Do you think that I need to get a Dedicated sound card or I will be just fine with the built in one?
