If I have a pair of M-Audio BX8 Carbon's and an M-Audio BX Subwoofer, is it recommended to get an audio interface? I don't know much about them, except for the fact that they act as a sound card, and are more powerful than the one's built in computers. However, I probably will need one to maximize the quality of sound recording that I will be doing in composition.

I have a late 2014 Macbook Pro, so what is the best option for an audio interface? What kind of cables would I need, and how would I set everything up?
