ok now that my rca-aux cable has stopped working, I cant use my monitors, so I think its about time to buy an audio interface, however im pretty clueless on the subject. I guess my question is, what is a suitable audio interface for a 13" macbook pro and KRK 8" monitors. I was thinking of using the XLR inputs on the monitors for the interface as my dj gear uses the rca inputs if that'll work?
