Reply to Audio 2 DJ & Reloop DJ Controller

newbie here. ok so im looking at buying a digital controller, im believeing about the reloop digital jockey 2 interface edition, but i wanted to know if people would recommend getting the reloop digital jockey 2 controller (no built-in soundcard) and Audio 2 DJ with this?

an improvement of sound? may even save me money.
but the real query is about the outputs, the fact it has jack outputs works for me as my monitors are the same, but i want to know how can i connect my monitors up to the A2 sound card and still get a headphone cue, when it has only 2 outputs, is there a way to do it? cable splitter?

cheers
