Reply to Choosing a Interface !

Hello everybody! I'm about to buy a new audio interface that can be useful as a studio interface and for live "DJing"... I put djing like that becouse the thing that i want to do is to use Traktor OR Ableton and control it with iPad Lemur's app. So I need outputs for Master (mixer) I'd like a return for my KRK's and for Monitoring(Headphones) ... For studio I need a basic one, 2 Inputs will be great, with phantom power for the mic and midi for connect the iPad.

After searching and reading a lot on internet I have 2 main interfaces in mind: Native Instruments Komplete Audio 6 and Focusrite Scarlett 8i6. But I got a question on those 2 Interfaces... May I be able to monitor with the "MONITOR" Output on eachone?

If anyone could suggest some other interface I would be very grateful too Thanks!!!!

EDIT: I just saw the Focusrite Scarlett 2i4 and I believe is better becouse it has the 2 TRS outputs for my KRK's and 2 RCA outputs, 1 for the mixer and the other I could use some RCA to TRS jack for my headphones. My question will be... Could I use the TRS 1/2 out and the RCA 1/2 simultaneously? They were playing the same so there will not be problems for the setup.
