FAWK MIXING TIMEZ! : DI's & Midi included

Hi,

i'm thinking about getting started with reamping with this DI's. I use a Line 6 UX1 at the moment. So if i wanna run the DI's through a real amp I should connect one of the analog outs to a reamping box like the radial pro rmp and then into the amp, right? Additional question: Do i really need a reamping box? Thanks a lot in advance, cheers!
