Reply to Controller Sound Doubt

Hi!

I just bought a Numark Mixtrack PRO White Edition a few days ago, and I'll receive it in about 2 weeks
I never used a controller, I allways played on the disco I was resident, before I moved to another country, using vinyls, only vinyls, but on this country is impossible to get vinyls, at least, minimal, tech-minimal or deep house vinyls, so I decided to get a controller to use it with my mixers as it was a double CD player (I have an Allen & Heath Xone 92, DJM800 and Ecler Mac 90, but I use mainly the Xone 92 with external effects (Kaoss Padd KP2))

My doubt is: will the sound be worst than a vinyl?, and how worst will it be?
Thank you!!
