i know i'm jumping into the subject late , but what do you all mean by technical brilliance ... ??

is it the dj skillz on the turntables 2 or 3, , the mixer, versitality in using the effects , good eq , versitality in style , blending the elements togheter , choping, improvizing on the spot , being able to properly do what u wanted on the decks in the first place just by thinking about it ?
