I just watched the whole thing and it was pretty entertaining!
I feel that it is a bit "biased" - we all know mr zabiela is probably paid a lot of money by pioneer and maybe native instruments/ableton? Also the lack of any turntablist as a judge (other than kutski) is a bit odd, some gears were not well-demonstrated (they didnt have anyone performing sick kuts on the ns7 - i saw better videos on youtube than what they showed off with the ns7!)
aniways you be the judge - i'd personally pick the dns3700 over the cdj400s anytime! And also i agree with kutski in that GRIDDING in traktor can be frustrating for vinyl-ripped or slightly inconsistent tracks
