Reply to A&H Xone 4D

Hi Guys;

Does Xone4D traktor certified.. I have seen lot of grandmaster DJs still uses xone 3d or else couple of x1 kontrol in their set. Can anyone please advice me whether Xone4D is a good investment? and How about latency figuers on 20 channel sound card?

What I'm believeing is if I get xone4d I only have to have single usb connection for all where as if I use external sound card, two x1 and other it would complecate my setup. What would you believe? any ideas or anyone own xone4d in this community ? Please help!
