Does anyone have any knowledge of this : https://www.numark.com/product/ns6ii

It ticks a lot of boxes - 2 usb inputs, 2 controllable mic inputs etc however I am mainly a denon/pioneer person so would like any advice.

Years ago I used a Numark Mixer which done the job and was bulletproof, however changing over to a Denon Mixer really made a huge difference so unsure if it will be similar with this controller.

The 2 usb inputs are what attracts me mainly, I am a bit of a backup freak and have 2 macbooks running throughout a disco 'just incase' and this looks perfect for that.
