hello all

i am comparing three audio interfaces:
1/ M-Audio - Fast Track Pro
2/ Novation - nio 2 | 4
3/ Native Instruments - Audio Kontrol

I want to use it for live DJ performance and was looking for stabilty of drivers and sound output quality above all else.

I am usually an RME user but want another option that powers soley by buss (with the intel macs, you still have to boot from power with firewire 400 due to lower voltage ports)

can anyone give their opinion here?

many thank
