Again, Behringer is uppering the performance/price bar. This device is unbeatable, full of feature, rock solid, completely supported. It is a winner. Good preamp, MIDAS designed (be carefule, it's designed, they're not MIDAS manufactured), the sound is clear and powerful. I've also tested live, it is solid, it works like a stream. It is also a good audio card, it can go low to 2-3 Milliseconds OUT latency and about the same for IN latency. Good effects, I would say effects are at least as those in X32, which I've used quite a lot. In particular, I like vintage effects emulations.
What I like more: full routing capability. The routing is extraordinary and I like so much X18 configurability. It is
What I like less: of course the ability to configuration (you have no faders or buttons) and the 6 Aux outs, which are TRS and not XLR. A double phone out would have also been a Godsend.
Last two cents: Wonderful mixer, good audio card, extremely sophisticated routing, great configurability, the perfect companion for the studio and the live!
