Nothing to complain about: it's a magnificent gadget. Quick settings (especially from the computer), ease of use, very low latency (beware of USB/FireWire power supplies that can slow down transfers to PC/Mac, but even in this configuration the latency is much lower than cheaper sound cards), stunning sound quality... You know where your money goes. I bought it to expand my possibilities, to be able to manually manage effects on the buses (outputs of the card) externally in addition to the buses of my DAWs, and to adjust the panning on the console (for example). In short, excellent gear.
