I’ve used this gear very intensely for more than three months. It has worked perfectly, without any problems. Futures are very good (2 x USB input, 2 x output: XLR and cinch simultaneously). Only the design and handling are for me not perfect: In the practical usage I would have more technical boring design: Power on/off on the front, normal display for input parameter and volume, a little higher foots, not glossy front-plate, the strange update procedure... Nevertheless I bought it for the function: make music from bits :-), and it’s state of the art and make me happy (without any doubts 5 stars) – the sound is for me really big show!
