Nicely compact with a pleasing aesthetic, sleeker in person than the pictures would have you believe. Build quality is excellent, surpassed my expectations. The unit gets slightly warm during use, nothing out of the ordinary for electronic equipment.
I use it in a Win10 home studio setup, drivers install along with CueMix 5 in a single installer, firmware update via CueMix took 30 secs, was up an running on my system within about 15 mins from opening the box. CueMix 5 is well laid out, easy to use, responsive and functional.
The OLED is a nice addition and is quite useful for quick metering and there are some settings you can change directly on the device without having to open CM5 such as sample rate and factory reset. Latency performance is good, nice and stable at low buffer sizes. Loads of I/O, the two pre-amps sound great, transparent, with lots of gain. DC coupled outputs are a useful bonus. MIDI I/O essential, ADAT expansion great to have.
One con: the Volume knob is small and right above the headphone output so can be harder to turn when you have a set plugged in. The knob is high precision but that also means it takes a few seconds to turn all the way down. As far as I can tell, there is no way of quickly muting either the headphones output or the main output directly on the device.
Overall very pleased with this purchase, does everything I need and more at a very high standard of quality across the board.
