I wish people would understand that this is not designed for single channel preamp stuff like lead vocals!!! Yes, it's flat sounding, but that's what I like about it. I don't care for hyped bass or mid range etc., everybody EQ's later anyway so I don't understand the fuss about having a coloured sound right out of the box. I use my Audient for single channel stuff and the Focusrite Saffire Pro 40 + Behringer for drums and multi tracking. For loud sound sources like drums and cranked amps, I can't hear the difference between these midas preamps and the Saffire ones. Maybe on a quiet intimate vocal or subtle strings etc. you can hear differences but it's all about choosing the right tool for the right job. Why blow thousands on something which only gets used on extra toms etc. when you can't hear the difference anyway? It's disingenuous to do an A/B test on something it was not designed to do. The fact that it's ADAT and needs a host interface to piggy back off means that people only buy this because they need more channels for drums and multi-tracking. Nobody is buying this as a single channel preamp for vocals, so comparing singing tracks or solo instruments is pointless. This is an inexpensive expansion purely for when you need more tracks, like tracking a live band or recording drums.
Pros: Easy setup, flat uncoloured sound, quiet preamps, separate line-in inputs on every channel
Cons: There are none at this price point. Anyone who has issues with this has misunderstood its purpose.
