There are a few design flaws in the conception (the switches are noisy and the unite rack is far from perfect for example) but for the price it's pretty awesome.
I was pleasantly surprised by the pre. It's plenty usable with tons of gain and not as much noise as expected, you can push it in the red and get "that kind of analog warmth" without it sounding sketchy.
Only fiddled with the eq for an hour but, so far, so good.
