Hi, I have this mixer. 8 Channels, 3 Groups and 1 master. The feature set is really great and also usability has been well though through. A couple of remarks are however:
- draws a lot of power and also gets very warm
- I use it in a Doepfer base case in the bottom row. The input jacks collide with the top row and therefore it is not easy to patch the inputs when top row modules are patched as well
- In my case I also use a lot of FX modules and many of them are of course digital. They also draw a lot of power so I am having issues with noise/hum. I have been moving power connections to other bus boards but it is not perfect yet.
- The Send Return knobs are only Poti shafts, that makes it more difficult to control them

So, all in all I am very happy, due to the facts above I might be moving it to a own case.
