Hi Garfield,
Yeah the WMD impressed me on par with Noise Engineering BIA for hard hitting percussion modules. My Doepfer monster base case just arrived today but unfortunately I cannot stack the two 6u cases on it :-(
So I will need to order a regular large Doepfer monster case next year to stack on top. It works out as I can take the modules from both 6u cases and consolidate into the Doepfer monster case next year for one setup after I add another sequencer and more FX to it. Then use the 6u cases for travel purposes even though the base case is portable as well.
