As far as I can recall......
When the M32 was launched, they were crediting the sources/algorithms for the FX on the M32 page. There were references to the Behringer name (amongst others) from the source units. I think at least the "Combinator" and "Edison" were/are Behringer units. That's if my memory serves me well, I might be mistaken but I don't think so. Why they did it is just marketing IMHO. Midas filters down nicely to promote Behringer products but not so much the other way, no matter how good the product is.
I'm baffled by the pricing, I'm sure tax plays a big part as you say. Regardless, it's pretty unfair to local customers. Maybe I should have sent a signal by not opening my wallet, but when you want/need something for a job, rational thinking takes a back seat. Marketing again undoubtedly dictates the European regional price, probably to keep it in line with other product lines and manufacturers here. There is a mentality that "more expensive equals better". I've been both victim and perpetrator of that myth.
Anyway, I take it you have your X-Rack all sorted and running the way you want it by now? Haven't been hands on with one yet but would consider one when the DL needs replaced
