Thanks for your analysis Max - many things there I had not considered.
I'm sorry that my tongue-in-cheek and far from literal metaphor of a 'Chinese rip off' was not taken with the intent intended - I too like and use B&C, and they have been most helpful with information regarding the DCX464. It would be insane to think it is no better than the BMS, but the launch of the B&C driver just seemed so flat, with potential customers such as me wondering why I should take the risk.
BMS are one of the few driver manufacturers to offer distortion plots, and I feel that if B&C had done likewise, many concerns would have been allayed. I suspect that the design and production arms have done a fantastic job; the marketing, less so...
Looking forward to A/B comparisons.
PS. Yes, I get that Behringer connection too!
