"Sounds superb" is in the ear of the beholder, so I will have to accept your judgement at face value. I have built active crossover using better circuits and better component than Behringer would be capable of, going back to Tresham days for large PA rigs, and experimented domestically, and in my opinion
just as with this latest fad for balanced line for home hi-fi systems it is a misplaced compromise.
Just because something is needed and works in the pro market doesn't make it the best compromise / solution in the domestic market. Most of it is just marketing hype anyway.
