Unlike many, I like to check things for myself and more when they go against or are not in line with my academic knowledge about it.
So far everything Danny Richie says I have been able to verify. Many others just give their opinion without testing before. Costing so little money not to do it before commenting... How it starts showing off speaker and room measurements without having read Floyd Toole's famous book.
You might be forgetting the fact that I actually tested/auditioned this pair of Behringer speakers. So, using your premise, my opinion is valid here and yours is not.
Regardless, there is another variable here that might be overlooked. (And just mentioned by jtwrace.)
The Behringer speakers were modified such that the "high-quality" crossover emerged from the box via the tube connectors and the original via the banana jacks. This necessitated a different/separate set of speaker cables to interface with the tube connectors. Danny supplied those cables with the speakers, but (obviously) when you A/B'd the original crossover with the "high-quality" crossover you were using different speaker cables. I measured the LCR of those cables, and they were different than my normal cables.
Much depends upon the power amplifier used as to whether it was a significant variable. For auditioners that used a power amp that was near a voltage-source, it probably wasn't significant.
Of note here is that Danny Richie uses amplifiers that are most definitely not voltage sources. At the time I believe he was using some sort of expensive Dodd Audio tube power amplifier with significant output resistance.
Just one of the many things to consider here.
Dave.
