This was one of my concerns (the other is the AD-DA conversion, which I still need to run some tests on, but suffice to say at this point that I do not notice digital nasties. At all.)
I have tried very hard to pick out a coherence issue. Listening to various kinds of music at various volumes, unfamiliar as well as the numbingly familiar, I cannot say there is anything going on in the crossover or in the fabric of the music as it is handed off between lower and upper. It is important to note that you should work at the gain in the crossover, even if your amps are of like gain. I have not tried two identical amps so can't say there, but likely that will be ok with the factory settings.
I alluded to the benefits of two amps earlier. The gain adjustability is part of this flexibility for me... on some recordings which are voiced hot, I can drop the upper gain perhaps 1/10 or 2/10 of a dB, and things are more listenable. Perhaps the purists will barf all over this technique... I'm not a purist. As I said before, I know what I like and I like a system that lets me tailor the sound within reason.
