Good news if the analogue stages of the DCX2496 is so bad.
So the improvement of a modified unit should be worth the ekstra work,
and remove some of the x-overs negative influence on the sound.
Which is always good to know beforehand.

There's always compromises, of course, but with an all horn setup
the plus outweighs the minuses, IMHO.

Have you looked into using computers for x-over duty?
Jan,

It is not about the compromises but about the fundamental damage that DSP inflicts to sound. People who use digital crossovers, because sound was already screed by the crossovers, juts do not know how their drivers perfume in reality. I’m not even talking that the people who use d-crossovers have no touch with driver’s needs as the drivers could NOT be use in their environment without being digitally crossed. How do you know how your drivers really sound at the given ranges? How could you say that your digital crossover “does well” if you have no ways to use the drivers without digitalization?

Anyhow, I did not look for using computers for x-over duty. It is not about the computer vs. dedicated crossover box, of better A/D, D/A, or a better output stage. That all is hard to accomplish but it is accomplishable. The problem begin what you inject a digital slop into auditable range, loosing resolution and injecting sonic fog into each decibel of lowered volume.

There is an unavoidable rule: digital can’t filter, analog can’t delay (practically at LF). It is like humans do not eat sand and do not drink ocean water. Sure, it is possible to do it and call it “compromise” but what the purpose. There is HUGE amount of benefits (not only sonic!!!) with analog filters. I do not call using digital filters as compromised but rather a victory of wishful thinking over a sense Realty.
