in particularly pay attention to the Jean-Michel Le Cléac'h comments. A few years ago I was bitching that DEQ2496 sound like crap and here was the Jean-Michel reply. I think he is in on something and could be very correct:

Hello,

If you just took the Behringer and put it in you system as you said I am not surprise that it sounded bad.
Did you put any attenuators (by example -20dB) or step-down transformers on the outputs in order that the ADC (if you use analog inputs) and the DAC could operate at their best? If you didn't I agree that your trial was disapponting.
When I first replaced my previous active Kaneda crossover, which one used discrete stages and was excellent with the BSS FDS388 I was really disappointed. The sound was dirty, noisy, harsh... then I measured how many volts RMS I had on the input: 80mV. This meant that I had +37dB digital noise added. Then I put step down transformers and attenuators on every outputs and feed the inputs at high level (attention to clipping!)this was the best crossover I ever possessed. Please notice taht I have also tarnsformers at the input and that the crossover input lines and output lines are balanced.
Many members of the discussion group in French of which I am moderator then did the same: putting attenuators or step-down transformers on the outputs and most of them report excellent sound. Did all of them are nuts and must also suffer your mockery?

Best regards,

I do not want to convert this subject into the DEQ2496 but I thigh that you might find the reference useful.
