If you do the DAC first, you have an analog signal, so there's no problem following the DAC with an analog crossover, which then outputs two pairs of analog signals (one pair for the mains, one for the subs). That's what I'm thinking of switching to.
But if you do the DAC first, you can't use a digital crossover, because the signal is in analog form, and a digital crossover works on a digital signal.
I suppose there is some gear that implements a digital crossover on an analog signal. But to do that, it converts back to digital first, then runs the crossover, then has four channels of DAC. In my mind, the repeated conversion between digital and analog domains is best avoided.
Clearer?
