Only vs the CX3400 IMO. The DEQ is a very versatile unit itself and for some of us can even function as a useful stand alone basic analysis tool.
The DCX while touting a parametric EQ function really only offers one band of EQ per output and input channel, and the extent to which you can push the parameters is very strictly limited by the amount of internal memory in use. Probably best to look at it as a crossover only, as it cannot really perform the function of a stand alone EQ, and certainly not one like the DEQ.
Another thing to consider is that the DEQ can be connected to the DCX in the digital domain maintaining the minimum in A/D-D/A conversions.
Just my .02....................
