Yes. The 568 has analogue and digital out so volume control would be unified across the different outputs but also needs 5S slave comms originating from a Master DSP speaker

However, if you are thinking of sticking with the Denon and adding the 568, I think you may run in to problems, not least with integrating volume.

Not sure if you are aware, but DSP speakers, including the D2500 expect a full range digital signal. Volume control information is then passed over the comms lead (you may be short of the M-lead that would be required between processor and first DSP speaker - IIRC that D2500 will come with the slightly different S-lead) and it is the DSP speaker itself that does the physical volume control using a hybrid analogue/digital control. If you attenuate the signal before this, then, IMHO, you are losing one of the key benefits of using DSP speakers, that is keeping full range digital signal rather than compromising/truncating resolution of the signal.

Just double checked Giannis comment below and D2500 does indeed need a DSP speakers slave output (directly or indirectly via a patch/Y lead) to operate.
