I meant the actual DAC IC in the 210eq and the 4000x, could you replace
the DAC ICs in the 210eq with the same ones that are in the 4000x.

I think that is highly doubtful, the two have completely different circuit 
designs.  The D/As aren't even the same brand (Crystal Semiconductor in the 
4000x and AKM in the 210EQ) so I think it is VERY unlikely something like 
that could be done.

Ah okay... AKM makes some DAC ICs used in some decent modern DVD players
(24bit/96khz I think?)

Any knowledge about the extra IO port on the xdp210eq? It looks like it
might be close to the unilink bus judging by the schematics for the unit.
Was there windows software or at least some way to talk to the unit via
rs232? I guess it would be possible to talk to it using the GNUNILINK
software, but you would have to reverse engineer the EQ/DSP portions of
the unilink protocol and emulate a head unit... nasty.
