Same patches, same parameter values, different sound. So it might not be DACs directly, but something else in the output section. It's not EQ, though, that much is apparent.
I'm not disputing that they sound different. I'm saying it's highly possible that Korg (along with other vendors) made successive tweaks to their sample base and may well have compensated for artefacts they introduced by making compensatory changes in the analogue output stage – which would be effectively a static EQ or at the very least a change to the cutoff profile of the low-pass anti-imaging filter. And that the DAC is last place you are going to hear much of a change, which seems to be confirmed by the use of the same part across several generations that sound different.
Also, component tolerances: people just don't design this gear that badly, at least not by that point in time. If they did, individual units within the same family would sound different.
