Looks like Devialet has developped their own DAC technology for at least the Phantom Gold. Perhaps they'll use the same base technology in the Expert ADH stage.
I almost can't imagine they've actually developped their own DAC circuitry/IC from ground up but perhaps they have, or they've just OEM'ed something that they may or may not have also integrated in their own ICs.
