I asked about Reactor Custom to Devialet support a few days ago. The answer was: "Yes, the ADH3 can handle 192kHz on our product". ADH2 is used in Gold/Classic (and Silver) plus in the Expert Pro amps and can do 192kHz, but you might be right that the DAC in Phantom I is a 96kHz device.
96kHz in Phantoms would be fine for me too
