Devialet's newest technology...?

Indeed, what's this "expert line"? Perhaps it's only a poor translation from French but they also name it an output.

Suggests to me that you can stream audio from the Phantom to (e.g.) an amplifier with a USB input. Like an existing Devialet, perhaps?

Could that spec sheet be for the Dialog perhaps?

Yes, I think you're right - the processor/memory specs are higher than shown for both the Phantom speaker units.
