Devialet into other power amps?

[Dr Tone]

The DAC is an integral part of ADH, which also incorporated the preamp function, so what you wrote is nonsense.

FYI: 

ADH stands for "Class A" "Class D" Hybrid.  The "D" in class D does not mean digital, it's still analog.  The DAC has already converted the signal to analog for the ADH model.  Thus the DAC has nothing to do with the ADH power amplifier.
