Well said. I originally said and thought I could build a better system for the same money. Frankly, I couldn't come close and even if I could financially, it wouldn't be close in sound.
Features, configurability and functionality aside, I've been making notes of the sound of the Devialet. It has a slightly sweet, slightly warm and liquid sound with amazing PRAT, depth of soundstage and the blackest backgrounds I've EVER heard. Such a controlled sound too, but with finesse. Every piano note is so delicately reproduced. Great separation. Incredible at digging out the finest details in recordings, yet not making bad recordings sound worse, quite the opposite in fact. The hall ambience of live recordings is clearly captured. When listening to the Devialet and quite possibly because of the black backgrounds, I feel like I'm all that much closer to the recorded event.
The ADH sound is quite something. It sounds like nothing else you've heard before (in a good way). What is ADH? It is a hybrid Class A / Class D operation throughout. Both amps work together in parallel. The class A drives output voltage and controls the sonic signature while the Class D amp drive the output current needed for high power.
