Gustard X26-pro test
vanson1, I see Gustard multitone performance is the best achievable, and that is the most important DAC perf-metric. third order is about -125dB, which is perfect. Third order harmonic increase over topping is because Gustard has discrete class-a analog signal path, which on my experience is better than regular OPAMP chip design.
