The Axxess Forté series of integrateds are the best implementation of Class D I have encountered, both integrateds and separates. I suspect that’s because their distortion profile is 2nd order dominant, with all higher orders being inaudible. They are rated at 100 WpC, but actual output is approximately 170 watts into 8 ohms and 250 watts into 4. The onboard DACs are stellar too.
