Somehow people cannot comprehend that class D amp is purely analog and switching itself is inaudible. Switching is present all the time - even without input signal. Place ear against the tweeter and you will hear very low typical amp’s hiss - likely much less than with any class AB amp.
That wasn’t my experience between a Spectron Musician III mk2 (Class D) versus a Sanders Magtech (Class AB). Although the Spectron is quiet, it’s not as quiet as the Magtech. Both are inaudible at the listening position though.
