You are right about the reactive load. It is another of the problems of the current electrical grid, especially if you live near supermarkets or industrial centers a few kilometers.
Well, the HF noise injected what interest us is usually inside the LF (< 300 kHz) and MF (< 3 Mhz) bands that surround us, then we say the same. It is the noise/interference that must be filtered in class A and AB.
In class D, the > 1 Mhz must also be taken into account. That interference many people have not taken into account when building amplifiers in class D, accustomed to the problems of class A and AB technologies.
