Really?

"But in addition to that power, the distortion components that the ear finds as the most audible (IM, and the higher ordered harmonics) will have to be kept to a minimum. That's hard to do when you have a lower impedance. In a solid state amplifier, the output devices have a non-linear capacitive aspect built into the junctions. This capacitance is magnified by current (BTW, the FM radio in your car is tuned by a device called a varactor diode that takes advantage of this principle). If you want to avoid the non-linear capacitive effects on the circuit, its to your advantage to keep the load impedance higher.

Now you can see this sensitivity to load in the specs of any amplifier, even class D."

So I showed you an example of a class d amp that is not sensitive to load.
Similarly, the IM it produces is below audibility.

Some call this "sterile". I call it accurate.
