Since the ear does use the higher ordered harmonics to calculate sound pressure, the main thing is to not generate distortion such that the higher orders are present.
This leads to a more relaxed sound; IMO/IME the better systems out there will have no sense of sounding loud even when they are. IOW they will have an effortless quality at any volume.
Push-pull isn't the problem- excess generation of odd orders is. However I do agree that many or most push pull amplifiers do have problems in this area.
I also agree that speakers that are easier to drive (and IMO, higher impedance as well) are quite a boon as it then becomes possible to have some serious sound pressure without a lot of amplifier power. Some amplifiers (zero feedback in particular) are best run such that the output power probably does no exceed 20-25% of full power. This helps keep the distortion down, often to the point of inaudible and unmeasurable.
