The other advantage of easier to drive speakers is the amplifier, regardless of technology, will make less distortion. That will result in a smoother and more transparent presentation, since a lot of that added distortion will be higher ordered harmonics to which the ear is keenly sensitive, and otherwise distortion tends to obscure detail.
Absolutely, that's a very important aspect I failed to mention - thank you. And sadly very few speakers made today are 16-ohm load, which it seems is another means to lower amp distortion. Not least also having an amplifier only cover a limited frequency span actively, like freeing it from the lower midrange on down, is a liberating measure to lower distortion.
