The term wants to evoke an impossible ideal - one that will shift over time with different theories and understandings of how to relate headphones to loudspeakers
Headphones and Loudspeakers can't really be compared and they shouldn't. I agree with most of the other things you said except for your description of the K702, lol. I think the K702 sounds perfectly natural.
