"Perfect hearing" as described above correlates to the upper frequency response of the system and, mostly SPL. That's only one parametre -- and, outside a FR window (say 15-16kHz), not the most important one IMO.
Coherency, correct reproduction of instruments in relation to one another, etc are more important. So an experienced listener (reviewer) even with losses over 15-16kHz should be able to give a good report on what's going on.
As always, personal "bias" or taste isa important to understand if the writer's opinion is consistent and thereby, of any value.
