This is technically an incorrect statement since technicalities is FR since again on minimum phase devices it is the most important thing by far before we go into other aspects like distortion which even then don't seem to matter as much as is often assumed on audiophile circles.

Good example would be the Moondrop Chu which is often considered technically mediocre due to "low bass impact" (Which I guess is true since they are a bit light on the bass but eh) so people speculated it was due to high distortion in the drivers yet distortion on them is fairly excellent in practice even compared to much more expensive sets.

Now though whatever or not we can correctly define what (to an extent subjective too) aspects of the FR (And that's talking about FR at your own eardrums and not FR graphs too) constitute "technicalities" is another matter entirely and that's without mentioning subjective bias you add into the discussion that doesn't have anything to do with the inherent properties of the transducer like price for example.
