Why isn’t more detail always better?

"Details" or "blooming" are adjective used by people describing their subjective impressions.

These impressions can be taken negatively or positively...

They are not acoustic concepts.

I look and design my system/room to gave me natural timbre with all spatial attributes of a located and 3-d sound... With the gear system/room available for me...

I look for his optimal working which will be astonishing if i succeed nevermind the price or branded name ( I dont say that there is no difference of potential quality level here take note )

To reach this we must learn how to control the acoustic parameters at play... There is no kingly road to a good sound

This has nothing to do with the gear price or branded name. ( it is evident that some gear are better designed than other but it is not my point ).

The sentence : i want more details or i lack details or i had too much details is often an expression of our impotency facing a disturbing acoustic experience. It was for me before i learned how to use basic concepts in acoustic.

As remedy we must experiment with mechanical vibration/resonance controls, electrical noise control, and especially acoustic and psycho acoustic numerous parameters variation in experiment ( i used my own devices to do this).

I think, define, bloom as an "expansion/increase in that area of the lower midrange where the fundamentals of vocals emanate from."

Furthermore, I think that I could even make a demo showing this effect in real time (i.e., A/B). When I raise the crossover point on the Mermans from ~310 to ~350Hz in the JBL 2241H 18" and boost it by ~1 dB, it really impacts the vocals which come alive and take on a more realistic effect.  I can do this remotely at the flip of a switch for instantaneous comparison.

I actually look at bloom as “lack of attenuation”. Unless it is actually in excess of live sound that is what it means. But I think over representation of midrange was something that happened a lot mid-twentieth century, but not much now… well at least among high end gear.

Simple,  all these wordy opinions , are just that.  KISS principle, keep it simple stupid.  Every one into good sound has their unique opinion concerning detail.  Just  hear your own sound.

One aspect of "detail" that shows up in some systems to me is an unnatural separation of sounds. For instance, in my quest for new speakers I listened to a few very highly recommended models that made a cymbal sound like separate instruments (being struck and the resulting shimmer) and fingerpicked guitar where some string squeaking was front and center and completely separate from the guitar notes. I settled on speakers that (in my system) gave up a little "detail" but, to my ears, kept a smooth and natural transition of sound from each instrument being connected and continuous.
