The speakers/ room relation is to be build around not only with room treatment but some mechanical room control...(Helmholtz resonators and diffusers)
After that say bye! to most futures gear upgrades....
When music is there for the first time in your life, you forgot sound/gear upgrade...
Flagships products are too numerous at all price tag to be the center of focus... Pick one, chose well, and concentrate on the relation between acoustic/psycho-acoustic...
Or like most, ignore acoustic/psycho-acoustic and go for decades changing one piece of costly gear for another one and call that your taste...
😁😊
By the way there is no flagship "taste" in acoustic....Only a specific ear/brain tuning subjectivity at the command center of the acoustic journey and process....
