Your observation correspond to my experience in acoustics evaluation...
When things got right with gear synergy in a not too bad room, we live through a minimal acoustic satisfaction threshold ... This minimal level suppose in spite of some inevitable limitations a relatively good balance between all acoustics factors implied and when we live through it the first time by luck or/and by good planification , we feel a small ectasy or at least a great pleasure ... It is sometimes enough for many if not most people ...😊
Anyway to go further luck and gear synergy and a not too bad room will not be enough...
We will need if we want to go to the maximal acoustical satisfaction threshold, to recover this balance between all acoustic factors on a higher level of experience , we will need if not higher quality gear design upgrades, at least embeddings controls devices and means and tools in the mechanical, electrical and especially acoustical working dimensions of the system/ears/room ...
Acoustics is the main factor of audiophile experience and acoustics is more than room acoustic here ...
Thanks for your post...
It was a sub 2k system that was so satisfying had I started with it I might’ve stopped there.
