Because components at a certain level, the very best ones aren’t really doing anything.
The perfect component does absolutely zero to make the sound good.

Therefore, if you find something really good and you go to listen it is only going to reveal all the other crap in the system.
This is why I never bothered to go listen to Moabs even though I could have. If they are as good as I expect then I will only hear whatever they are connected to.
Your post reveal a general misunderstanding in audio customers community...
There is a fact in audio: What we listen to is not the "component" sound first and last...
For sure the quality of dac,turntable,amplifier and speakers is an UNAVOIDABLE fact also with which we must compose when buying what we can afford ONLY.... Then never the best for most of us.....
BUT what we listen to FIRST is the acoustical cues collected and filtered by the recording engineer, and what we listened to is delivered to ours ears by the gear but LAST TRANSLATED by the acoustical controls or lack of it in our room.... The acoustical cues of the recorded event being conveyed by the gear are RECREATED by the acoustical dimensions of our room.... We never listen to speakers, we listen to speakers/room....No piece of gear at any cost can replace acoustic laws playing between speakers/room/ears....
Ignoring that you claimed that you dont need to listen to the speakers, being Moab or anything, because " I will only hear whatever they are connected to." You are not completely right here....The speakers are not only connected to an audio system but to a room....
Then i think myself that the fundamental fact of audiophile life is acoustic treatment and more than that acoustic controls....
And anyway there is no " perfect component", contrary to what you just said, and any component add something of his own, this something added or substracted from an alleged "perfection" or imperfection can be corrected in a relative way by upgrading the system or part of it .... I chose to use acoustic controls and treatment because it is powerful and cost me peanuts....I dont need to upgrade my 500 bucks system at all and no system at any cost, most better than mine, can induce now the urge to do so for me, so powerful is Helmholtz mechanical equalization of the speakers/room (acoustic controls) ...
Anyway all systems at any cost, unbeknownst to most, are acoustically limited by the room where they are and the lack of control....
I will not speak here about the 2 others embeddings controls (mechanical and electrical) because so powerful they are, they are less impactful than acoustic....Anyway they are all important....
This is a fact.....And my experience....
By the way acousticians NEVER blindfold themselves and use their ears whatever their age after cleaning it for sure ....I imitate them... 😊
My best to you.....
