How do you know when a stereo sounds good?

I think the purposes of the OP’s questions were to see if anybody had an explanation different from "I just feel it and know it." I agree with you that the vast majority of the answers will likely be that one, but that doesn’t mean someone might have a different way of saying it or a different perspective. To you, there’s only one answer and the question was meaningless, but you can’t know ahead of time what the other answers will be. Maybe someone will surprise you with an answer you hadn’t yet considered.

And you still didn't explain the science fiction part of your reply.

First, someone who sell pieces of gear will say: your feeling about yourt system is not enough... You need this piece of gear to increase your experience...The measuruments AND your listening experience would say so...

Second, it is not false to speak like that, but ANY "TWEAKS" must be experimented in a good acoustic settings first... WHY ?

Because many costly tweaks even good one COULD be useless or way less useful in a good acoustic settings...

I sell creativity not products...

Acoustic is the black matter in audio and the elephant in the room....NO TWEAKS in my system could replace my acoustic treatment and controls anyway... Even those i tried and which  worked well... NONE....

Your room acoustic treatments are tweaks. You are modifying the spatial volume of your room or affecting how the sound waves reflect or diffract. Whether you modify signal before the speaker or modify the sound waves after the speaker doesn’t matter. You are still tweaking the sound to suit your own personal belief of the ideal sound. Your ideal of what is good is not necessarily anyone else’s ideal. 
 

If you have to tell people they are believing in magic because you can’t hear what we do, then you need more art in your life. 

Your room acoustic treatments are tweaks.

For sure there exist 2 methods to fine tune the room acoustically: BY EARS or with a MIC and an electronical equalizer...

But ask any acoustician about electronical equalizer... They dont use it generally and if they do it is only a secondary tools...

I use my ears with my timbre recognition BIAS for sure...

But the fact that 2 people EARS and hearing bias are different CANNOT made acoustical principle in Helmholtz method VOID and useless...

Acoustic principles are not "tweaks" they are science.... The way you use them is according to your SPECIFIC EARS for sure...

I use Helmholtz resonators and diffusers grid.... Nothing is a "tweak" here for 2 reason: it cost NOTHING to experiment with that, i used cheap bottles and plumbers tubes...

And "tweaks" is about a particular READY MADE SOLD device, Helmholtz method in acoustic is not a "tweak"...

Tweak are secondary addition to an audio system in the audiophile lingo...

Acoustic is not a secondary addition to an audio system, it is ESSENTIAL and a dedicated room is the more important luxury in audio...
