My answer to above question is as follows.
Nice question!
Good audio system shall have all the thngs you mentioned.
But in reality, it is not posseible.
About 3 weeks ago, I visited Mike's Lavigne's listing room.
His well respected system has almost all of the qualities but not perfect.
But fortunately after listening to his nice system, I still could enjoy my system with tube pre and amp which give more of soundstage depth and holographic imaging.
If I grade his system and my system from my point of view.
Tonality -
Mike's A* all clean no sibilants due to top grade source of turntable and Wadax the best digital available now
It gave the best tonal purity that I had ever listened.
I do not play vinyl and only digital.
Aurender N30sa, Chord Dave modified with three Farad LPS and Mscaler.
My system A- some sibiliant but smoothed by tube pre and power amp.

Due to lot of drivers in Scaena 3.2, my system is also excellent, but Mike's is kind of supreme.

Both Mike's and mine does not emphasize super details but musical.
Soundstage
Mike's Soundstage width A- and depth B+
Mine width A-, depth A
Line array of Sceana 3.2 give excellent soundstage and nice placement of each instrument.
Mike's big speaker need more breathing room than his modest large size room of 19 by 30.
Thus depth is rather average although not flat.
Many people prefer Wilson speakers on soundstage width and depth,
I feel that Wilson speakers over exagerrate them

I do active tri amping.
Pair of Rel 31 and Scaena 18 inch subwoofers tandem below 90 hz
Altec 15inch basshorn from 90 hz to 290hz
Scaena line arrays from 290 hz up.
In the video, Lansche 4.1 and Altec A7 treble horns are idle.
