What is a high end stereo SUPPOSED to sound like?

I've been thinking about this for a while....like 10+ years. Would be interested in what others have to say.
My latest answer would have to be "nothing". I want to hear the music and not the stereo. Like "Come over and listen to some music" versus "Come over and listen to my new stereo". If there are errors, they would be errors of omission, not commission because I assume they are less noticeable.
High end is supposed to sound like real live unamplified music- Natural, mostly free of elecronic artifacts on well recorded material.

Instead what we get(99% of time,regardless of price)is tonal freqency balance that is generally 10s to 100s of Hz shifted to the right compared to the real thing, making sound thinner than actually is real life. Also I notice that the timing is off between fundamentals and overtones/undertones. Combine the two and you have unnatural presentation. I don't know why is that. Is it electronic artifacts that you can't avoid or recording can't pick up everything?

Enter,add/subtract your own colors that makes it as close to 'realistic' as possible for YOU.
I will simply reframe the question. What is an EXPENSIVE stereo SUPPOSED to sound like.

Again he didn't ask what a perfect stereo should sound like?
And in my view either expensive or just really good it better make some sounds. Not nothing for sure.
