Questions for specialists on “warmth”

I have heard sound from speakers that are more neutral and detailed in texture and focus the presence of all frequencies, sound that captured air resonance and produced a holographic image, but I doubt that’s what warmth is.

It seems to me that “warmth” is manipulated by engineering.
What is the purpose of “warmth”?
Does it actually exists or is it in imagination, or is it given a phony name (resonating warmer air?) in result I couldn’t link what I heard to “warmth”.

Sorry for the many questions below, without evidence of existence of this “warmth”, I get that feeling somebody is telling me the earth is flat whenever they mention “warmth”.

Maybe it is more psychological, is it then related to the release of a certain type of chemical in the body?

I had thought that maybe warmth means organic. If that’s true, is warmth created with possible ways to give the listener organic illusions? If that’s true, can the sound become too warm that it becomes hot; or too organic that it makes the actually sound we hear in our daily lives in comparison cold, is that good for one’s marriage?

What are the differences between warm and cold, can any expert give some generalization of the technical differences that sets them apart? Are the sound manipulated, how?

How can warmth be created from the play back perspective?
Cable
With what material, why
With what construction, why
Digital
Why and what done in digital processing; AD (analogy to digital) and DA
Speaker
Are they then best to be construction with organic material?
