You're lack of knowledge of this matter is very evident and you're skepticism and confusion would be very easily cleared if you made an actual honest exploration into hi-fi audio
I'm an EE and have made an honest exploration into this topic many times, and yet still have no explanation of "warmth" beyond the addition of distortion resulting in even-ordered harmonics. Which is precisely a decrease in the SNR from input-to-output.
That might sound good! But it's a less-than-perfect reproduction of the source signal.
If there's a better explanation than what I've come across every time I've search for this, I'm all ears and honestly open to being corrected.
