All of these terms are just "poetic license"! I'd rather look at frequency and pulse response, polar dispersion and power handling. Speakers that measure better will sound better. Unlike electronics speakers haven't evolved to the point where their flaws are hidden from measurements!
Can someone please explain
What you mean when you say (whether it’s a speaker or amp or preamp) it’s darker or warmer or softer or leans to the brighter side of neutral? Are you talking about how ss compares to tubes to class D? Analog to digital? How do you know what "neutral" is? How do you not know it’s actually in the recording?
