Exactly how do you determine neutrality? Are you using recordings where you were present in the studio when they were recorded? Or is neutrality a code word that justifies a purchasing decision?
Im not real bright but always thought it was an objective term.
Hm ... how do you determine something is neutral? I think it's a matter of listening a "component" with other associated equipment and different recordings. If the sound is consistently neutral, then it is most likely neutral.
As for being objective, since it is always subjected to a person judgement, I think there is always some part of it that is subjective.
We are getting too philosophical here. I don't know how to define what "neutrality" is but I know it when I hear it. That's all I could say.
