neutrality & transparency: what's the difference ?

neutral and transparency are often considered the same by some hobbyists.

in fact they are not.

neutrality implies no alteration of the signal, whatsoever.
i have used the term "virtually" neutral to imply no audible coloration. of course this is a subjective term.

transparency is a subset of neutrality. it implies a perfectly clear window on the recording.

let me illustrate. suppose an amplifier has a slight deficiency in bass reproduction, e.g., it cannot reproduce any frequencies below 40 hz. that amplifier would not be considered a neutral component.

if said amp reproduced all "information" on a recroding within its range, i.e., above 40 to whatever, without covering up any detail, it would be a transparent device.

thus transparent includes the pssibility of an error, but also implies the passing of all information within the range or capability of the component.

transparency is a subjective term. often when used it means "virtual" transparency because it is possible a component may be hiding information that one is not aware of, but yet one perceives that no information is missing.

any thoughts ?
