neutrality & transparency: what's the difference ?

Current?

"My best friend's sister's boyfriend's cousin said she saw Ferris pass out at 31 Flavors..."

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

in fact they are not.

I have not found many people who believe that. In fact as Jamscience mentioned, one is not event he subset of the other. From the Stereophile Glossary:

neutral - Free from coloration.

transparency, transparent - 1) A quality of sound reproduction that gives the impression of listening through the system to the original sounds, rather than to a pair of loudspeakers. 2) Freedom from veiling, texturing, or any other quality, which tends to obscure the signal. A quality of crystalline clarity.

In my opinion and somewhat based on the above definition, "neutral" is a term that mainly applies to the frequency response of a component, i.e. there are no colorations over the proposed range of the component. Bass extension does not play a role in my opinion though, e.g. many Monitor speakers are considered neutral in their respective range.

"Transparent" on the other hand does not necessarily only make a statement about frequency response, but also affects attributes like timing, rise times, ringing, and most importantly in agreement with part 1) of the Stereophile definition, spatial clues and information.

At the end of the day, it would be nice to have an agreed on Glossary. The main problem here is though semantics: Using subjective, metaphorical terms to gain an objective description is bound to fail.

by neutrality, i mean accurate or the truth. if the input doesn't equal the output, there is inaccuracy, error hence not accurate not neutral.

transparency is a window on the music, if a component(s) is restricted in frequency response, and a source is also restricted in frequency response , i.e., within the range of the equipment, the result is transparency. you hear what is on the recording.

if there is some veiling, but very slight, you may still hear everything on the recording. however, in this case the result is less clear the the recording, hence not the truth, not neutrality, not accurate, but possibly transparent enough to be assigned the term

since perfection does not exist, there is no absolute transparency there is inaccuracy.

however, for listening purposes, audibility, one acknowledges imperfection and still uses the term transparency.

i still maintain that if a stereo system/compent is virtually neutral, transparency is implied.

if a stereo system is virtually transparent, virtual neutrality may or may not exist.

the attribute of virtual neutrality is more rigorous in its requirements than that of virtual transparency

I would argue the other way. Use photography as an analogy. If you enlarge a photo and the color balance of the enlargement is identical, then the process is neutral. That is, no colors are highlighted or muted (a stereo system is basically a signal enlarger). If the enlargement is blurred or distorted, then the process is not transparent - the lens could be low quality, defective or dirty. But it still may be neutral, and you may not discern it because of the distortion. Transparency is needed to see neutrality, IMO.

Gs5556, good analogy. I guess the definition of "Neutral" in photography with respect to the color spectrum seems to agree with the definition in audio for frequency response. To my knowledge this is the usual meaning and the definition of neutral in general.

Mrtennis, you interpretation of the term "Neutral" does in my opinion not agree with the generally accepted definition, and is rather based on your own subjective interpretation of the word. If you can find a good reference that defines the term Neutral in your way, please let me know: To MY knowledge the term Neutral is a very precise term and refers to the flatness of the frequency response only. The term you like to introduce would be more "Accuracy" to the source/truth etc. "Neutral" could be defined as a subset of "Accurat".

Again from the Stereophile Glossary:

accuracy - The degree to which the output signal from a component or system is perceived as replicating the sonic qualities of its input signal. An accurate device reproduces what is on the recording, which may or may not be an accurate representation of the original sound.

Maybe this helps to clarify the use of terms.

Best wishes,
