How do you judge your system's neutrality?



Here’s an answer I’ve been kicking around: Your system is becoming more neutral whenever you change a system element (component, cable, room treatment, etc.) and you get the following results:

(1) Individual pieces of music sound more unique.
(2) Your music collection sounds more diverse.

This theory occurred to me one day when I changed amps and noticed that the timbres of instruments were suddenly more distinct from one another. With the old amp, all instruments seemed to have a common harmonic element (the signature of the amp?!). With the new amp, individual instrument timbres sounded more unique and the range of instrument timbres sounded more diverse. I went on to notice that whole songs (and even whole albums) sounded more unique, and that my music collection, taken as a whole, sounded more diverse.

That led me to the following idea: If, after changing a system element, (1) individual pieces of music sound more unique, and (2) your music collection sounds more diverse, then your system is contributing less of its own signature to the music. And less signature means more neutral.

Thoughts?

P.S. This is only a way of judging the relative neutrality of a system. Judging the absolute neutrality of a system is a philosophical question for another day.

P.P.S. I don’t believe a system’s signature can be reduced to zero. But it doesn’t follow from that that differences in neutrality do not exist.

P.P.P.S. I’m not suggesting that neutrality is the most important goal in building an audio system, but in my experience, the changes that have resulted in greater neutrality (using the standard above) have also been the changes that resulted in more musical enjoyment.

Cbw723, if you go back and reread the entire thread, you will see that not just myself but at least three others are indeed questioning the very concept and/or definition and/or operationalization of the term "neutrality", with reference not just to live music, but also within the context of an audio system. We have not all questioned the same aspects exactly, but all of this has indeed been under debate at some point in the thread. My position is/has been that this "neutrality" does not and cannot exist, and I have spoken of it at length.

The term "coloration," on the other hand, I don't have quite as much of a problem with, though Newbee is probably correct that I am using the term too broadly (as opposed to Bryon's too narrow usage). My position is that there is no such thing as an absence of "coloration" in music and/or music playback and/or an audio component; therefore Bryon's "neutrality" couldn't ever actually exist, even as he defines these terms. Hence, his operationalization of the term is of no real practical value (especially since no one has yet been able to describe what it would sound like, despite this one ultimate sound goal being "what it means to be an objectivist," according to Bryon).

I fully realize, Al, that the term "neutrality" (and the substitutes you mention) is in wide use more or less as Bryon uses it. That fact doesn't make the usage correct, though, and many of us obviously get along fine without it - in a different thread some time ago it was my nomination for the most useless term in audio, where it got the most early agreement, if I remember correctly, but I haven't looked back at that thread in a long time. I agree with Newbee that there is no way one could reword the proposal "to allow convergence," and I like what he had to say in closing. If Bryon or anyone else changes a piece of equipment in his system, and he likes the resulting change in sound better, that's great! That is a goal of all of us audiophiles. I submit that "neutrality" does not have anything to do with it. In my view, Bryon has yet to propose any condition that indicates the presence of a characteristic of "neutrality" at all, let alone "reliably." He has mentioned a few different types of distortion, all of which have a technical explanation not requiring the existence of "neutrality," and he has spoken of absence of "coloration," which I have already spoken of at length.

Bryon, those are good examples of definition in relation to absence, thanks! However, I am compelled to point out that all of those things you list have been proven to exist - your "neutrality" is much more elusive. Another part of my problem with your terms is that I cannot accept your use of the term "coloration" as a purely negative term, something always to be removed. My previous post spoke at length of the relationship of music and color. A designer of a piece of equipment has a specific sound color he is aiming at, that is different from all other designs/models out there, otherwise why design another piece of equipment? "Neutrality" simply is not a goal of design (for a start, that would require knowing what "neutrality" sounded like). Let me refer again to my two high-end preamps within the same exact system example. How could you tell which of them was more "neutral?" I submit you couldn't, and therefore, your operationalization of the term does not have any real practical value for audiophiles, as Kijanki keeps pointing out.

What does have value in this example is to try to figure out why YOU like the sound of one better than the sound of the other - for example perhaps you conclude that preamp B has a very slightly warmer midrange, and your favorite female jazz vocalist recordings are more enjoyable in consequence. You may even discover a technical reason for this specific sonic color difference from preamp A. This could be a real help/guide to improving the sound of your system overall. But how could you tell if it was therefore more or less "neutral?" You couldn't. Nor would there necessarily be agreement among any given group of people that this difference was an improvement. But if you think it was, then you can use that information to improve the sound of your system to your ears, and that is a good thing - that has real value. But only you can really make that call, and therefore determine that value, for yourself, according to your own personal sonic tastes, or "reference point"; I submit that this is what your "neutrality" concept really amounts to, as someone else said near the very beginning of this thread, sorry I don't remember who. To sum up, even given your definition of the terms, a) you could never know what "neutrality" would sound like, because there is no one single "correct," "perfect," "absolute," "neutral" sound; and b) there will never be "convergence" on exactly what is a "coloration," either. I submit that both a) and b) are good things, not bad; that is why we have so much great variety in high end audio reproduction. Just continue your search for components that improve the sound of your system and your music collection to your ears - it really is that simple. The harder thing is to work on improving your ear - that takes constant and diligent work and practice, but I guarantee it would (hopefully will) lead to much greater enjoyment of your music and your system (including your ability to judge differences between pieces of equipment) then your search for "neutrality" ever has or will. Whatever path you choose, I wish you continued success in improving your enjoyment of the music! That is what really matters to all of us!

If one's goal is less system coloration to increase the likelihood that the colorations that were present in the original performance will be reproduced accurately, then precisely knowing what a recording is supposed to sound like is of utmost relevance. Without the baseline of knowing what a recording is supposed to sound like, one cannot judge the degree of coloration in a system.

Tvad is taking up the contention, made by Learsfool and Kijanki, that in order to judge the coloration/neutrality of a system, you must know what the recording is “supposed to sound like." Learsfool and Kijanki have used that contention as the first premise of the following argument:

(i) If you are to judge the coloration/neutrality of a system, you must know what the recording is supposed to sound like.
(ii) You cannot know what the recording is supposed to sound like.
(iii) Therefore, you cannot judge the coloration/neutrality of a system.

The reasoning of this argument is valid. But, in my view, the argument is unsound, because it contains a FALSE PREMISE, namely, premise (i), that the ONLY way to judge the coloration/neutrality of a system is to know what the recording is "supposed to sound like." That premise is false, I believe, because there is ANOTHER way to judge the coloration/neutrality of a system, namely:

(1) Individual pieces of music sound more unique.
(2) Your music collection sounds more diverse.

In other words, my operationalization of neutralty is a method for judging the coloration/neutrality of a system that DOES NOT REQUIRE YOU TO KNOW WHAT THE RECORDING IS SUPPOSED TO SOUND LIKE. It only requires you to make judgments about changes in CONTRAST or DIFFERENTIATION.

Admittedly, my operationalization is only a way to judge the RELATIVE level of coloration/neutrality of a system, not its ABSOLUTE level of coloration/neutrality. But this is still valuable to the average audiophile, since he must make relative judgments all the time, such as, when changing components. And the fact that my operationalization of neutrality enables the audiophile to make (relative) judgments about coloration/neutrality without knowing what the recording is "supposed to sound like" is what makes the operationalization so actionable.

I believe that this also sheds some light on the disagreement between Learsfool, Kijanki, and Tvad (L/K/T) on the one hand, and me, Al, and Cbw (B/A/C) on ther other, concerning the RELEVANCE of premise (ii), that you cannot know what the recording is supposed to sound like. For L/K/T, premise (ii) is essential to the discussion, because of their belief that knowing what a recording is "supposed to sound like" is the ONLY way to judge the coloration/neutrality of a system. For B/A/C, premise (ii) seems irrelevant to the discussion, because of their belief that there is another way to judge the coloration/neutrality of a system, namely, the way I proposed in the original post.

Grant (Tvad), Newbee, Learsfool, Kijanki, this is exactly what I was getting at when I asked "why does the fact that it is difficult, in general, to precisely know what anything is supposed to sound like have any relevance in THIS DISCUSSION?" (emphasis added).

As I see it, Bryon has simply proposed a methodology or tool (I prefer those terms to "operationalization of neutrality" because they are easier for me to understand :)), which can be a useful addition to the arsenal of other methodologies (both subjective and objective) that we use to work toward the goal of more enjoyable listening. As I see it, it's as simple as that.

Al, I'm glad to see that I'm not the only one who has difficulty with Bryon's 'operationalization of neutrality' used as a description of how to judge the sound of a system.

Perhaps I'm just exposing my ignorance, but I might be less resistive if Bryon, or anyone, could in a brief paragraph explain how one, in actual practice, utilizes this 'methodology', and if possible how this 'tool' or 'methodology' differs substantially from what audiophiles do every day when playing with their toys without placing a title on the process, i.e. as I described in the last paragraph of my last post.
