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.

Dgarretson – Hilarious post. And informative.

It is apparent that there is already disagreement even between the three of you on exactly what is a "coloration" and what is not. Though these differences may be minimized some by further discussion, I don't think they can be eliminated. So going back to your definition of "neutrality" as the absence of coloration, if there can be no consensus on "coloration," there cannot be on "neutrality," either.

This is the issue of CATEGORY MEMBERSHIP, in that it raises the question: Just what things fall into the category of ‘coloration’ and what do not? It is a valid question, and any effort to refine our understanding of neutrality must address it. I have proposed a definition of 'coloration' that gives some minimal guidance as to its category members:

(1) They are additions or subtractions to the playback chain.

I should probably have included ‘alterations,’ so I will include it now:

(1b) They are additions, subtractions, or alterations to the playback chain.

And:

(2) They conceal or corrupt (as opposed to eliminate) information about the music.

Admittedly, this is a very broad category. I do not think that its broadness diminishes its validity, however, so long as we find STRUCTURE within the category, in the form of SUBSETS, i.e., TYPES of coloration (or, using the language of a previous post, LOWER-ORDER categories). The more structure we find within the category of ‘coloration,’ the more useful it becomes, and the more guidance we will have to make judgments about CATEGORY MEMBERSHIP. I tried to begin the process of finding structure within the category in my first post on 12/9.

It is worth pointing out that many, many categories have ambiguity and/or disagreement about category membership, including some scientific categories like ‘life’ (Is a virus alive?) and ‘planet’ (Is Pluto a planet?).

It is also worth pointing out that concepts, in the sense of mental representations of categories, are never identical from person to person. There is abundant evidence from cognitive psychology that shows that significant differences exist across individuals’ conceptualizations of all categories. For example, my conceptualization of the category ‘dog’ is similar but not identical to yours, because each of our conceptualizations is shaped by our experience with specific breeds (exposure effects), what dogs we’ve seen recently (recency effects), and a host of other variables. What this means is that there is NO SINGLE CONCEPT of ‘dog.’ There are many overlapping conceptualizations of ‘dog.’ Two things follow from this.

The first is that the disagreement among me, Cbw, and Dgarretson about the conceptualization of ‘coloration’ is to be expected, because IT IS TRUE OF ALL CONCEPTS. But that does not make the category 'coloration' useless any more than diverse conceptualizations of ‘dog’ make that category useless. Whether or not the differences among our various conceptualizations of 'coloration' can be minimized through discussion and debate is yet to be seen. In the meantime, I think Cbw's approach is the right one:

When Bryon talks about playback system coloration, I just substitute "playback system distortion" because I know that is the way he is using the term. If I come to believe that my understanding of the term is non-standard, I'll adjust my thinking accordingly. If I become convinced that I'm right, I'll suggest to Bryon that he adjust his terminology.

Second, the existence of diverse conceptualizations of ‘coloration’ highlights the need to STIPULATE a definition for the purposes of conversation. The stipulated definition is subject to error, ambiguity, vagueness, debate, and revision, but it is a necessary step in the discussion and development of ideas. The value of a stipulated definition should be judged by its ability to further investigation. In that sense, it is a HEURISTIC. Heuristics are sometimes messy, confusing, and frustrating, but they are the mainstay of the exploration of ideas.
Very interesting posts, indeed. Cbw, I did not mean to suggest that complete agreement on terms is necessary - certainly all of these terms are inexact. And you are correct that the vast majority of musicians are very comfortable with shades of grey and non-absolutist thinking. Almost none would call themselves "objectivists" as Dgarrestson has so well defined the perspective (however, very few would also say that they would be completely "subjectivists", either, though they would lean much more in that direction). This is a large part of the reason that the concept of "neutrality" does not have any appeal even as an idea to me and many others. I was speaking more of agreement on colorations when listening to a system, not when defining types of colorations. As you say, there is room for general agreement in defining certain types - I think the disagreement could come even over whether you were hearing them or not, and certainly over whether they were desirable or not.

Dgarretson, hilarious opening of your post! And we are in agreement about subjectivists and objectivists using much of each other's methods. As I said, your approach is very close to the one I suggested. And they do indeed share the same hubris/foibles. I also think you are correct on any desirable colorations also being accompanied by undesirable ones. There are always trade-offs, I think.

I would like to point out a connection to something Dgarretson said, and something Bryon said in their latest posts. Dgarretson speaks of "my idea of professed subjectivists and objectivists whose different aesthetics may each progress toward separate but valid senses of neutrality defined in the broadest sense." Bryon speaks in his last paragraph of stipulating definitions, and calls this "heuristic." I had not encountered that term in long time, and will admit having to look it up. Bryon is using it in the sense of the first definition in my unabridged dictionary, which reads very close to his explanation in his post. I was struck by the second definition, however, which is "encouraging a person to learn, discover, understand, or solve problems ON HIS OR HER OWN, as by experimenting, evaluating possible answers or solutions, or by trial and error." My emphasis, and I would also emphasize the plurals - answers and solutions.

It seems to me that Dgarretson's comment implies that there is more than one valid "neutrality." Perhaps this was not your intention, but it seems to me that here you are really talking about a "personal reference point," a phrase I used earlier on in this discussion. Likewise, Bryon, I think that although it may be possible to come up with a very lengthy list of different categories of colorations that many audiophiles could agree upon IN THEORY, I doubt that there would ever be much consensus on this IN PRACTICE, the result being that very few audiophiles would end up coming up with the same sense of "neutrality." Everyone's hearing is different, and their sonic priorities will be different as well. I think your approach ultimately is only useful for each individual on his or her own, to come up with his or her own "personal reference point." I don't think there could ever be a generally accepted sense of "neutrality," even as you have refined it with the different types of colorations.

I'd like to point out that the title of this thread is "How do YOU judge YOUR SYSTEM'S neutrality?" [Emphasis mine.] It is not, "I'm going to compel you to make your system conform to my idea of neutrality." It seems an obvious point, but it appears to have been lost in much of the discussion throughout this thread.

I disagree. My own experience with my system leads me to believe that if you could A/B the various types of coloration in an otherwise constant system, almost all audiophiles would prefer the more neutral system. Maybe Dgarretson or Almarg could tell us if such a test is possible on some of the forms of coloration (for instance, is there a way you could introduce and remove intermodulation distortion, harmonic distortion, crosstalk, etc.?), but how many audiophiles are going to prefer a boomy speaker cabinet, room modes, comb filtering, etc.? I had the opportunity to listen to reduced jitter in my system in two stages (first my adding a Monarchy box between my computer and DAC, then going with a DAC with asynchronous USB), and with each improvement, there we significant improvements in sound quality that I can't imagine any audiophile not preferring. I liked my sound before, but after reducing this form of coloration, I can not imagine going back.

I think personal preference plays its strongest role when tradeoffs are required. For instance, if one has to choose between an excess of speaker cabinet resonance, or having poorer resolution, it is likely that audiophiles would be split. But the choice between more or less cabinet resonance is simple, and I think most audiophiles would choose less.

I'm not so sure. Cabinet might resonate with the floor at the lowest bass notes that otherwise would not be audible. I know myself people who like it. Some people like "punch" in the midbass that again cabinet resonance might bring.

Many reviews of Benchmark DAC1 mentioned that sound might appear lifeless (too clean) without all the jitter introduced noise and that was exactly my first impression. Many people call Benchmark lifeless, analytical or sterile. When you add a little THD it becomes "lively" (like fuzz guitar compare to clean jazz guitar).

Personal preference is what it is - personal and very subjective and there is also no reference point/baseline. In addition all colorations affect each other.
i have many things to say. first, many of the preceding comments seem rather academic and superfluous. one of the purposes of listening to music is to enjoy it. thus it may not be necessary to analyze it (a stereo system to the extent indicated)in any way.

secondly, one cannot assume what forms of coloration are prefereable or not orefereable. i may prefer a boomy cabinet and be in the minority of serious listeners.

in the third case the term "audiophile" has been used many times but has not been defined. i suspect that i am not an audiophile and am not subject to the aforementioned stipulations. i may be the exception to the "rule".

finally, KISS. some of the analysis seems unnecessary and perhaps the term "serious listener" should substitute for "audiophile". after all, without defining the term the conclusions are obvious.

although the theme has generated many posts, it would seem that points have been made and that further discusssion may not add value to what has already been said.

i am not and never will consider myself an audiophile, as my pursuit is the enjoyment of music , rather than an analysis of stereo systems.

the neutrality of stereo systems theme should be the basis for a debate in an academic institution.
