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.

Very interesting discussions, guys! Bryon, I think you do misunderstand my position after all. Basically, I do not believe that "neutrality" can possibly exist at all, whether we are talking about a single piece of equipment, the entire system as per your definition, or in live music; and, as Kijanki says, I seriously doubt anyone would think it a virtue if it did. I am not trying to make the perfect the enemy of the good - I don't believe there is a perfect.

Some other thoughts - Bryon wrote "The success of room correction relies on the technology involved and how it is implemented." This completely ignores the human ears setting up and/or listening to the result of the technology (not to mention the designer of the technology). The dealer who set up one room correction system I heard clearly thought he had done everything correctly, and he thought the result sounded just fine, yet the result sounded awful to most he played it for, worse than before the correction. I have heard others that made a huge positive difference.

As far as Bryon's characteristics of a good playback system vs. characteristics of good musical playback, I completely agree that these are not the same thing. Every playback system is different, and two completely different systems can both result in good musical playback. This seems obvious. Where we differ is I don't think either has anything to do with "neutrality."

Bryon wrote "A neutral room will make it easier to achieve a neutral system." There is no such thing as a neutral room. As I said in a previous post, the closest thing might be a recording studio. But the purpose of recording studios is NOT to make things somehow "neutral." In fact, as I said before, it is for the exact opposite purpose - removing as many characteristics of the room noise as possible allows the sound engineer as much leeway as possible to create the sound that he wants - to create the sound color of the engineer's personal choice. This also goes along with what I said before about designers of audio equipment - they are not striving for some sort of "neutrality." They are aiming at their personal ideal of what the sound should be.

Bryon wrote "It seems to me that the value of an audiophile developing expert perception of the playback of recorded music is self-evident." Again, I don't think there is any disagreement here. The disagreement is over whether "neutrality" has anything to do with it.

The bottom line here (going back to the OP) is that many of us feel that just because you change one piece of equipment in the system, making 1) individual pieces of music sound more unique, and 2) your music collection sound more diverse, this does not mean you have operationalized the term neutrality. It just means you have a better sounding system.

Let me give you an example, again going back to the OP. Assume a room with good qualities for music playback, and assume a very high quality music playback system (which this room is of course part of). Now, let us say you replace very high quality preamp A with very high quality preamp B, keeping everything else the same. How will you know which one is more "neutral"? I submit that you can't. But you can know which one makes the system sound better to you. And I would also guess that 100 audiophiles that listened to this comparison would probably split close to 50/50 on which one did sound better, and that there would be many different reasons why each made his choice. This is what Kijanki is driving at when he says "how do you know how it is supposed to sound?" There is no one answer to this question, which is where I think your "neutrality" concept/operationalization falls apart, despite your VERY good arguments - it requires that there is ultimately one answer. But thankfully, there is no black and white in music or music playback.
How do you know how it supposed to sound? Sitar from Northern India sounds completely different than Sitar from southern India. How do you know?

Bryon wrote: "By having heard one."

That's the problem - by having heard one where? In small humid room or big concert hall. What brand of Sitar?

As for neutrality being a virtue - Do you think that person who likes more bass than neutral should force himself to listen at home the way he doesn't like (neutral). If I cannot hear treble as well as when I was young - am I allowed to get brighter system. Overall result might be neutral but to who's standard (since I cannot hear treble in live performance). Whole issue is very foggy. I can only say what sounds good to me. As Learsfool mentioned sound of instrument in sound-dead studio is colored by recording engineer (therefore not neutral). Why do I have to adhere to this. Some instruments like cello have very complicated radiating pattern (only backwards at 300Hz I think). Can you imagine what mess recording engineer can make here. At the concert sound is far from perfect and different each time. Open air concert is way different than small auditorium etc.
I think you hit a homer there, Kijanki. Hearing is an issue. I know a reviewer who has a high frequency deficiency. Music that is loud and dynamic is a good thing. Accuracy is not. Amazingly, my hearing is very good. I want sound at it's proper levels still.

Learsfool - What do you think of Al's comment:

Consider a system purchased at Walmart for a total system price of $300, in comparison with say a $50K system such as some Audiogoner's have. I don't think anyone here will disagree as to which one will provide better and more enjoyable sound, and I don't think that anyone here will disagree as to which one is more neutral/accurate/etc.

Do you not believe that a $50K system is more neutral than a $300 Walmart system? And conversely, do you not believe that the $300 system has more coloration?

It is important to note that the last two questions must be answered the same way. That is to say, if you do not believe in neutrality, then YOU DO NOT BELIEVE IN COLORATION. That is because neutrality has been defined on this thread as the (degree of) ABSENCE OF COLORATION.

Colorations are additions or subtractions to the playback chain that conceal or corrupt information about the music. If you believe that coloration does not exist, then what is intermodulation distortion? What is the resonance of a speaker cabinet? What is crosstalk? In my view, they are additions to the playback chain that conceal and corrupt information about the music. That is to say, they are colorations. And if colorations exist, then neutrality, defined as the (degree of) absence of coloration, exists.

Learsfool wrote:

If you believe this, then you believe that there is no such thing as ROOM COLORATION. Then what is a room mode? What is flutter echo? What is comb filtering? In my view, they are additions and subtractions to the playback chain that conceal and corrupt information about the music. That is to say, they are colorations. And if colorations exist, then neutrality exists.

I was not ignoring the human element. I meant that to be part of “implementation.” ‘Implementation’ can refer to the PHYSICAL DEVICES that perform some function or the ACT of performing some function, presumably by a person. I meant for both to be included.

One of the advantages to my operationalization of ‘neutrality’ is that forming judgments about neutrality does not require us to be able to arrive at a consensus about which is the better component in an A/B test, which as you point out, is often difficult and sometimes impossible. It only requires us to arrive at a consensus about which component makes individual pieces of music sound more unique and a collection of music more diverse. Perhaps that would be a difficult consensus to achieve as well, but I suspect it is far more realizable than getting audiophiles to agree on which component is "better" in any given A/B test.

And if a consensus were reached about which component was more neutral in an A/B test, it does not follow that the more neutral component is the "better" component, since there are other sonic virtues that are, and should be, considered when evaluating components.

Yes. That is what it means to be an Objectivist.

You are allowed to do as you like. It is not for me to tell anyone how to listen to music. I think if you were to read my posts on this thread you would not find a single comment suggesting that someone else SHOULD listen in a certain way. I have, however, made arguments about the value of neutrality. This may seem like a contradiction, but it is not. That is because, while I am an Objectivist about neutrality, resolution, and accuracy, I am a Subjectivist about audiophile values. I do not believe that there is one "right" way to listen, but I do believe that there are more neutral, resolving, and accurate ways to listen.

As far as your comment about compensating for your high frequency hearing loss with a brighter system, the issue there is exactly analogous to the use of EQ in a system to compensate for room effects. In a previous post, I wrote:

[The] question is whether the use of EQ is NECESSARILY a deviation from neutrality. The answer is: It depends on which level of organization you are talking about. By definition, the use of EQ is a deviation from neutrality AT THE LEVEL OF THE COMPONENT. But it is not necessarily a deviation from neutrality AT THE LEVEL OF THE SYSTEM, where "the system" includes the room and your listening position in it. That is because the judicious use of EQ could compensate for room effects that are themselves deviations from neutrality. For example, if the room contains a lot of hard surfaces and is bright, EQ’ing the treble could result in a SYSTEM that is more neutral, even though, at the component level, you have made the signal less neutral.

Analogously, in the case of compensating for your high frequency hearing loss with a brighter system, I would say: That "compensation" is itself an attempt to achieve a measure of neutrality in the system, by removing the midrange and bass "coloration" created by your loss of high frequencies. But in your case, "the system" no longer stops at your ears - it INCLUDES your ears, along with the details of your hearing loss.
Bryon wrote: "I do not believe that there is one "right" way to listen, but I do believe that there are more neutral, resolving, and accurate ways to listen."

And I do believe that there is "perfect" woman out there but I'm not interested.

It is very subjective. I can always find somebody who will like sound of your Walmart system more (and call it more neutral/natural sounding). There is a few reasons for that. Some say clear=sterile and resolution=analytic. I read opinion that instruments should not sound separately but together. Some people don't like strong dynamics. There is no right or wrong here. Listener is a part of the system as room is and there is no escape from that. Who will be the judge? The proper question is not whether it sounds neutral (how to know that?) but rather if sound is pleasant, involving etc.
Can musical presentation that is "uninvolving" be more neutral? Presentation can often be converted to involving one by spicing frequency extremes or adding a little bit of distortion. My Benchmark DAC1 was praised by studio engineers and often called by people sterile and uninvolving. Studio engineers made once experiment in the studio recording guitar live and playing thru different DACs (similar price range). Benchmark was the most accurate but people liked other DACs more.

Defining neutrality reminds me TV discussion on the subject of "good taste" where serious people tried to define it (it does not exist).
