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.

Has there ever been the assumption that a photo or painting could be mistaken for the real thing? Does that make it any less beautiful? Why should audio be any different?

Sometimes they all bring our a beauty that was hidden even when we saw the real thing.
@ Cdc, short answer, no and no. But who has ever mistaken a photo or a painting as the real thing? The goal of stereo reproduction is fundamentally different in that regard.
Tholt, I agree that for many, the fundamental goal of stereo reproduction is the illusion of the real thing. Not so for photographers. Maybe they are saving themelves a whole bunch of grief not trying to chase down the impossible.

Let's start at the beginning. Are there any recordings that truly sound real? Maybe the best one can hope for is perfect reproduction of what is on the original recording. Because even those are an artistic interpretation by the recording studio, just like a photograph. For example, mic placement can hugely alter how an event is sounds.

So where did this goal come from? Stereophile and the other mag's propagate this so people spend more money trying to achieve what is, dare I say, unachievable. Was this always the goal of hi-end audio? Even back in the 60's when it was considered a main stream, legitimate endeavor by society.
Fact is, when you insert even one wire into the chain, you have irreversibly altered the signal so it is not real anymore.

So when you have the illusion of the real thing in your living room is the stereo creating the illusion or is the listener deceiving himself? Sometimes on first listen and for short periods of time, reproduced audio can be mistaken for the real thing. The classic case is the audio reviewer whose wife calls in from the other room and says it sounds real. Sure, brief non-critical listening. It can happen.

The longer I listen, the more the pieces of phoniness start to make themselves known. In any system. Maybe that's why people keep changing their stereo over and over. The more you listen, the more you hear the defects and thinks by change, they will go away. They do until the new shortcoming pop up. Yes, you can upgrade and the problems are less, but they are never going to go away completely. So where do you stop the madness?

I talked to this one guy who started with Epos and made the rounds for 5 years with many different speakers. I asked him how he compared what he had now to the Epos - balancing out pros an cons - in HIS particular situation. He paused, thought about it, and admitted he really had just been going in circles and had really accomplished nothing. It's all about the journey, I guess.

I see folks getting so into the trees they don't see the forest. For example, John Marks in October 2010 Stereophile who upgrades to Cardas wire and notices the sound is clearer with more bass. But what about the overall perspective that, say, their system with a passive x-over is fundamentally flawed and they are only "polishing a turd"?

Cdc - You raise interesting and provocative questions, but I'm not sure exactly what point of view you are expressing. It sounds like you are saying that, since recordings are themselves "interpretations" of musical events, accuracy in playback is not especially important, particularly for those who value beauty above other things.

My own view is that accuracy and beauty are related in the following way: As system accuracy increases, the beauty you hear is the beauty of the RECORDING, rather than the beauty of the SYSTEM. It may seem inconsequential whether the beauty you hear comes from the recording or the system. But I believe it's important, for the following reason: The beauty of a system is largely CONSTANT, whereas the beauty of recordings is infinitely VARIABLE. To illustrate with your analogy...

As you point out, a photograph is an "interpretation" of an event, in the sense that the characteristics of the photograph - color, contrast ratio, depth of field, etc. - are not identical to the characteristics of the event that the photograph represents. It may be tempting to conclude from this that the presentation of that photograph – i.e. its display for viewing – might as well be an "interpretation" that maximizes the beauty of the photographs. So you decide, for example, to display a group of photographs under a pleasing golden light. By doing do, you may increase the CONSISTENCY of the beauty in the photographs (to those who find golden light beautiful), but you decrease the VARIETY of beauty among the photographs (assuming the photos are color). By giving the photographs a uniform yellow tint, you have reduced their visual diversity, and therefore reduced the variety of beauty in their presentation. A more ACCURATE presentation – i.e. uniform white light, white walls, etc. – would provide greater visual diversity, and therefore greater opportunity for variety in the beauty of the photographs. This highlights the value of accuracy even for those who value beauty above all else: Increasing the accuracy of the presentation increases the VARIETY of the beauty presented.

In my view, the situation with musical playback is precisely the same. As you point out, a recording is an “interpretation” of a musical event, in the sense that the characteristics of the recording – dynamic range, frequency response, transient response, etc. – are not identical to the characteristics of the event that the recording represents. It may be tempting to conclude from this that the presentation of the recording – i.e. its playback – might as well be an "interpretation" that maximizes the beauty of the recordings. So you decide, for example, to use an amp that provides pleasing harmonic distortion. By doing so, you may increase the CONSISTENCY of the beauty in the recordings played back in the system, but you decrease the VARIETY of beauty among the recordings. By giving the recordings a uniform harmonic signature, you have reduced their sonic diversity, and therefore reduced the variety of beauty in their presentation. A more ACCURATE presentation – i.e. lower in colorations – would provide greater sonic diversity, and therefore greater opportunity for variety in the beauty of the recordings. This highlights the value of accuracy, even for those who value beauty above all else: Increasing the accuracy of the presentation increases the VARIETY of the beauty presented.

For this reason, I don’t believe that the fact that a recording is an “interpretation” of a musical event supports the conclusion that accuracy is irrelevant for those who value beauty above other things. Even for people who value beauty above all else, accuracy is an important consideration, because it provides the opportunity to experience a greater variety of beauty.

I agree with you. Just because a recording is not perfectly accurate does not mean you should throw the whole accuracy thing away. Just giving a different perspective that the best you can hope for is a perfect reproduction of the recording, not to reproduce the live event. The way most recordings I listen to sound, no need for me to go much beyond what I have now.

So some of my points are:
1) If we all want perfect accuracy, then if one stereo had perfect accuracy in all regards, we'd all own the same stereo.

2) I think a lot of hi-end audio is about making a mountain out of a molehill to justify hanging a huge price tag on it.

3) People get so hung up on comparing component A to B, trying to hear the smallest of nuances, that they lose site of the big picture of how close is ANY of it to reality.
How about big picture reasoning that, for example, you could spend $10,000 for wire, etc. on a passive system when you'd be better off spending the $10,000 to go active. Or going with a dipole speaker like Linkwitz Orions vs. a monkey coffin?

The photography analogy is relevant because they are going for the same thing as audiophiles except it is visual and so less abstract. It's a different perspective of the same concept. If we could see sound, it would be like the photography people. Maybe a whole lot less disagreements too. Are photography chat sites as debated as audio? Probably not as it's easier to understand and you can decide for yourself. But with audio, being so abstract, we need each other's help to figure the whole mess out. Makes for good socializing though.

Can Albert Porter explain the photography thing for us? I'm sure a lot of people spend big money on cameras too in the name of accuracy stuff like depth of field, sharp focus, correct colors. But why then is that okay, while an expensive stereo is crazy?
