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.

Vince, you assume listener thinks that his sound is colored. Just ask owner of very warm sounding system (vinyl, tubes, warm speakers) if his system sounds natural (natural sound being effect of neutral system and neutral recording) - I would be very surprised if they'll say that sound is colored.

What is natural sounding to me might be horrible sounding to someone else. Bryon was trying to bring "listening experience" here believing that one can "neutralize" sound he likes by getting more listening experience. I don't think so - just look at my example with critics and class D amps in previous post.

Kijanki, my view is that analytic & sterile err at the opposite extreme of unresolving warmth. Both kinds of extremes are colorations and as such, represent deviations from neutrality. There are many instances in which internal mods to electronics improve resolution while also preserving and even enhancing warmth. A move in this direction is an uncompromising step toward neutrality. Granted there are no absolutes, but as long as a playback system bothers one even a bit with an undesireable coloration, I do not rationalize away the negative coloration as an inevitable compromise. For me the notion of a step toward neutrality is a useful construct to describe resolution of what in the conventional wisdom of audio may appear on the surface to be unreconciliable characteristics. Resolutions of this type may be heard as the system getting out of the way of the music.

Dgarretson - absolutely agree. The problem is who is the judge? My system sounds very resolving and natural to me whilst I'm not sure it would sound the same to you.

You are already "contaminated" believing that warm resolving sound is a goal. Warm sound (enhanced even harmonics) sounds wonderful on voice or guitar but is pretty bad on instruments with harmonic structure more complex than common overtones - like piano or percussion instruments. Piano, according to Benchmark's technical director John Siau can sound on very warm system "out of tune".

Complete neutrality, that is the live performance, cannot be fully attained by the engineers or the playback system. My goal is to bring out the best of what I have on the CD. That is my striving for neutrality.

Color is a fine for others. I know of one major critic of mine that says the more warmth generated into the music the better. He uses the cello as a favorite example. To him, the more voluminous the sound the better. Just load it up with euphonic tubes.

Sterile is another coloration. Real music is never sterile, well, almost never.

Vince, I hope you realize that what sounds neutral to you might sound too warm or too cold to somebody else. I don't question that one might perceive sound as neutral but it is just only personal subjective opinion.

This statement makes warmer equal neutral. In addition there are mentioned "undesirable colorations" or "negative colorations" (oppose to desired colorations or positive colorations)

If there is a proof that neutral is subjective this is it.
