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.

I don't think it's a silly term when applied in this way. I suppose you could think of alternate silly terms -- clean, unobtrusive, honest, flat. Neutrality in this application isn't referring to making things sound more distinct, but that things sound more distinct because of the lack of signature (neutrality) of the component(s) producing them.

Way cool discussion going on here. Had a feeling this one would grow legs. If Almarg has summarized the OP's proposal succinctly and accurately --

1)A significant degree of correlation (although certainly not a perfect correlation) can be expected between listener satisfaction and lack of coloration/increased transparency/neutrality/accuracy or whatever such term may be preferred. And,

2)If a component change, or a change to the entire system, results in consistently increased differentiation of the sounds of different recordings, there is a good likelihood that "lack of coloration/increased transparency/neutrality/accuracy or whatever such term may be preferred" has been improved. Meaning, per item 1, that listener satisfaction stands a good chance of having been improved as well.

My question is, how is there a necessary correlation between neutrality, as defined herein, and listener satisfaction? I submit part of the love affair with tubes is their added 'warmth' -- hardly neutral. Apologies to all here if this has been brought up or discussed, I didn't have time to read this entire thread -- damn boss keeps coming over.

@ 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.
