[rec.audio.high-end] Clean Car Syndrome

	Thoughts on high-end listening, by Allen Watson III:

The recent spate of comments about green-lining and sound rings and
such got me to thinking about the Clean Car Syndrome, or Why It Sounds
Better.  It seems to me that the high-end folks are remiss in not
attempting to analyze that effect so they can allow for it when they
are trying to evaluate some new device or technique by listening.  No
matter how valid the claims in favor of any particular device may be,
if those claims are not backed up by truly double-blind testing of the
utmost trustworthiness, there will always be room for doubt - the small,
insinuating voice that says Maybe they're hearing only what they
expect to hear.

I think we need to investigate and explain the working of the Clean
Car Syndrome as it applies to serious listening to reproduced music.
(I call it the Clean Car Syndrome because, as everyone knows, your car
always runs better right after you wash it.)  I have a few preliminary
thoughts on this.

It's going to be hard for a bunch of nerds and techies to design
experiments that reveal what a listener is perceiving.  Maybe we need
to do some background research on the design of psychoacoustic
experiments.  

One approach might be to try to get a handle on how much we remember
of a complex perception.  When you listen to reproduced music, you are
aware of both the music and the quality of the reproduction.  The
question is, how much of that information do you retain?  Your initial
answer might be `All of it', but I don't see how that's possible.  If
we can show that you don't remember all of it, and better yet get some
measure of how much, we can start trying to convert the following
conjecture into something more like a theorem.

>WATSON'S CONJECTURE:  Because we don't remember everything about a
>reproduced piece of music, there is an element of surprise every time
>we listen to it.

The conjecture helps to explain how it is that we can listen with
interest and pleasure to recorded music we have heard many times.
Even though we know the music, we do not know every detail of its
performance and reproduction; if we listen attentively, we are certain
to hear a least a few things that we do not remember.

I think this could be developed into a useful argument.  Of cuss, I
don't know where to try to publish it.  The high end people are
certainly not going to want to hear about this, because it calls into
question some of their most closely-held shibboleths.  Maybe I can
start an underground publication...
