- There is nothing absolute about illusions. As I have mentioned before, the
- amount of information in stereo recordings, coupled with the fact that the
- recordings must be reproduced in ill-defined and variable acoustic
- environments, means that recreating the original experience is certainly
- impossible. One can only attain a pleasing illusion. I think we agree here.
-
- My point is that, since it is illusion that is being attempted, that
- different effects, including euphonic distortions, may help support the
- illusion, even if they represent deviations from true reproduction of a
- recorded signal.

- Statistical measurement of subjective responses is also an objective
- measure. It is an unfair characterization of the objective approach to
- pretend that it's people running around with meters and circuit probes
- saying "Can't measure it. Must not be real."

-
- Maybe Mr. Hirsch doesn't have the most discriminating ear, but I can at
- least trust him. He's not pretending to have skills that he doesn't posess.
- Most of the "highly skilled" lot that you refer to I hardly consider
- something to be thankful for.

-
- It is hardly paranoia to distrust other people's judgments when there are
- so many potential reasons to discount them. These people produce a
- marketable commodity -- their opinions -- and have their egos and their
- wallets riding on the market perception of their talent. Supermarket
- tabloids sell far better than any audio publication. This is no indication
- of the quality of the published material.

-
- It could also show that they respond similarly to the same euphonic
- distortions, or to the same non-audio stimuli, i.e. marketing hype,
- hearsay, and price tags.

-
- Yes, but the life-like quality of an *illusion* is a matter of taste.
- Different sounds will give the illusion of realism to different people.

-
- This is purely a misrepresentation of my viewpoint, and (I believe I can
- speak for him in this matter) Lon's as well. I have said (and obviously
- must repeat) that I make no case about anyone's preferences, nor do I tell
- anyone that their tastes should be based upon measurements. I only object
- when bogus technical claims are made for a given preference or perceived
- deficiency.

- This again is a continuation of your misrepresentation of my viewpoints,

-
- This fact does not undermine the euphonic distortion argument. There are
- professionals who prefer CD sound as well. I think that that shows that
- there is a matter of taste involved in deciding what sounds closer to real,
- and what effects support that illusion for a particular listener.

- ^^^^^^^^^^
-
- Oops! There goes the other foot!
-
- My point is that if you remove (or simply debase as second-rate) all
- objective and statistical methodology, and rely purely (or primarily) on
- uncorrelated, unaccountable subjectivity, you open the door to massive
- self-delusion and a deluge of snake oil.
