Rain-X as CD Enhancement Treatment


I have used the Auric Illuminator treatment on my CD collection for several years now. I am a believer in the AI, and repeated A/B tests of identical treated/untreated CDs bore out significant improvements after treatment with AI.

I ran out of the fluid and my marker dried out, so I was searching for mew treatments on the market before buying another AI kit or choosing something new. That's when I ran across this article by Greg Weaver at Soundstage, where he talks about having used Rain-X and a green marker(Staedtler Lumocolor 357, price about $3.00) as a treatment on his CDs to great effect.

Being the complete geek that I am, I had to try it for my self. I found the marker at Office Depot, and picked up a little bottle of Rain-X for $2.99. I treated a couple of CDs that I have ended up with duplicate copies of (Grant Green's Green Street, Frank Sinatra Sextet Live In Paris)and tested the Rain-X/marker treated vs. untreated disks.

Well, low and behold, the treated disks sounded notably improved; the music was clearer and louder, especially the midrange, the soundstage was larger with better definition and separation of instruments and the bass was tighter and deeper.

I can't say that the Rain-X treatment was or was not better sounding than the AI, but at the least very it is close, for a fraction of the price.

Has anyone else ever tried the Rain-X treatment?

Shadorne...I don't think that Tbg is talking about digital errors, which, as you described, are completely avoided by use of the RS error-correcting code. Anyone who claims that "bits ain't bits" is simply ignorant of digital technology. Tbg says that identical (bit for bit) files sound different when run through the same D/A, amplification, and speakers. In particular it's been said that the sound is louder after the CD is treated. Absurd!

I was not there when this treatment was demo'd so I can't dispute the statement that many people heard a difference. But the reason is not to be found in the digital domain. Many people believe in UFOs.
Eldartford, yea, and many believed in alchemy. Please read what I said about treated disc, in my experience not sounding any different. I have withstood some grief about that from others more accustomed to listening first.

Shadorne, at last you are at least seeking alternative hypotheses. All was doing is reporting several observations.
Eldartford, I have said that the disc which is treated sounds louder than one which is untreated. The phrase "sounds" is perceptual. I would not assert that it actually increases level. However, that is what it sounds like, there is that much of a change in the sound when discs are treated. The entire performance seems much larger, more clean and extended, and louder. On an $80K rig with true full range speakers it's not subtle at all. I have never had a skeptic fail to be swayed after hearing the results. Neither the previous-skeptics nor I have a difinitive explanation, but the results are - yes - undeniable.

Your analogies to UFO's are strained. However, I did see a UFO once. It was orange and triangular, and I do not recall it making a sound, though tried listening for it. It flew like an airplane (straight, not terrifically fast) but, again, it made no sound. I was about 12 at the time, and I told my parents. They scoffed at it, until the next moring Paul Harvey speaking through the kitchen radio announced, "Numerous UFO sightings over Northern Illinois and Southern Wisconsin last night..." My mother was in the kitchen - you should have seen her face! The UFO was a plane painted with gray and florescent stripes taking air samples at dusk as it was flying North. In the twilight at its height it appeared to the naked eye as an orange triangle. The lack of sound was likely due to the influence of wind.

Perceptions are not always wrong. The answer to what lies behind the perceptions is usually logically explainable. However, to scoff at someone who is experiencing something perceptually is often nothing other than arrogance.

I happen not to believe in aliens. I hold that all "UFO" sightings have logical, natural explanations. However, that does not stop people from seeing things which they cannot explain.

Similarly, when individuals like myself report as accurately as we can the experiences we have when conducting listening tests, it's not helpful for someone to argue that we are delusional (placebo effect). So, kindly get off your arrogant UFO analogies. :)

Shadorne fumbled the ball. How would you like to conduct the simple disc treatment/listening test? Will you take the same position that because you already "know" it can't change the outcome you won't conduct the test?

If so, we are assembling a very interesting case study for objectivist behavior. :)
Shadorne fumbled the ball.

Nah - you just imagined it - wishful thinking - the "placebo" effect!

Admit it - you treated the ball with Rain-X so you expected me to drop it! ;-)

we are assembling a very interesting case study for objectivist behavior.

You are obviously referring to me but I would counter by the simple observation that I am one of hundreds of millions of people around the world who would not dream of doing what you suggest unless it was to fix a badly scratched CD that nolonger played properly. Therefore I am actually pretty dull & boring sitting and sharing similar views to the vast majority of CD listeners (who don't polish their CD collection with Rain-X or mark them with green markers).

You however are the "very interesting case study for objectivist behavior"...sitting somewhere way off the end of the bell curve ;-)

More seriously, this banter has been a fun diversion and I am glad the gibes were kept civil & polite. I really don't have much more I can add or share on this matter. I feel certain we are connected through our enjoyment of music and a pursuit of our own respective ideals in audio reproduction equipment even if we don't see eye to eye on Rain-X or what defines excellent equipment (robust vs resolving).
"Bit is just bits," someone said.

"Sometimes a cigar is just a cigar," Freud said.

But Freud also said:

"My boy, smoking is one of the greatest and cheapest enjoyments in life, and if you decide in advance not to smoke, I can only feel sorry for you." (Freud: A Life for Our Time. Peter Gay, 1989, Anchor Books/Doubleday.)
