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?

Mr E- Yeah, There's no doubt that they do work, and very well(hard for me to swallow, given my reactions to some of Amar's past concoctions). Did he learn advertising at MIT too?
OK. I did the test.

First of all I connected my CD player directly to one of my Behringer DEQ2496. The 2496 logs the peak signal level over the course of a complete CD. I made the hookup directly so that there was no gain control in the signal path. I played a CD twice, before and after treatment. For the two playings, the peak signal level was identical for both channels...-4.2dB for Left and -4.1 for right. That proves to me that there is no increase of loudness as a result of treatment.

With regard to sonic quality, I heard no difference, but this kind of comparison is difficult, and highly subjective, and everyone is free to believe what they want. I know what I think.
Eldartford, thank you for conducting a test of the disc treatment. I respect people who actually will try such things. I also will accept your experience and not debate it. Variety of experiences makes for interesting exchanges between audio lovers.
So, Doug, are you changing your opinion? I continue to be perplexed at sincere beliefs that some hear differences and others do not. I am also fascinated that some love one wine while others hate it. Humans are a varied lot.

I remember several years ago sitting between John Curl and an TAS reviewer listening to a demonstration of the Shun Mook speakers. John and I were struck by the improvement gained by a slight change they made in the speakers. The reviewer heard nothing. My only judgment was that I would pay no attention to his reviews thereafter. He was soon gone.
