Favorite CD treatment Products

I haven't found extension, but more clarity across the board. As I listen to more treated discs I find they have more information available. I'm hearing many things I didn't in the past making the tracks sound more alive. From the top to the bottom the music sounds more defined. I'm hearing lower bass more clearly in areas I didn't notice was there prior to the treatment. I'm hearing a lot of percussion in the midband I didn't notice before. I think it just allows everything equal space to shine where areas where muddied over before. Like standing at the end of a long hallway hearing the tunes, then walking into the room difference.

Abucktwoeighty has a very fine system. What he is reporting is very similar to what I hear over my smaller system. Do read his comments as I find them very accurate. Thanks again to all the discussion. I never realized cd could be this much plain old fun to listen to.....regards, bluenose

@Bluenose & Abucktwoeight...Thank you guys so much for your help in taking the time to explain. Really appreciate it.

Got to thinking about what Geoff asked. What is being left on the disc after buffing, leaving no residue? The first thing that came to mind was putting RainX on my windshield. RainX says it seals microscopic pores of glass with a super-slick, non-stick invisible barrier. So...
I have 2 Freedy Johnston/This Perfect World cd's, one is control, the other RainX treated. As I was treating the disc, I noticed my fingers felt slippery, slick like when I used the EOM. After playing one, then the other over and over again, I noticed no change whatsoever. Hoped for a change, but alas...would have been a cheap tweak if...

The word invisible can be a little bit misleading since the way CDs work is based on several things, not the least of which are laser wavelength and width, geometry of the disc and CD transport, the index of refraction of polycarbonate and the transparency of the polycarbonate layer of the disc -which is in fact not perfectly transparent. The transparency of polycarbonate is only around 90% or so so even if a particular CD treatment is absolutely transparent to the laser light (infrared) the clear layer is still 90% transparent at best. One would also prefer a CD treatment NOT to affect the Index of Refraction of the polycarbonate layer since that could aftect the geometry that has all been worked out already, no?
