Mmmm... not the same stuff as you are describing. If disc cleaning is all you're after, well, then just use windex (I don't believe you should, I am just joking here!).
I have yet to try this one. However, I have used L'Art Du Son CD treatment and Optrix as well as others eons ago. L'Art Du Son is superb. There is an immediate and definite improvemment in all areas of sonic playback. Far more "natural" sounding, far more open and dimensional soundstage, improvements in macro and micro dynamic shading, better and more stable imaging, better balance from top to bottom, much less digital glare and grunge (hash, grain), smoother, sweeter, etc.
I can only expect UBP would be fairly the same result. However, there are other optic improvers out on the market. Each does do slightly different sonic changes to the sound. How or why it works is beyond my understanding. All I know is, the playing side of the disc is definitely more clear, clean with "see through" to the aluminum or gold surface.
