Good thread. I have used two CD tweaks in my system: one with great results and one with minimal (no) result. The great result was with Optrix; the no result was with the Audioiprism green pen.
The Optrix spray brought a remarkable improvement in low level resolution, especially in my older CD's that I thought were poorly recorded. Because they were "poorly recorded" I hadn't listened to in years. With a good cleaning, wow! This makes sense as they were the oldest and probably the dirtiest CD's I have. Subsequently, they were the most improved by the cleaning.
Unfortunately, the green ink didn't fare as well. I put it on several of my reference discs and fired up the old transport (Muse 5 with a I2S connect to a model 2 plus DAC for reference). No difference. I was bummed, mostly due to the glowing promises from the audio store guys. I certainly had high expectations, but no result. I know others who have had good results with the green pen. I'm not sure why my system did not benefit.
An interesting side note is that the green pen contains a proprietary ink from some Japanese company- I heard all this from a Danish 'phile. Anyway, you can get it in ink pens at a store in Denmark called Koch & Tutein. (Needless to say it's not 16 bucks a pen there). I didn't buy any as it didn't work for me in the Audioprism pen. If anyone has the inkling (no pun intended), try it out.
Happy listening.
