Would treated CD's or OOP's-hold its value later?

I have used sound rings on a lot my CD's from Simms to Monster and the manufacture says do not use them on a In dash cd player cause the rings can come off. The rings can be removed and with some elbow grease you can get the adhesive off. It just depends if you hear a difference thats all. I use them on older CD's basicaly 1st generation stuff when alot of the music I listened to in jr high and high school was first being remastered.
I can't hear a difference with the newer ADD or DDD discs though. So someone who was going to purchase something your selling might not want the sound ring on there.

I can assure you that shaving the sides of the cd polymer does not make it sound any better. Nor does coloring the edges with a special marker, but if you want to destroy your CDs because you think it does then knock yourself out.

Viridian/Qdrone/Shawn thanks for your insights. I will stick to no modification, as it's just not seem to be worth the extra 5% sound improvement.

Actually circumcision can be reversed...kinda. You guys never seen that episode of Penn & Teller's BS I take it? There's apparently an entire movement of people angry with their parents for making such a decision without their consent so they've figured out a way to get their turtleneck back. It looked rather painful with weights and what-not. I think it was an episode from their second or third season.

As silly as it may sound, I use a spray on-wipe off product called Shine-Ola on my CD's (and DVD's) and it really works. I had used RRL fluids for vinyl records for some time and a member advised that I try their Shine-Ola. It seems to add more depth and clarity to CD's and more detail and crispness to DVD's. I am not sure how it works, but it does no damage and does not alter the disc in any way, so it may be worth your while to try
