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


Hi all,
Please give me some guidance here. Before I go and purchase a German cutter that shaves the sides of the cd polymer off to better the sound. Or all these green markers that you outline the CD with- Would they decrease or increase the value if ever they were to be sold later on in life. i am talking about CD's that are quoted on todays market at US$50 and above. would you buy these or shun away and get a non treated one if you had the option?

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.
