What are you all doing to modify your cds?

I gave up my muscle car, GTO, a while ago but now have the new Z. Maybe I will add a blower or two on it in a year or two. Oh yeah, I have also tried some juice and edge markers and sometimes they do make a difference but for the price they are all worth a try. Someone told me that the different edges on the CD is the reason why the edge markers work or do not work.

Happy Listening! YMMV!!!
