Sean, Cable Co has been trying to convince me to get the Audio Desk CD lathe but it is a very expensive tweak and obviously irreversable if you change your mind. Sanding the edges of CD is similar to blackening edges, trying to minimize light scatter. I am very positve about Auric Illuminator after testing several similar products using duplicate CDs. I also like to demagnitize using Bedini II. The ultimate tweaked CD according to Cable Co is Audio Desk Lathe/Furutech RD-1 (demag)/Auric Illuminator triple treatment.......BTW if you get duplicate CDs you can send one to Cable Co and they will but it on A.D. lathe and return it to you, Sam
CD other tweaks
Over the week-end, I had the chance to try an audio tweak.. sanding the outside rim of a CD, the impact was great. I have tried the paint route and had some success..but I had heard about using very fine grit sandpaper on the outside rim of a CD. I tried it and it was up there with major component changes. The most hear-able differences were: a more quiet or "blacker" silence between notes..and a sense or more detail..but more ease at the same time. Has anyone else tried this?
