Favorite CD treatments?

Mapleshade's micro-smooth - I had two cds that had numerous skips that two CDPs just would not read and play. After applying micro-smooth to each they both played smooth as silk. As for all the other benefits the maker claims I do think I hear a slight improvement in the overall clarity. But for sure it does help laser read the disc. Hey $16.95 is money well spent.

As Jes45 has stated Shine Ola is the one that I used and I must admit it works pretty well. The dealer I go to gave me a money back offer if I did not feel it helped the sound, and it did. David

I'll definitely second you on Herbie's mat, Spencer. Interestingly, it's not that great on SACDs (at least in my changer, the fabulously cheap (and fabulous!) Sony DVP-NC685V). After a little experimentation, an Audio Prism CD Blacklight is the best so far in that system. Don't know why, it's not that great w/CDs...

The only treatment that I've heard an unequivocable improvement on all CDs treated was the use of an edge trimmer that bevels the edge of the CD. An expensive device, and one that I don't plan on getting until data is in on the long-term effect on treated CDs, but it does work.

The product that Larryi is referring to is manufactured by Audio Desk. I have heard redbook discs that have been beveled by this device but recently here on Agon someone mentioned that there might be less than satisfactory results with hybrid discs.
