Spay for CD

@roberjerman   +1 to Geoff pointing out the analog nature of the reading of the binary digital code.   Any "tweaks" that enable your player or transport to read the digital data on your silver discs will yield sonic benefits.  As far as "Spaying", I treat every CD or SACD with Rain-X.  No, it's not just for windshields!💿📀

Try the Audiotop CD treatment. 

 Light is not effected by magnetic fields so drop that as an issue for reading the CD, only after it has been converted to electrical signals will it be effected by the magnetic fields. vibrations, out of round, miss reads etc are the issues and no amount of snake oil on the CD will stop that. clean scratch free CD is the best we can do.    

OK, have it your way. Light is not affected by magnetic fields. Then how can you explain why demagnetizing a CD improves the sound?
