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!💿📀

@ebm   The OP is a relative newbie.  He/she may not have been around for that thread.🙃

The first article posted by Rodman99999 stated the relationship of photons to electromagnetic waves as succinctly as I've had the fortune to read.  Saying "The magnetic field isn't made of photons. Photons are made of magnetic (rather, electromagnetic) fields. To be specific, photons are ripples in the electromagnetic field. So, a magnet is surrounded by a magnetic field. If the magnet is not moving, then the field is stationary, and there are no photons. Wiggle the magnet, and the field wiggles. If some of these wiggles propagate away from the magnet, then those are photons."

@geoffkait   Not looking to argue as I didn't make that blog post and do not claim expertise in the matter.  I don't see mention of "seeing" photons in the blog post you quoted above.
