Reading the audio data off CDs is one area of audiophilia that should be quantifiable - is the data read correctly, is it presented at the right time (jitter) and does it affect how hard the servos have to work to recover the data (power supply modulation). Tweak proponents could measure these things and prove efficacy but in the upside down audiophile world it is for the rational to disprove them. Some (many?) believe everything makes a difference and will tweak anything/everything and, perhaps, manufacturers are the same and they don't have a rational idea what they are doing and so wouldn't know how to prove anything.

For full disclosure I think it obvious my expectation bias is that these things don't work so I don't try them. Thus I can't say they don't work, only that it is very unlikely they do.

The polycarbonate layer is not completely transparent to the CD laser. It's only 90%. Whereas optical glass is 97% or higher. That's why some Japanese CDs sound so fabulous, SHM CDs. Super High-performance Materials. They use optical glass for the clear layer. Now, image there's a liquid spray treatment that makes the clear layer behave like optical glass. That would be news, right?

  You almost proposed something that could be quantified in its effect on the signal reflected back to the receiver and, hence, the recovered data. I am sure a few back of the envelope calculations would show us if this is plausible or specious.

        Let me think about it for a few days and I'll get back to you.

    Play a cd. Then put a few drops of dawn or similar on the cd, rinse and wipe dry. Play cd again. Is there a difference?
