Have we "talked" since the TAN days? I can't recall.
Frankly I don't know enough technically of how a CD works to be able to know if a "polarity inversion" could even take place reading the disc. It would seem to me like there would be a bit used to define the polarity and if that is the case why would it be the only one flopped?
I guess we should ask a digital engineer how and what is swapped when the digital domain "polarity switch" is hit.
In any case I think it is pretty clear George is contending that all or whatever % of machines he thinks it is inverse polarity relative to that which it should be according to what is stored on the disc.
Anything is possible but even if true it makes absolutely no difference, right?
Cheers and HNY!
