Half the information on CDs is analogue

I would like to argue that one of the reasons that some transports sound significantly better than others is because much of the information on a given CD is actually analogue (analog) information.
An excellent transport does not just read digital information: 1s and 0s (offs and ons); it must be sensitive enough to pick up the other information that has been stored as a physical property of the CD medium. This 'physical' information, like the tiny bumps in the groove of a vinyl record, is analogue information.

Before I say more I'd like to hear what others think.

Sdatch,

CD uses Solomon Reed coding to protect data integraty ....

http://en.wikipedia.org/wiki/Reed-Solomon_error_correction

This means that small analog imperfections have no influence on how the CD sounds, as the data is completely corrected for errors...

Put your CD player on top of your speaker and listen to how wonderful error correction sounds.
Using a mathematical algorithm to fill in gaps and help plot a wave by taking 'best guesses' sounds exactly how you'd expect it sound.

Exlibris...Your mention of "gaps" and "best guesses" indicates that you have no idea how R-S error correction encoding works. Go study!!

From the wiki link:
"In the same sense that one can correct a curve by interpolating past a gap, a Reed-Solomon code can bridge a series of errors in a block of data to recover the coefficients of the polynomial that drew the original curve."
