Writing a CD is a mechanical process that should not be inferred to be perfect. Unless a target CD is verified to be bit-perfect to the original, there's plenty of room for variation. The only expected result is that the copy's data blocks can be corrected by it's parity data before being passed to the DAC. A good portion of the storage on an audio CD is devoted to error correction data. This was particularly pertinent on early players that did not beam-split multi-sample when reading. Incorrect decoding could fry your stuff. The original CD can also be expected to require this kind of correction and contracts to manufacturers usually stipulate how accurate the pressing must be. So it can be safely said that recording (writing) speed can have a real effect on the resulting disk. P -- pski real stereo doesn't just wake the neighbors, it -enrages- them..
