My 2 cents
1) I have observed that CD's copied at a higher speed are less reliable. I attribute this to the shorter amount of time the laser has to burn the pit into the substrate.
2) Much is made of the error correction affecting the sound in CD players. Unless your CDs are pretty beat up, I would guess the error correction is used far less than you think.
My first CD player was a McIntosh MCD7000 (mid 1980's). It had an indicator on the front that would light up EVERY TIME the player was interpolating data (correcting for an unreadable error). Even with that early transport (high speed transports for computers hadn't yet been invented) the light ALMOST NEVER came on. Maybe once every few CD's.
I attribute the differences in CD player sound to other issues, such as D/A's, analog output stages and jitter (another issue altogether - not related to error correction).
