CIRC. My apologies: You mean this?:

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

Read that and come back and tell me that you can't get a bit perfect
stream from a CD player.

I appreciate that there may be firmware that chooses not to report
errors, but which computer drives do you know which don't report
errors? EAC itself reports the errors the drive has flagged. I'm sure
there are some dodgy old CD readers out there, but I don't have one of
them.

When I rip with WMP, it is easy to spot when it has come across an
error... the only way it can know is through what the CD player tells
it as it reads the stream.

Your comment about checksums is fair enough. What you're saying is that
the checksum is your guarantee that you ripped the same bits as someone
else, and you're right to point out that, even if to me the rip went
without a hitch, a checksum is a rock solid guarantee.
