Audio CDs live in a world where there is no guarantee that any two passes across a "sector" will ever give the same result. For one thing, there is no error correction. Give up the idea of getting a correct, or "perfect", rip; it's theoretically impossible.

In fact, that's why cdparanoia exists. In the days of CD-ROM drives, the drives were not very good at ripping audio discs, and cdparanoia compensated for the problems. It was also unbelievably slow. Today, DVD drives have a much better disc transport, etc., and a lot of software is smarter than it used to be, so ripping is only a real problem with copy-protected CDs, and very damaged discs.
