Neither of these assertions are correct.
Audio CDs use cross-interleaved Reed-Solomon (CIRS) error correction. They only replace errors with silence (or pops on bad kit) when errors exceed the drive's error correction capabilities.
It is entirely possible to achieve bit-perfect audio CD rips and verify that they are exactly the same as other rips, and to correct ripping errors. This is precisely what the AccurateRip database is: a database of drives, offsets, checksums, etc., to guarantee accurate, bit-perfect rips.
I have approximately 500 CDs in my library verified through the AccurateRip database. I know they are exact, bit-perfect rips because the checksums match the checksums in the database.
