MM has no error detection and correction, which is one reason why it is
so fast. If it gets errors reading the CD, the errors make it into the
music, where they may or may not be audible, depending on the severity
and number of errors encountered.

There is no such thing as "very, very good" sound quality with a 128kbps
MP3. That's like saying that your stock Hyundai Access is very, very fast.

Your assessment is based on the flawed assumption that listening to rips
from CDs A, B, and C will allow you to predict how rips vrom CDs X, Y,
and Z will sound. If X, Y, or Z has uncorrected errors, there may be
significantly degraded sound.
