There have been plenty of double-blind studies done at
Hydrogen Audio that show that recent versions of LAME can
achieve perceptual transparency (i.e., the inability of most
listeners to distinguish the MP3 from the original .wav) at
around the -V5 setting, which is a VBR setting that averages
about 130kbps.

Foorbar2000 has built ABX comparison functionality that
allows you to easily conduct your own double-blind tests.
Try it. Rip a .wav to MP3 using LAME 3.97 and compare it in
Foobar2000. You'd be surprised at how difficult it is to
distinguish the MP3 from the original.
