Yes, indeed!  Just to give some results:

jkh@time-> ls -l wrong.wav 
-rwxrwxr-x  1 root  wheel  42705308 Feb 15 00:00 wrong.wav

[A CD tune I recorded as a test]

jkh@time-> ls -l stereo-wrong.mp2 
-rw-rw-r--  1 jkh  jkh  3873509 Feb 16 20:16 stereo-wrong.mp2

That's a LOT of compression! ;-)

I've spent a lot of time listening to both versions now and I swear
I can't tell the difference!
