Have a look at this thread:
http://www.hydrogenaudio.org/forums/index....c=65534&hl=Many people seem to get 3.98.x going with this, but as you can see from my bleats, my files come up commented as encoded with v.3.97, and I don't know enough to tell whether this is merely a clerical error (version number hard-coded in the script or summat), or a sign of something really wrong.
I used to use Max, by sbooth, which kept me happy and has a good rep. as a Mac ripper and file fiddler. My only reason for changing was that the metadata look-up in iTunes is better; I was ripping with Max, then importing into iTunes and doing some tagging by hand.
Although I'm sure 3.98.2 is an improvement, the comments made suggest it is incremental, rather than any kind of step-change. Certainly no-one's saying we should go and re-rip our CDs to get rid of our crusty old 3.97 files.
HTH
