You will find that most of your CDs do no actually rip perfectly. I was very surprised when I moved to EAC when I discovered that many CDs without visible damage require multiple passes to get an accurate rip.

I only discovered this because I was forced to switch to EAC because I was considering joining an elite MP3 swapping group (which in the end I decided not to do). In my case, even using EAC rather than Audiograbber the process doesn't take much longer, because I have a very slow CPU so LAME accounts for 90% of the time it takes me to rip/encode a CD...
