I now use CDex, back when I switched over from Audio Grabber. I did some ripping tests both in the inner and outer tracks of cd's.

Audio Grabber, EAC and CDex ALL ripped the tracks EXACTLY the same. I used a CRC check to compare the files.

I was using a Panasonic 32X CD-Rom back then.

So if you use LAME 3.90 or higher you’ll get the same results with all of the above packages if your cd-rom supports ripping of course
