If you use the burst mode, it should be able to rip >24x, but the quality may vary.
However, EAC is famous of EXACT AUDIO COPY(Even though it may not rip EXACTLY in real life). If you want to make a secure backup, you may need to pay some time and use the secure mode. (I am a paranoid :), I use APE format most )
EAC also supports for burst mode, you may try.
Enjoy your music!
