Exact Audio Copy is also the only program that can get perfect ripps from damaged Cd's. Cdex's newer versions are getting better but still cannot get the perfect ripps like EAC can.
EAC is slower and a little harder to set up but worth the learning curve
A good tip that will help all ripps with EAC or CDEX is to set the priority level to low. This will do wonders if working with another app "browser/winmx/etc" as even mouse clicks can cause artifacts.
