When AudioGrabber was new it was special. As of now it's just a decent app for ripping in burst mode. Jakie was promissing some sort of secure mode already years ago, but nothing came of that.
Although I had bought AudioGrabber, I stopped using it as soon as I got used to EAC, which has always been free. There's nothing compares to the secure mode of EAC. It takes a bit of learning how to configure it properly for your drives, and it's slower than ripping in burst mode, but it saves me a lot of time by not having to listen to the tracks before burning them. It's the only ripper I trust. If it's says ripping was good, it IS good.
