CDex is an old-fashioned tool (release 1.51 from September 2003!!) but surely still one of the best Audio CD Ripper. Completely free (Open Source), very powerful but quite easy to use, very stable. A must-have.
I ripped about almost all my CDs (> 900) with this tool.

Mainly focused on ripping and converting, things like turning your home Compact Disc collection into an mp3 collection on your hard drive become extremely easy.
