After I learned the hard way, the most important when ripping is to make sure to enable read and ripping verification. It slows down the process, but since I have started to use those features some 5000 CDs ago, I have never had a bad track again. Used to be a bad surprise for a least 2% and then, when I re-scanned everything, I found over 20% of my older rips had some errors in it (most not consciously audible).
dbPowerAmp is a good tool, very flexible. Not the easiest to use in all cases, but you will never get disappointed with the results.
