Another way to look at it is that CD defects have much less impact ripping with DBpoweramp compared to scratches or other defects on a vinyl LP. I've ripped thousands of CDs and can only cite one or two cases where the ripped files (often from CDs acquired used on the cheap) demonstrated audible defects upon playback. Not worth losing any sleep over.
If the CD is in such bad shape, and you gotta have absolute perfection, just buy a new copy in better condition.
If the prolonged re-rips are occurring regularly, on many CDs that appear to be in good shape even with no manufacturing defects, then it might be time for a new CD reader. As long as it is in good operating condition and of good quality capable of high speed reads, you are good to go. Most reputable CD readers used with any name brand home computer these days in good working order should fit the bill and need not cost a premium just for this application.
