Amazingly enough, I haven't experienced any problems with CDs failing - had a couple that were bad from the get-go (one in the the late '80s and another one last year). Even the first one I purchased 31 years ago, which I subjected to intentional poor handling (dropping it on the floor, etc), plays and ripped flawlessly (dbpoweramp - no retries). I have most of the first couple hundred that were manufactured in Germany (lived there at the time). Heck, even my Philips CD100 still works (as long as it's not on a flat surface (well, that was true a few years ago when I last dug it out of the closet)) - as does the demo CD that came with it.
So far, I haven't noticed the first problem with an SACD, although my first real SACD player (Marantz SA8260) did go south. Marantz repaired it though, and it's been flawless since.
