^^I consider CD's/DVD's digital Riff, but I get what you mean. I have All of my CD's ripped and stored on a Hard Drive. In case something happens I simply make a new "perfect" copy. I'm not replacing my library ever again.
^^I have well over 6,000 albums now Riff, it would be impossible for me to wear them out...but I would advise anyone who likes their CD's especially the rare or OOP ones to make copies. That way you don't have to worry about buying another one, if you can find it at all.
Aren't those also quite a chore to set-up and start? I am aware of users who said that they made superior recordings on them because it utilized a larger tape.
