With all the talk about copyright protection on digital discs, it seems to me that one would do fine for all but the most critical listening tests, making cassette tapes on a good machine. The only drawback I see is not being able to easily select individual tracks. Same goes for LP's. Unless you do a lot of remastering (to remove noise) why go through the hassle of digitizing them to write a CD?
Also, if you must copy a CD in digital form, I think that you could redigitize the analog playback of the original disc. If the digital recording equipment is good the digital disc you make will be as good as the playback of the original disc. All this copyright protection stuff is based on the premice that a digital copy must be made without going through an analog step. Not so. Digital to Digital is obviously the simple way to assure quality, but not the only way.
