I think ph349397's question, and I know my answer, was directed towards stand-alone consumer grade stereo component burners, not PC burners. So the programs such as EAC, Feurio, CloneCD, Alcohol 120% aren't relevant to this particular question. The stand-alone burners have at least the ability to implement copy-of-copy protection in a non-defeatable manner since their software can't be changed by the user.
As to the broader question of copy protection on audio CD's, what about Cactus Data Shield, Key2Audio, SafeAudio, etc.? Are you saying EAC can handle these? I don't believe that is the case, although I think CloneCD and Alcohol 120% can. I have no personal experience.
