For a CD it is imposible to introduce jitter, same as it is for cables. You need to understand concept of serial and parallel transfer of data. Any jitter introduced while data is in serial form is meaningless as long as data can be received without bit errors. If it is received with bit errors entire connection can crash, and then must be recovered again, (automatic ofcourse). There is no way to make this inaudible, as this may need up to several seconds to sync all clocks and colided data. Now, to do A/D conversion data MUST be in parallel form. You people need to understand this idea. To convert serial to paralel you MUST have a buffer memory to store serial data first. So any jitter already introduced is meaningles as data is clocked again to go from serial to paralel. The only jitter important is when you go from parallel to analogue. Now keep in mind that data through a cable are serial, where jitter does not matter, and data from CD is read in serial form where jitter DOES NOT matter. So if data on CD is without (or with same) bit error rate before and after treatment, is the same, I can guaranty to you there is no difference in audio signal either.
Why do some people find so hard to conform to rules of science? I just don't get it. You are not talking about something that it is mistical or not understood. You are talking about well known things such as 1+1=2. Are you going to argue about this as well? I don't get it.
