Jitter Question on Dual Deck CDR


Hello everyone, here is a question for those of you who know a lot about digital "jitter" in CD components. I have a dual deck audio cd burner that I use to make copies of my CD's onto CDR, and lets assume that the deck introduces some jitter into the newly created CDR. Now if I play back the CDR on (a) my CD transport, through an anti-jitter device such as AA DTI or SF ultrajitterbug, then to D/A, or (b) through a low jitter CD player, (question:) is the jitter on the source CDR removed/ameloriated or is it too late since the jitter is present on the source CDR itself rather than introduced during playback which seems what most jitter solutions are addressed at?
whew, that turned out to be a long question
- thanks

G, do you think that there would be any improvement by upgrading the passive parts i.e. caps, resistors, beefing up / regulating / filtering the power supplies in the D to D signal section ? Sean

Sean,
No I don't. Remember that the upgrades you mention are upgrades which can positively affect playback in the *analog* domain or perhaps during the D to A process. But a D to D copy is simply not an audio event.

As a silly example, imagine you had a magnifying glass and a device which allowed you to burn a cd one bit at a time. You decide to copy a certain cd by reading one bit from the original and then burning that same bit on the new cd. Do you think that eating steak and eggs for breakfast (beefing up power)/eating breakfast slowly (regulating power)/eating egg beaters (filtering power) will affect the quality of the copy you are making?
I can see your point, but all you've really done is made me hungry : ) Thanks for taking the time to respond and answering my questions. Sean

@gboren +1 Thank you for a such a cogent response! With today's proliferation of expensive CD transports and the claim that some sound "better" than others your answer should give makers of such claims to pause!
