A question about cable break-in


I have some new ICs and speaker cables, as well as a preamp that need to be broken in. I want to let the system run for about two weeks non-stop, but don't want to have to listen to it like that. If I disconnect the speaker cables from the speakers and leave a cd running so that the signal still goes through the system, can I still achieve break-in?
Thanks for your comments.

To all those asking why I don't just listen to them, well, I will at times, but my wife is now home all the time with our newborn and I don't think she wants to hear it all day long while I break it in. Some interesting comments here, as always, thanks for your input.
How 'bout a testimonial

I sold a pair of NBS Monitor 1 speaker cables to an individual who didn't believe in cable burn-in. He emailed me telling me the cables sucked and that his former Monster Cables were superior. I told him to give the cables a good week or so for them to burn-in, even though they were already used. After a few more "angry" emails from him, I got a strongly worded apology. He claimed all of a sudden the cables began to open up and pull in more detail in the upper ranges, increased resolution, darker background, lower noise floor, etc. He said couldn't believe his ears and his friends couldn't believe their ears either.

He's now a believer!
Dave 1117, I have this question in many different ways in these pages, flippantly, seriously, tongue-in-cheek, etc.. Never got an answer. I think that this may be a reductio ad absurdum, but I think this line of reasoning is a valid way of showing that burnin, while maybe a valid concern on a theoritical level, (more so probably when dealing with transducers since they have a whole mechanical side to them), is, for all practical purposes, a non-issue best left in the hands of the insecure. From the margins of audiophilia, good day.
If we don't understand, or can't explain a phenomenon, it doesn't exist? Is that what you are saying Pbb? With that sort of thinking I am sure our understanding of the physical world around us would never have progressed past what stone age man knew. Pbb, would you pass me that rock?
so it is; we agree, disagree; explain, can't explain:

It's all good.

Now for a serious question. Just tried something new that I am half happy with and half I'm not sure. Please see my post on new cardas golden ref.

Thanks and in all seriousness, HAVE A GREAT NIGHT!!!
