Do all CD players benefit from burn in?


Is it a general rule to burn them in for a few hundred hours? I have found that the handful of CD players (or DAC/Transport combos) I've owned seem to get better, especially in the frequency extremes (more control, less boom or sizzle).

I have usually seen the figure of 50 hours quoted for CD players, which was about right for mine. Things like tubes will take a little longer, more like the 200 hour figure.
Mark Gurvey of TEAC & Esoteric told me that the DACs take about 400 hours to fully settle in. I've also heard that figure bandied about on other forums and posts. I have no reason to doubt it.
'settle in', give me a break. the high end business model is built on that type of nonsense.
Considering all the wire,capacitors,resistors, transitors,tubes,transformers(more wire yet again!)etc. It`s only logical that all of these components need time to form and become seasoned. At lease in my experiences every component has improved with the additional hours(some subtle and others dramatically).Oops! almost forgot, YMMV.
Like Buconero117, for the longest time I thought component burn-in was a load B.S . It just sounded like a load of crap and that it was really just a period of time for the listener to adjustment to the new sound .I now know differently.
