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 feel that you are correct in burning a cd player in for a couple of hundred hours.
There are a lot of capacitors to burn in.
There's OPAmps to burn in also.
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.
