Forgot to mention, I would say minimum 100 hours, but some digital gear definitely benefits from much longer play time. When I bought my first AK240 six years ago, it took about 400 hours of play. This unit had a defect after a month, so iriver swapped it out with a new unit and sure enough, the new unit sounded very bright out of the box. Once I got some extended play time on it, the brightness that was bothersome was no longer present. I went through this same process when I bought my AK240SS five years ago.
High quality capacitors go through what is called a forming process once signal starts passing through them. Initially, signal is absorbed by the dielectric of the capacitor and then re-released back into the main signal flow thus causing a smearing of transients resulting in a bright, edgy sound. As the capacitors form, this dielectric absorption lessens.
