Grant, I've got to ask…….. what is there within a CD player that takes up to three hours to 'settle in' ?
Companies that make Digital products such as Bel Canto and DCS have long advocated warm-up of the DAC/CD/Clock devices. John Stronzer of Bel Canto or David Steven of DCS could explain it some detail, but in general it has to do with the DAC's stabilizing after having been off for any length of time.
With Tube amps, the guys at ARC, VAC, LAMM, Atmasphere, VTL and others would explain thermal issues and tubes coming to balance. Any number of solid-state electronics engineers have explained why the warm-up of their transformers for several hours is important before critical listening.
Each category of product may have different issues that lead to needing "on-time" of some variation from an hour to several hours to sound their best (some advocate longer), but they all agree that warm up after being off is important. For cables break-in/warm-up is not nearly as well understood, so controversy usually follows such discussions on the internet. That's why I'm not sure its a great idea to import and post cable "break-in" posts from other forums without any context. It tends to invite argument, off topic comments and incivility from my experience.
I apologize if I could not fully explain the technical reason CDP's require some play time after being off, but I'm sure if you reached out to any competent digital engineer in our field they'd tell you more than you wanted to know… They've done that with me and of course, um, I didn't retain that information…
