I've never understood this whole "burn-in" thing, at least for solid state equipment. Being an engineer, I find it hard to believe there are any significant changes occurring during a burn-in period that will result in any audible difference.

I can at least believe there might be a change with speakers, as they are electromechanical devices. It's conceivable they might change when played for a while after their manufacture. Given that there are adhesives, wood cabinets, finishes, etc., it certainly seems conceivable. Everything else I have to write off as people getting used to their new gear, not the gear itself changing.

Still, if you grow to like your gear over time after you get it home, that's not a bad thing. I do believe that it takes a while to get used to new audio equipment, and understand what you are now hearing as compared to your old gear. Really, though, that's *you* burning in, not the equipment.
