I believe you guys, I just don't understand that there are so many reviews, written by people who I would assume know what they're talking about (maybe that's the problem), that talk about "break-in" and "warm-up." If it doesn't matter, why are there so many reviewers out there that say it does make a difference? I'm so confused? Are they all wrong, and if so, why are they then the so called "experts" writing for audiophile type magazines?

I read one review on the Arcam CD192 specifically, that talked about how the unit they tested sounded so different after "breaking-in" for 70+ hours. And there are cd's out there that were developed especially for the purpose of "breaking-in" equipment, cables, etc.? Is it all "snake oil?"
