Yeah, I think that's more likely. I remember reading about a double blind test between Dolby Digital and TrueHD and the results were that only the sound editor could tell the difference. The other listeners couldn't do better than 50/50.
And breaking in a receiver is just silly. Even if there was a break-in effect, why wouldn't you just use the receiver as normal and let it break in while you're enjoying it?
I think the breaking in that occurs is your brain getting used to whatever you're listening to, not the gear itself.
