Why no “Break in” period?


If people say there’s a break in period for everything from Amps to cartridges to cables to basically everything... why is it with new power conditioners that people say they immediately notice “the floor drop away” etc.  Why no break in on that?

I’m not trying to be snarky - I’m genuinely asking.

All this talk makes me laugh. Has anyone here been to an audiologist ("hearing doctor") I doubt it. If you do go to one, you will probably learn that your ears and your hearing are basically no different than anyone else around your age. A few will have a little poorer hearing and some will have a little better but none will hear outside the realm of human hearing, like bats and dogs. I worked st a Detroiy auto plant. All employees had to take a hearing test every 6 months,  no ex exceptions. Almost all came back normal.

People that claim they hear things that others dont are probably confusing familiarity with sensitivity. For example if you hear something once or twice a day for years and then one day it slightly changes, that is familiarity, not sensitivty.

The most objective test of hearing that I have witnessed was a test administered by a Proffessor of Music at at a university niversity in NY who is an instructor of guitar. He took a student that has perfect pitch (been tested) and had her favorite songs (she was familiar with) played through high end headphones and tried to distinguish between vinyl and CD. She failed, her percent of correct responses was no higher than the success rate of someone who guesses without even listening.  The test was not exhaustive, I would have done it differently, but it did convince me that those that claim they hear what others dont, are wrong. I think Mr. Carbon is confusing familiarity with sensitivity. For those Interested, the test was published by Rock Beato on YouTube so you can watch it yourself and come to your own conclusions.
geoffkait, what in god's name are you talking about? A single experiment can be perfectly valid if done correctly. "Sorry pal" is offensive. Do you really need to be as immature as rodman? All you have to say is that you have faith (The Cure) that "break in" exists for electronics and no mater what you tell me I am going to believe in that. I can live with that and I know for a fact prof can also. Then we can just discount everything else you have to say as a religious moment and be done with it.

Markpop, I am a doctor and I do have a complete computerized audio logic set up. We have to test hearing for certain professionals and thank you. You are quite correct. I meant essentially the same thing using the analogy of a cat meow vs a dog bark. I do know of that test and I wish he had done it on a few audiophiles using high res vs CD res. Vinyl I think most of us could pick up by the back ground noise.
geoff,

In your rush to judge you have, as usual, misunderstood the point. If you ever slow down to read before firing off a rant, it would have been blazingly obvious I wasn’t taking about what conclusions I would actually draw in the scenario I outlined, but rather probing rodman with questions about what conclusions HE would think to be reasonable.

rodman,

I asked you sincere questions to try and understand your position.

Ok, you don’t want to have a conversation where you think through your position to show anyone else it actually makes sense. I guess the whole "here are the reasons why you should take my claim seriously" stuff is just "blah, blah, blah" to you? (I infer this from your constant disparagement of any questions about your claims).

I find that strange, but if that’s how you like to roll, suit yourself.

>>>>>What a pretty thought - that you know all the variables involved and how to control them. Good luck with that! Oh, you mean some anonymous person out there knows all the variables and how to control them? Good luck with that too!
