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.

Yes, what a lovely phrase! It carries the same force as the phrase, "skepticism bias". :) 

And now I return to my writing, as it is a waste of life to argue such things beyond a sentence or two. I have been known to be drawn into such things in the past, but I'm trying to reform myself.  :)
Well said, like others here, on the truth of break in. There's lots of projection going on here that points to "skepticism bias". It's become a well practiced art form and all the usual critters chime in with the same, bland accusations.

Once you've got it down to a few talking points, it doesn't matter what or how you say it, and the ditto heads will nod along in approval. Anything can be made up or added into the mix and it simply strengthens the belief. That, and the tendency to dog pile. It's actually predictable.

The only downside is that this "skepticism bias" has taken on a life of its own and pollutes many a discussion for no real reason other than to be seen as a normal form of communication, which is truly sad.

One of the valid forms of accommodation, in psychology, is a neurotic condition and can apply to certain aspects of authoritarianism. The ditto heads simply follow the strong ones even though they contradict their values, beliefs, mores and folkways. Civility and ethics can go right out the window as long as they win, as a group. Gone, is the open mind. New info need not apply. Closed for business.

That's why Doug is onto to something that I'm gonna try to practice more this year as my one and only resolution: to stop wasting so much time in these silly arguments, and stick to the stuff that matters.

All the best,

And what matters is the sound? That's what I thought.

But if that's the case, and there's people saying there's things can't make any difference when we know they can in fact make things sound better, well then its not silly at all.

At least, and I hate having to say this, but not the way I've done. Read my posts above. Everything is focused on listening- what things matter, what to listen for, how hard it is, that listening is a skill, that it can be learned, that you can learn and get better at it.

Not to say there aren't a lot of people making silly arguments. Actually they are more lame attempts at wit than arguments. But whatever. You get the point. 

If you have something to contribute and keep it to yourself because the loons might squawk, well all that does is cede the ground to the know-nothings, nut jobs and wannabee losers. If you have nothing to contribute then fine, don't. Wish the know-nothing nut job wannabee losers would do this. But they won't. 18,000 posts and counting, no sign of letup any time soon. With new ones coming on board all the time.

If they enjoy banding together bantering brainlessly back and forth and you can see the folly in it, point it out. Skewer them. As best you can. Defeat their arguments wherever and whenever you can. Refute, poke holes, chide, deride. Not all the time. But when and as you're able. 

Otherwise, if the place goes down the sewer and you didn't even try and do anything about it, well at least don't go acting all high and mighty and above it all. Not when you cowered when you could have at least tried to conquer.
Nicely stated. 👍
Pick and choose.
Be selective.
Never cede the high ground.
Know when to hold 'em, know when to fold 'em.....

millercarbon,

Further beating a dead horse, driving the point home, like a stake into the vampires heart, we all know that the reviewer is perfectly capable of then writing about his actual experience of the movie IN SPITE OF EXPECTATIONS!


That's essentially a re-statement of the old "I wasn't expecting to hear X, therefore X is real and not due to expectation bias."



As has been pointed out countless times now, that's a naive understanding of how our biases work.  There are many forms of bias


Here's one list of cognitive biases:


https://en.wikipedia.org/wiki/List_of_cognitive_biases


Simply listening FOR differences can lead you to think you hear a difference even if you don't expect to.  It's just how our brains work.Or, you may not even be listening for a difference, but at some point perceive that "something sounds different in that track from last time" and then presuming there is some objective reason, the audiophile thinks "Ok, what have I switched between, or introduced in to my system lately?  Oh...that power conditioner, THAT must be causing what I think I hear.  Or "oh, I'm sure the sound is different, so it must be BURN IN."


There are so many ways to misapprehend what is actually going on by ascribing a change in subjectivity to some objective change.


This is why when doing, say, medical tests, scientists don't say "Ok, let's round up a bunch of skeptics about this new drug.  If they take it and report subjective changes, then it MUST be due to a property of the drug!"   Scientists don't do that because they know that's a totally ignorant account of how biases can work.   That's why they use control groups, blind and double-blind testing.

Anyone that discredits another’s abilities to hear improvements, in their own systems, in their own listening environments, with their own ears, should be considered condescending, insulting and/or(probably), simply projecting their own ineptitude.

Please see above, rodman.


If you were to be involved in a medical study for a new treatment and they told you they'd be using double-blind protocol so that neither your nor the doctor's biases could confound the results, would you say "No, because the fact that, if I know I'm on the active treatment you won't simply trust my reports as TRUE, means you are being condescending, insulting and projecting your own ineptitude!"


Would you think that's an appropriate response to the idea of controlling for the variable of human bias?


I's simply a falsehood to say "if you didn't experience it, you have no grounds on which to doubt a claim."   Particularly if the claim is in the form of anecdotal evidence, unsupported by objective evidence, careful testing.


If you tell me you bought a perpetual motion machine, it won't matter how much you say "You haven't even tried it, so you don't have any reason to cast doubt on my claim!"   The odds are you are simply mistaken, and you'd need to produce far stronger evidence than "I'm really sure this is happening, and that's good enough!"

Until I took the time to actually listen and compare.




Have you ever gone a step further, and "actually listened and compared" without peeking?


I have. So have many others. It can be very educational, if you are open minded enough to learn that way.



We certainly can hear many things that "really sound different" (due to objective changes in the audible range).


But we can also "hear things" that aren’t objectively there.



So, how do we deal with possible confounding factors?


Blind testing is one way to do it.


Back in the late 90’s I had a couple CD players and a DAC and I was SURE they sounded different. It seemed so obvious! Yet some "objectivists" online said it was unlikely, that a properly constructed DAC should sound the same. (Though, with caveats).


Here’s the thing though: I was willing to accept that I may have been mistaken. I admitted that I’m human, subject to the normal human biases, which could be influencing what I "think" I heard. So I was willing to TEST MY OWN PRESUMPTIONS, and try to distinguish the units without peeking. I did a number of blind-test shoot outs (matching volume output at the speaker terminals).


Guess what?


Positive results! I could EASILY tell the units apart, because they (apparently) REALLY DID have the different characteristics I thought I"d heard.


That was really cool.

(Strictly speaking, this doesn’t entail that the objectivists claim was wrong; they left open that DACs/CDPs could be designed to sound different. Rather, they were pointing out that a well constructed, accurate DAC/CDP should be indistinguishable from another all other things being equal. So it’s not like I "disproved" that particular claim. Rather, I simply found support fro my own impressions that the ones I owned had different sonic characteristics)


BUT....


There have been other results in blind tests I’ve done that indicate that what I thought I was hearing was in error. Once I couldn’t peek at which device was playing in blind testing, the sonic signatures I thought were distinct just weren’t there to distinguish A and B.



Again, this comes from being open-minded enough to simply admit "I’m human, I could be wrong in how I’ve interpreted from my subjective impression to what is really going on."


It’s nothing to be afraid of. Really. It just takes opening your mind, a bit more bravery to truly put your "golden ear" to the test without peeking.
