Why no “Break in” period?

@boxer12

geoff, geoff, geoff,... They are the victims here. Just trying to teach us that we can't possibly be hearing what we are hearing.

Who is "they?"
Me (in this very thread):

There is of course nothing wrong with just buying gear and trying it, feeling like it makes a difference we like, and buying it. As I’ve pointed out a million times, I don’t go trying to test everything I buy with scientific rigor.

.....

I am not saying you are wrong in your claims. I’m actually open to the possibility of fuses sounding different, burn-in etc.

And I pointed out I hadn't come to a firm conclusion on the matter myself.

If you switch to M and P, it makes all the difference.
Instead of divergence, there’ll be convergence.
And there’ll be solution to the equations.

HURRY UP PLEASE ITS TIME
Now Albert’s coming back.
Make yourself a bit smart.

We have lingered in the chambers of the sea.
Until the fog horn sounds the alarm.
Our journey from sea to land. 

Prof: +1000.

I get weary of the thinly veiled insults.  And more wearying is the constant shilling for certain cable company.  

Almost as though he has stock in the company.... 

Now good that he likes them and believes in them.  

And good that he listens.

but not good how he insults others by insinuating that he has such superior ears that he knows better than everyone else.  Others can listen.  For sure.

And.... since sound waves can easily be measured (you cannot HEAR it if it is not a sound wave propagating through the air)... changes in electronics should be measurable.   Are measurable.  No data.. then it is just opinion.  There is NOTHING you can hear that sensitive measurement systems cannot pick up and quantify. 

Note: I have been an audiophile for just as long as he has.  since early 70's.  And have been actively listening since then.  My ears are well trained. I even produced music festivals and concerts for a time.  My last festival was so historic that the Smithsonian came out and recorded the 3 days for posterity.

Not sure about  power  conditioners  but when I purchased speakers from a company that does online sales when I asked about break in the president of the company told me the only break in would be me getting used to the speakers. I should give it a month or two before I made a final decision.
