Break In Question?

Yes. That's true. 

Any new component you add to your system needs to "break in" or "burn in" just like a car achieves its intended engineering spec a few days after it drives off the lot brand new.

Machines like audio equipment need all internal parts to fully stabilize. This happens over many hours. Capacitors, resistors, etc. 

After years of being fed up spending hours noticing improvements, I found this on YouTube. 

The Angel's Burn in for Audio Components

Turn down the volume on you preamp fully and gradually increase until it's at a comfortable level. Then play it from the start.

One play is all I needed. The difference was real. And after it, I didn't need to keep burning it in.  

@douglas_schroeder There is a night and day difference between sound quality of a cool amp vs a warmed up amp (90 mins+). This is especially true in Tube amplifiers and class A amplifiers.

Anyone who disagree with this, I can’t take them seriously because I know for a fact their ears are unreliable. To even suggest the warmed up sound is identical to a cool one is WILD. 

Erin the Youtuber, and the guy from ASR that do a lot of reviews, he has publicly admitted many times all amplifiers sound the same to him. Is he right? Absolutely not. Borderline crazy actually. BUT, what I really respect is that he says they all sound identical to him, not that all of them are identical.

Anyone that says warmed up time is BS, I know best to not take anything else they say seriously. If a reviewer can't see farther than 20 ft, why should I listen to what he says about what's 25ft away. 

When I started in this hobby, I was precisely like most of you, self-assured, ready to debate anyone who disagreed.

@douglas_schroeder This is not a good mentality. Also an awkward one, whenever someone started new in a hobby, any hobby, their experience and knowledge is low, so should learn what people have to say rather than disagree with fragile foundation. 

There is something fundamentally wrong about someone of age telling others their hearing is unreliable. 

I'm sorry for pulling out the age card but it's a fact of life that none of us can avoid. And is actually a crucial component in any discussion. 

samureyex,there is something fundamentally wrong about someone who has zero experience with the testing proclaiming what happened during the testing.  :(

Your logic is poor. The supposed basis for break in is the perception that the equipment is changing over time. I have repeatedly said that I experience that perception regularly, every time I set up a new rig or introduce a new component. If that is the standard for good hearing, then my ears are as good as anyone here regardless of age. 

Yet, when I discuss the testing regarding break in, then somehow my ears or perception is faulty. That is a non sequitur.
