What is "break in" and what difference does it make? In amps? Preamps? Speakers? More?


Hi folks,

Newbie question. I read often about a break-in period for speakers, amps. Can someone explain what this means, technically and to the listener's ears?

Is there a difference in what one hears when it comes to speaker break-in vs. component break-in?

Are there levels (quality) where break-in makes no difference?

Thanks.

Speaker break in I think is most important, them amplifier and preamp warm up.

 My speakers took about 100 hours to open up.

now a days, I tested it big time.

 If I cold start my system, and play some music, it sounds “sucked in” or just odd.

when I want to listen, I will turn on my system the,night before and leave in the on position, and that night, usually weekends, the sound is more relaxed, airy, comfortable to the ears.
 
Its part of having better gear, and letting the capacitors and the internals get to a constant temp.
 It is true, I can tell a fairly big difference from a cold play (turn on and play a cd straight away)........VS- my 24 hour “ON” warm up.
thre definitely IS a pretty big difference.

even my wife commented, said it sounded more stadium like and th3 vocals were just more open sounding.

when I listen to my stereo, I will turn on the night before and leave on til the following night, there is a difference.

if it is NEW gear, it may take a couple months for u to hear the difference.

 I’m not a believer of power cables, or (depends on cables) the benefit of rca cables, only u can make the decision.
i did hear a difference between some cheap rca cables vs some audioquest rcas’ a while back.

 When I went to the Groneberg rcas’ I did hear more bass extension, and crisper highs, and a,slightly smoother midrange.
 No joke, I was on the side of snake oil for a long time, til those Groneberg rcas’ we’re hooked up and broken in.

some is snake oil, some is truth, you decide.
When my Energy RC-70s’ wee first played, they sounded cold, no bass, midrange was ........I don’t know, justmnot right, I listen to a lot of metal and blues, and it took a while, as recommended by Energy, about 100 hours for them to open up, and I can tell you what a huge difference the breaking in made.
 The treble, bass, midrange, everything just became more clear, more bass, and the treble really became to my liking, as the Energy’s are an extreme warm speaker (depending on the disc, or recording)
 The midrange is some of the most warmest, and clearest I’ve ever heard in a speaker.

 Not talking about etreme volume, or blaring them, they said louder will result in faster break in, to move the woofers more, etc etc....
.
i just played them moderately until , I could hear an audible difference at mnay intervals ,
so ed has, it was glorious, so Ed has they just sounded like crapper.

 It was fun to hear the many different variations in sound, until they became my most perfect sounding speaker!

im so happy with these,!

now, I have a brand new pair of Odyssey kismet+ monos.
still waiting to be picked up, I’ll be going through another 6-10 months of break in with these amazing Odyssey amps.

 I love hearing electronics change, and become what they are eventually!
 This is why we do it, isn’t it?

enjoy the ride.
I am pretty sure everyone agrees speakers need some kind of break in. They are mechanical devices and it takes a while for the cone / surround to become pliable. Next on my list is anything with capacitors. The new dielectric undergoes some changes with use. This phenomenon has been known for over 100 years and is not snake oil. This break in can easily be shown scientifically and some capacitor data sheets even have recommended break in procedures. I don’t have a firm opinion on transistors or IC’s. So lets say maybe (or it won’t hurt).

But when it comes to breaking in a wires, interconnects or speaker cables I don’t buy it. Some people even claim if you unplug, move or even touch a wire it will take some time for it to settle back in.

Others will strongly disagree with what I just said though. And that is why this thread will eventually melt down and turn to......

Some people even claim if you unplug, move or even touch a wire it will take some time for it to settle back in. Besides, speakers are more than simply mechanical devices, you know, what with the internal wiring and electronic crossovers, including capacitors. Not to mention not everyone agrees speakers require break in. 

>>>>You just said it yourself. The dielectric material needs to break in. That itself explains why interconnects, speaker cables, power cords, HDMI cables, digital cables, etc. require break in. Hel-loo!
