Break-in ?


I don't get it. I realize that almost all audio gear requires break-in before things reach their full potential. But having just followed a discussion related to Magico speakers, I heard several people trashing their sound and others defending what are generally regarded as exceptional speakers. Apparently, the defenders claim that Magico speakers in particular need at least 600 hours of break-in prior to which they will sound disappointing. Why is it that component manufacturers dont burn in their products for whatever time is required so that the consumer receives a product in a ready to go state? I'd hate to spend 5 figures or more on a component and have to suffer through break-in wondering if my purchase was a mistake. I think I remember reading somewhere that Classe and/or Bryston burn in their products for 100hrs prior to shipment. Why isn't this standard practice?

About 100 hours is the most I'd expect any speaker driver to take to burn in.

My experience with caps is around 48-72 hours.

Magico's top end uses Mundorf EVO caps, and I have no idea what the burn-in time for those are, but IMHO Magico doesn't deserve such harsh criticism. They're fine. They do some things exceptionally well.
No company is going to tie up resources or floor space to break stuff in especially MAGICO.
Not picking on Magico but I would think any company that is asking you to spend up the type of money they get for their products would do exactly that. Luxury products are high margin. Shouldn't it be something to expect from high end manufactures?  Lower end products have thinner margins and rely more on volume sales. I wouldn't expect them to burn in their products but when your products carry a 5 or 6 figure price tag, why is it too much to ask?

I once bought some Von Schweikert speakers (I think they had aluminum woofers) and they sounded absolutely terrible when first set up. I played them out of phase and face to face for 200 hours! Finally, they became listenable. BTW I ended up selling them.

Not to take sides on Magico. I have no idea whether they are any good or not, and even less idea whether they are good enough to represent good value for money. But I do know a couple things for sure. Besides the obvious, there's guys for whom break-in is word salad because they have no idea what they're talking about. 

One is really good speakers do not necessarily sound really good. The perfect speaker sounds like nothing at all. It sounds like whatever signal goes into it. That's the odds-on favorite, that Magico are indeed good speakers. People are hearing things they never knew was there. Are none to happy with it. And being normal human beings find it easier to shoot the messenger than deal with the message.

There's a lot of that going around. Could almost call it epidemic.

But any time I hear needs a thousand hours to sound good, my gut instinct is, because its crap. What that really means is you need a thousand hours to come to terms with the fact you got bought some crap. Cognitive dissonance takes over, and since the one thing you know for sure is you are an infallible genius incapable of such an enormous blunder then sure enough, thousand hours or so later, gee now all of a sudden its starting to sound good.

Right. 

If it was me I'd give it an hour, maybe try again tomorrow, then admit defeat and move on. But that's me. The guy with the audiophile nirvana system.

Don't let the "snake oiler's" tell you electronic components need weeks, months, years, to "burn in" they don't most stuff has already been taken to operation temperature for a couple of hours to be "adjusted to spec" (bias, dc,etc etc) at the factory.  Electrolytic capacitors take the longest, a couple of hours will see them "properly polarized" if not they are dud caps.
If the those components took months and years to "burn in" then the factory "adjusted to specs" figures will be out to blazes and need readjusting, when you "burn in" for a few months.

The only components in audio systems that "really" needs "burning in" (I think "bedding in" is a better term) and will sound different are the "mechanical devices", tweeters,mids bass drivers, in the speakers will change a bit over time because their roll-surrounds, cones will change compliance, (get stiffer or softer) over time. Also the stuffing inside a speaker will compact over time and "could vary the acoustic damping a little. Even phono cartridges, their cantilever suspension components vary it's compliance over time.

break in takes a long time, potential shows early. 
digital way passed 200
turntable (bearings, motor..30)
cartridges more than 50
amps way passed 300
speakers 100+
cables...hm (especially power cables)
The higher you get the more you wait.


No one (with the exception of ebm) has addressed my original question. Either responses have been that break-in periods are not really necessary or posters go on to list the reasons for and required time for breaking in various components. I'm not questioning the need. The owners manuals for several components i have are specific as to the break-in periods required for their equipment to reach full potential. The question remains  why don't manufacturers bed, burn, or break in their products as part of their provision. This should be especially true when it comes to products commanding 5 or 6 figure price tags.

I said it before in so many words, "they are" and adjusted to specification at operational temperature at the factory.
If they "burnt in" anymore after weeks and months, all the adjustments made would drift also that were made at the factory, and it would then be out of spec, and sound worse
The manufacturers don’t say for you to bring the device back for re-calibration after it’s "burnt it" do they?

Speaker drivers are the exception, as they are mechanical and do change "burn in" from new.
