Breaking in a receiver

i just bought a denon 685 receiver...how many hours does it take to break one in? thanks.

The answer is: Zero!

Would that include a drop test? Just kidding.

As was stated above, zero. Well, not quite. As long as it takes for sound to come on after turn on. This 'break in' is an audio myth, voodoo.

As noted above 0 is the correct answer. It's right up there with breaking in speaker wire. Hard for me to imagine that there is someone out there that honestly believes that copper wire has to be broken in.

Their are many differing opionions on this, as for me, I'll believe someone like at Cary Audio who say that break-in period on their amps is 100 hours.

There is a vast difference between opinion and fact. You obviously do not know very much about electronics. If you gotta believe someone, believe mtrycrafts. He knows what he is talking about. The person your are speaking of at Cary Audio probably doesn't know the difference between a resistor and a capacitor.

Yo Mtrycrafts!! Ya forgot one..

The shake and bake test. The military does it for all of their electrical components... *G*

I believe in a little warm up time maybe, not that I practise it myself. Warmup is based strictly from semiconductor theorey only but thats about it.

Don't tell me what I know and don't know about electronics.

As far as believing mtry, yeah I know all amps sound the same.

For your information Cary Audio is a high end audio company, so what would they have to gain by saying their equipment sounds great out of the box, but it gets even more detail and depth after it's broke in. Again what would they gain.

When did mtrycrafts state that "all amps sound the same"? Or are you providing inaccurate information?

They don't have to gain anything. They just need to be ignorant. Apparently a common phenomenon among so-called hi-end product designers.

Do they really do it to eliminate infant product failure? I'd love to see the factory with all these amps plugged in for 100 hours. Electric bill must be a big one

I'm not trying to get into a piss1ng match with anyone, so maybe I should have stated that mtry believes sonically all amps sound the same in a double blind test. Would that be more accurate mtry?

Apparently you have not paid attention to what mtry has stated. I'm sure he'll probably chime in here to clear things up.

No, I doubt he said that in such broad terms.

It's OK to talk about a topic if you are not an expert. It's OK to voice your opinion. I'd avoid tossing out jabs, however, towards people who seem to disagree with you.

The incentive any manufacturer would have for claiming break-in, since you asked, is three-fold:

1- it often extends well into the warranty period
2- it often allows a user's EARS to break-in to the product (remember that song on the radio you hated when it came out, but later tolerated or even liked since you heard it 100 times?)
3- it allows the manufacturer to belong to an elite group of audiophiles who have certain expectations abut the products they buy and how they should perform/operate.

I hope this gives you some food for thought - that's why we're here...

This coupled with the fact that some people believe or assume if it is made by ABC or costs $x000.00 or requires break-in, it must be "audiophile" grade.

Personally, if someone tells me that a speaker/ wire/ amp requires break-in, I will completely disregard that persons opinion in future.

Since they are both considered well designed, no reason why they would sound audibly different, in either condition. Modern components are transparent withing their design limits.

One of mtry's quotes, above, maybe I'm reading it wrong, when someone says "transparent", I am taking it to mean they really sound the same.

Sorry mtry for dragging you into this, could you explain to me what you mean by the above quote?

I didn't think I was taking jabs at anyone, this is what I honestly thought he was saying.

Thanks Clint for your explanations.

This is a quote from one of Cary's manuals.

3.2 Break In Period

The transistors and capacitors take approximately 100 hours of music playing to fully settle in for peak performance. The Cinema A-5 will sound good right out of the box and continue to improve as it goes through 'break in.' After the first couple of hours you will notice increased depth and tighter bass. This break in period defies engineering theory, but is nevertheless true with most audio amplifiers.


I was just trying to point out, people have differing opinions on this and even the so called experts don't always agree.

The REAL reasons receivers need to be "broken in"

1. Gives the dialectic on the hoosits time to melt and become chocolaty
2. Allows the electrons to align and vibrate in time to the music being played
3. Gives the internal stabilizers time to create the proper vibration free field
4. Allows all the "dirty" power stored up on the power lines to pass through getting to the "clean" power
5. Allows the receiver to emit the proper "good vibes" aura that will intersect with your chi to create a harmonious balance allowing you to hear things that only dogs, bees, and high-end audio reviewers can hear
6. Gives time for the static electricity built up in your wires to dissipate through the patented "take the sap's money" technology
7. It's an easy way to get you off the tech support/returns line

See....another opinion

I knew their was a reason [reasons] for break in.

Warm up yes, but it will warm up nicely while you listen to it

But, this is different from what people really mean by a break in process.

Yes, the shake and bake. I doubt your home audio needs that standard, LOL. Unless, you plan on launching your home into orbit.
