Burning In Update

[Mackie 0]

Rameish,

 

The concept of burn-in will not mean anything to some if they can't hear the difference during pre and post burn-in period. I'll believe in anything (voodoo included) if I can truly hear a difference.

 

It's all about electron flow and concerning wires, having a signal to travel in the same direction is also sonically beneficial although subtle. Another issue is electromagnetism. Electrons can be magnetised owing to sudden EMI or prolong usage akin to having a dead pixel on a CRT monitor/TV. Degaussing is required to free the electrons and when applied on audio gears, one will hear better flow of the music and most significantly, a more open sound.

 

I will always remember the time when a non-believer in power cords having an impact on sound, had his jaws and eyes agape when I conducted a test. I can't recall his name but he's a fellow member here.

My only gears that gets switched off are the portables ones (because they tend to run out of batteries )

Otherwise my other electronics never gets turned off unless there is a power cut. As for the headphones I usually warm them up for around 30 minutes or so and I'm set for a session.

I once did that with an electronics engineer with interconnects and he still didn't want to belive it. Not a very good electronics engineer i guess. So when I showed him some dh cones he almost fell of his chair but even he had to admit there were sound principles for isolation and damping that could be measured.

btw, nowadays exam period I lazy to off my cdplayer already

both the A3 and corda are well-warmed up throughout this week and next week, I think!

So I all I need to do is to insert a cd and play! yay!

Nice when you don't have to pay for your own electricity bill, no matter how insignificant the amount may be

You will have to be a specialist in material sciences as well to fully understand the property of metals, not to mention hifi nutzs.

... not to mention hifi nutzs.

Anything goes for that person!

Cables, headphone coils are basically made up of 3 components:

Resistor

Inductor and

capacitor

 

Introduction of these 3 components would make the voltage / current in the headphone oscilate. As time tends to infinite (or one hour warm up ), the oscilates tends to zero.

hmm...ok i'll pretend i understood that

It's this principle that gives rise to the following argument :-

 

Q= What's the best length for a power cord?

 

Someone answered: 1.5-2m is preferred for the oscillations to settle down.

I've commented previously that Sipher's, Norther Oak's and my pair of DT880s all sounded different owing to different stage in burn-in and ownership periods.  Notably improved in the later stage is the mid range-upper bass region.  This was discovered after several months from my power buy.  This proves than some cans (like speakers) take a long time to age (like fine wine).  Some who have reliquished their 880s after that power buy may have missed hearing the finest hour of these cans.

 

According to Rober Farley (formerly Chief Technical Editor of Stereophile), even burn-in mileage can fade if an audio gear is not used for some time.

After reading a burn in thread in headfi by PinkFlyod, i decided to give it a try with my beyer 880 using foobar2k. He advised using using sine tones of very low frequency and a sweeping tone and i tried it over a period of few days while i'm out or asleep. Honestly after a few days, i noticed a increase in bass and midrange areas which was slightly lacking in this pair of cans.

 

During this period i was also fooling around with the built in eq in fb2k and i bumped the midrange and bass regions slightly. I liked what i heard through the eq. After burning in, i disabled the EQ and found that it actually sounds pretty good without EQ after all! Even when switching between different sources, i noticed improvements. And i happened to chance upon this thread again and read through Mackie's comment which proved that improvements were not psychological effects.

 

Yes, both Rameish and Mackie are right. This pair of cans is like fine wine which gets better over time. My pair of cans is about 5 months old but i never really tried any burn in tracks. 5 months later it there are still rooms for improvement!

Evil-zen: Glad to know that your patience and faith in the cans is paying off. Btw, degaussing and burning-in are equally important to maintain your cans at optimal performance. The former is more crucial when the gear has run in sufficiently.

Whaha ... i am gonna burn in more time for my DT 880 .. so far i notice it have become a little better @@@@

Btw, guys..........frequent/daily usage of your cans is the same as burning in. Some of U hear an improvement of the cans after introducing a specialized tone sweep and this is partly (if not wholly) due to demagnetization.

hmmm maybe mine is because of both reasons. last time i seldom use the beyers cause i way prefered the etys. less run in time and thus might not be fully burned in?

n3w better go play some stuffs on my sony otherwise when I am back the drivers will be stiff again
