For Your Edification and Enjoyment re "Burn In", etc.


Just published at Dagogo.com, my article "Audiophile Law: Burn In Test Redux". 

Validation of my decision ten years ago.  :)

Give me any relative good system at low price i will make it reach the stars...Even if am an average guy i love audio tough.....

I am not arrogant like audio2design with my alleged "superior knowledge" it is only elementary acoustic science directly coming from Helmholtz...I called that simple listenings experiments...

When you dont even know that "timbre" is an acoustical concept and an experience impossible to recreate without acoustical room control , when you think that "imaging" comes from the electronic design of speakers mainly.... What do you know in audio? Way less than Helmholtz for sure...

I read the thread about "imaging" and i deduced that most people dont know how to create it with 2 speakers in a room... Precise location or angle between speakers, volume, synchronisation of drivers, etc are not enough sorry...

I discovered 2 days ago the solution in a japanese research article in acoustical physics written in 2008... Understanding what imaging is finally, at least for me the beginning of an understanding, the same night i devised immediately an experiment, very simple one that recreate an imaging better than the one i already have , filling all my room ....

No it is not related to the drivers, intensity, phase, volume, orientations of the speakers mainly...they play a role for sure but NOT the main role....

You know why?

Because "imaging" is not FIRST a physical concept in engineering, it is an acoustical concept and a phenomenon in the neurophysiology of perception.... Then how to recreate a perfect imaging? It takes 2 facts put together here, one in Helmholtz acoustical physical science and the other is a law in neurophysiology of acoustic perception... You add the 2 and you have "imaging" and the way to create it in any room with any speakers...




I ask audio2design to read the article, he never reply....He bashed "audiophiles like if they all are the same idiot", he does not take anything seriously because he think he knows everything...He dont understand "timbre " i prove and verify it with a musician here and he react by accusing the musician to be a liar, the same for "imaging" and he does not even know that he dont understand these concepts ,all his arguing with another engineer whom he bashed to be an ignorant about speakers drivers illustrated this perfectly...

Anyway It takes me a few hours to translate the japanese research in an experiment which by the way was a complete immediate success...

i know how to create "imaging" with any speakers now, not by virtue of my unborn knowledge or superiority above others but ONLY because i stumble on the right paper explaining clearly what is this phenomenon exactly....And my knowledge, even if elementary of Helmholtz acoustic, helped me a lot... one +one+ two...

I will not wait for audio2design impression of the article, i am too "limited audiophile " for him to adress that with me...

Anyway i wll comment this article and my experiment on the week to come in my thread about "miracles in audio".... This experiment make me able to create my last acoustical embedding control device...

I sell nothing save creativity... Hi-fi experience cost peanuts when you know what to do....All the rest is consumerism...And boasting about pricey electronics....Hi-Fi experience is mainly working ACOUSTIC ,nothing else....




Doug this was directed at audio2design.

My point is that when doing evaluations regarding tweaks and the like  quality of the equipment is critical. You may hear it on a budget system but not to the same degree or at least not in my experience. 
Awkwardly written and more than a little deterministic in your argument.  Agreed that most tweaks are not beneficial, but alterations to the sound invariably occur, however slight they may be.  Degrees of difference do take time to experience.  As for any component changes within a system, and or two different systems used for evaluation, if at any point you can not hear a difference, stop writing and keep such inconsequential musings to yourself.

I dont know what a "tweak" is... Save for the fact that it is considered by half audiophiles useless and "snake oil", that is to say costly secondary additions to the system which basic electronic design is the most important part of the H-i-Fi experience for most...Sorry but to good electronic design which is half of the story, you must add the system tuning being the other half of audio experience...


I am sorry but controls over the 3 working dimensions of a system comes from exprienced and experimental listenings, may dont cost a dime, are not secondary additions to a system, but on the opposite the tools by which this system would work at his peak potential...








All systems at any price vibrate and ask for a control over vibrations and a control also over resonances... It is the mechanical working embedding dimension....No system at any cost can replace these controls...

All systems at any price contributed to the electrical noise floor of the house grid where they are embedded and to the noise floor of the gear with which they are connected.... All that noise ask for a minimal control over the general noise floor and not only of each piece of gear to optimize his working... No system at any cost could work without being embedded in a general electrical noise floor to which they contributed too individually.....

All systems at any price are embedded in a room where the quality of air pressure will varied zone to zone, and will ask to be controlled by the law of Helmholtz acoustic controls, the reflecting sound waves will be such reflected , absorbed such and diffused such, and will asked also to be controllled in the right balance for any system to be working at his optimal acoustical potential....These ask dor passive material acoustical control and more active one...The room is NOT a passive player....

If you think that these controls over the three embeddings working dimensions are only illusions, secondary "tweaks", snake oil, if you think that the price of a system is a warrent against vibrations, against a too high noise floor of the house grid and room, a warrent against some basic acoustical laws which are the most important laws in the perception of musical sound.... Think again...

Go from consumerism in audio magazine to basic very elementary science....Or go on with the fools calling that placebos or snake oil and warmly recommending to throw money on "upgrades" till the end of the world and the end of technology....It is called chasing the moon and chasing your tails....


My low cost system has been trasnformed by elementary science, elementary common sense, and basic listenings experiments, at low cost... It is not necessary to buy costly "tweaks", you can devise yourself all which is necessary by listenings experiments....


When the piano or complex harmony decays of harpsichord fill the room, a brass orchestra, or a choir, the sound filling the room , exceeding all limits from the speakers, with the benchmark test of a deep imaging balanced between his width and his hability to encompass the listener, when the natural timbre of instrument and voices is there and rightly perceived, the goal is reached...

Price has nothing to do with a very good experience BUT tuning, controlling the working embeddings dimensions is the ONLY key...

Nobody can make a good hi-fi experience violating mechanical physic, electrical physic and acoustical science.... Sorry...

The designer designed their good gear, they do not controls the location, the connection, the synergy with the precise other pieces of gear with which their own gear will be working, nor the noise floor created in the house/room/system and certainly no designer of any piece of gear even the speakers can act on your acoustical setting in the room at distance and in advance...


My 3 maxims are simple:

The tuning of a system is more important than the system itself...

Dont upgrade anything before embedding everything right...

ONE single straw could kill a room or ressuscitate it....So powerful is Helmholtz science....




Audio_audition, Building hundreds of rigs of all levels, from lower end HiFi (i.e. approx. 5K) to much more significant (100K) all systems have capacity to reveal changes from such things as power cords, interconnects, treating CDs (Back in the day; it was one of the very few cheap activities - I distinguish it as a treatment rather than tweak - that did result in an audible change), etc.

The system I did the testing for the current article was approx. $60K MSRP. You were happy to dismiss the article/findings with a mocking comment of the Peachtree integrated used in the first article. That turns out to be a great choice now, as persons such as your self who express skepticism about the quality of the system used in the comparisons are shown to be wrong, as several of the variables under comparison were the same in both tests. The rig used in the second article was approx. $60K. This demonstrates nicely how systems at lower MSRP can teach the audiophile the same principles as rigs at higher MSRP. One might expect that, as this is all HiFi gear. Now, if you want to talk about testing a $300 plastic fantastic system from Best Buy, all bets are off! :)

You seem to find glee in argument, even when shown to be wrong several times. I’m not interested in extending correction to you indefinitely.
