Miracles in Audio, by luck, by good choices,by design or by tweaking...


I owned a low cost headphone for many years, the Fostex TH7B, first version( a new one close version exist Fostex TH7BK), semi-open headphone...I was never completely satisfied by any headphones I ever owned: Hifiman 400, Stax basic lamda, Stax 5 gold,Akg 340,Akg 701, beyerdynamic 990, and T150... Because in each of them with all their qualities I never listen to at the same times, a confortable headphone with natural timbre and voicing, with a good imaging and a realistic soundstage(not too close to my ears)...


For the last days I tweaked this Fostex, to damp his internal resonance I used sorbothane, I put some shungite stones at the exterior part of the cups and I use some Herkimer diamond in the interior pads( 3 at 120 degree) … Now this low cost headphones crush all my others if I sum all his qualities... For example his mids and voicing cannot beat the AKG 340 but among all my other headphones it is the best that is near that mids and it is more confortable, and with longer cable than the 340...His imaging is better and more realistic than the 340 etc etc...It is the same if I compare with the others...


His most important qualities is natural timbre and clear imaging,very precise pinned point accuracy and natural, so clear it crush for that ALL the others to dust...In the French audio circle the reviews were more than very positive few years ago...Diapason d’or and choc Classica...I am not the only one impressed buy the ratio quality/price... But remember that thesae reviewers dont tweak their headphone...The difference between before and after the tweaks are staggering...


Yes Miracles happens in Audio: cost is under 100 American dollars... Few years ago they cost me 50 bucks new... I never dreamed that I will go back to headphones...


I will enjoy your miracles stories of any kind ….My best to all...

It is amazing how good a very well designed dac is for retrieving and translating details to a good amplifier, and how good is a good one for transmiting that information to the speakers...How good, good speakers are is also surprizing....

I can say that because in my own experience , my dac and amplifier and speakers has amazed me totally in the last weeks...

Why?


Because when I bought them, these 3 actual components few years ago, I was not so flabbergasted by them like today....The reason is simple, without the controls of their 3 embeddings these 3 E.C. worked way under their own potentials....


All these last acoustical active tweaks controls propelled them to an another level....

The acoustician know much more about Hi-Fi S.Q. than the electronical engineer indeed....This is my motto.....

Your ears then know much more than a measuring device....

But only a fool will put aside the experience of the electronic engineer for sure…. But in life there exist priorities....That is my point....


Acoustics of the room is the most important feature of an audio system, especially not only the passive controlling ways, but mostly the much less known active controlling ways....





UPDATE: 10 new brass cap cone 3/8 inch distributed in horizontal and a vertical grid of bells cones...

I replace all tourmaline stones center with Herkimer diamonds... They are more powerful for clarity....

The red tourmaline push "heavy meat around the bones", but the H.D. gives me more clarity in the higher spectrum... each stones can be used with success relatively to your room and particular audio system....


In general Herkimer diamond even the micro and nano one are very powerful stones.... The most powerful with the shungite and very complementary...
Update:

The sound was too bended towards the higher frequencies... I glued a red tourmaline chunk in the center and on top of it a H.D. on 2 of the bell cones in my grid and that was better.... Conclusion: experiment and listen....
In the last week I refined the "grid of cones bells" with the "crystal cannons" idea and also by adding Herkimer diamonds of different size to the red tourmaline stones at the center of the big brass cones 3/8 inch that are horizontally located in front of me at my right on the wall and near the ceiling, and also vertically near the right speakers on the wall …

These "grid of cones bells"
work like some beacons on the flowing waves resulting from the interaction of the direct sound from the speakers and the refracted sound coming from the walls, and give to the ears some fixed points to make easier his Fourier analysis of the sound …

The reader must understand that the best improvement come with experiments and listening….The big idea dont come in one fell swoop perfect and without defect....All my ideas are complementing one another and compensating one another.... The end result for example tonight is out of this world in clarity compared to the past days or months... I never listen to a better sound in near listening and in a regular listening position on all counts: bass, higher clear frequencies, details, dynamic, soundstage more wide, imaging more precise....


These improvements are not free and comme with my cumulating experience for example with the properties of the different materials I use...

This evening I also create a new idea , a very simple one....I will speak about it later.... Because it is powerful, easy to made, but almost all people here must think that I am crazy.... And this is crazier....

Silence in this thread is a testimony for the total ignorance of their own potential and lack of confidence of people in their own listening power....


I know, I was like that 7 years ago, dreaming to buy costly gear to create Hi-Fi experience, trusting all this marketing lines about audio...

Lack of money luckily makes me more creative and at the end not only successful but more happy...I dream sometimes again to buy the costly Berning ZOTL, but like someone who already owns the best car in America dream sometimes to buy a Ferrari....It is no more a frustration, only a curiosity.... :)



My last experiment is a success but I cannot understand why... :)

Sometimes the things I invent makes sense, sometimes not, but never mind if they work....

I linked with 2 thin copper band tape (2 feet long) all 5 big cones3/8 inch in my 2 main grids of cone bells , the one vertically and the one horizontally... Result: an imaging and a clarity way better....Spectacular and absolutely surprizing...I will take a photo in few days and put it in my"virtual system" page

This cost me nothing and gives me, in nearfield and regular position, an imaging better than what I ever experienced in the past days ...


Hi-Fi cost nothing.....Only listening and acoustical imagination and creativity.... Trust your ears not the ads....


And if your amplifier is good already, trust me, he's better than anything you ever thought of him.... Same  about your dac…. Embed it and dont buy anything before that....
