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...

UPDATE about the "Connected cones bells grids"


This is my latest homemade tweaks and I must say very amazing...
How do we define "naturalness" in S.Q. ?

Naturalness is elusive like many audio sensation, but anyway a real sensation...This sensation gives you the final taste, the taste of the real presence, this taste is a drug with no possible detoxification... This is the ultimate S.Q.....

This is an "elusive" quality, because you can think that you have it without having it really in the flesh...The sign and symptom of his actuality is some connection with the music that cannot be severed....The feeling that it cannot be better.... But is it the end? Geoffkait says that we are most of the times always in some base camp all along the road and not on the apex of the mountain....At first I was thinking that he was mocking me, but I now think that it was only clue...     :)


How in the world connecting with 2 bands of 2 feet copper tape, 2 grids of 5 cones bells, can gives me that quality more than any other controls tweaks?


I dont know, perhaps this modification come after a number of other cumulative changes and it reach a threshold...( for example the 7 "golden plates" I added around my computer, one week ago, were a big step but not enough to gives me on their own that "naturalness")


Trust your ears and listen, go with them, because no others will transform you for the better except those 2 friends and magical mentors ….

UPDATE: "doubly connected cone bells grids"

I added a copper tape ribbon to the first one linking the 5 crystals cannon in each grid the horizontal and the vertical one...More realism and more presence and more details, more dynamic...I will post a new photo in the next day in my "virtual system" page...

After the "golden plates", the modified Schumann generators, the connected crystals cannons, the cones bells grids, the bells of bells, the stones grid, the multiple resonators, the Helmholtz bottles, my delirium touch the end of my journey I think....

How far can we go with a better sound without changing an electronic component?

I never imagine that my dac, amp, and speakers would sound so good ever in my life when I bought them....I was dreaming to upgrade them few weeks after buying them because all forums and thread says the same thing like a chorus, the costly it gets the better it is.... This is more than false, it is a myth created by advertising and ignorance about the three embeddings necessities in any audio serious endeavour....For sure my system does not sound like a million bucks system, but for the price Boy! not so far behind, and way more closer than you think.... And I know that my photos look like trash..... :) 

My goal is in my own hands and I touch it.... Homemade low cost methods are all that is necessary to afford Hi-Fi....

My best to all....

UPDATE: "connected cones bells grids"


The increased details made me connecting them all with the copper tape....The clarity increase....


No explanation comes to my mind.... A sound wave affected by connected brass cones? Why?


Never mind physics !.....Viva music! .... But if someone has the beginning of an idea he is welcome …. :)


I will repeat the only idea I have and this is a metaphor :

These connected "grids 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 set of fixed points to make easier his Fourier analysis of the sound …



One thing is evident: All instruments are way more distinctive in the Bach brandebourgeois concertos....And it is not my first listening session with this file to say the least....

UPDATE: "connected cones bells grids"

I added my computer screen with his 2 grids of cones bells on each side to the connected series of grids in my room....

Same upgrading clarity effect....

WOW !

The mystery is astonishing indeed... Why thin copper tape around cones bells can produce this powerful clarification of the imaging in the first place? Particularly spectacular in nearfield listening but also in regular position...


This event is a surprize at the moment I was thinking that my audio experiments journey was ending..... :)



Dear reader remember this: the acoustical embeddings is the most important fact in audio.....Most of us dont know that...

The proof is simple.... For example, I know very well that some cables sound very different with one another....But the difference is minute compared to any changing controls in the 3 embeddings.... I then conclude with all these discussions about cables that people dont know much in Audio improvement at all because their fixation in favor or against  changing cables is an indication of their own limitations....The rightful embeddings exceed any changes of cables, or often even of gear....And the acoustical embeddings is so powerful that it is only on par with the exchange of a low piece of gear  to a very refine one....Nothing less....

An important note about my last experiments:

The reader must remember that my audio system is very sensible to changes because it is already heavily and rightfully embedded to some degree... Then the audible effects I described will vary from one audio system to another.... But the reader must begins by the simplest embeddings: the mechanical resonance controls.... After that he can try the electrical house controls embeddings step by step and the acoustical one....

The acoustical embeddings is the more complex for me, because there is a passive way, the classical way to use materials to absorb or reflect the sound, but the active way are more powerful( Helmholtz bottles, modified Schumann Generators, various resonators, bell of bells, grid of connected bell cones of different size, stones and crystals) and also necessary to transform ANY room....For the electrical embeddings controls I use mostly stones and crystals and my 30 marvellous "golden plate" around all electrical utility, be it a router, a wall plug, or a conditioner, the computer, the phone box, the electrical panels etc....
