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 : Upgrading to 26 " Golden Strings" :)

I add 6 chrysocolla and 2 big tourmaline strings....

For the reader i am not sure that it is the stones composition that plays the greatest role, except for Herkimer diamond which are powerful resonators...But these 26 strings is MY GREATEST CREATION.....

The cost is ridiculous compared to the audible effect...

Restoration of a powerful dynamic and huge encompassing powerfully dynamic soundstage at my 2 positions of listening...

5 hours ago i just said to my wife that my improvement were near the end....She never believe me for these matters... She is always right... :)

The reality is simply that the last change and increase with these 8 new strings exceed all anteriors changes in power...If i think about that perhaps it is the chrysocolla and tourmaline that explain that because lava beads are the less useful stones for sound like ruby and not great resonators ...After gluing  my first strings with Herkimer diamonds which was very powerful change, the addition of lava beads strings help and increase thing but in a lesser way than with the chrysocolla and tourmaline and these stones are very powerful in sound audio, that was already known by me....Then perhaps their internal structure and their resonant capacity plays a role like for H.D.

Now it is probably  the END of this thread....

I dont know how to increase these results and i dont give a dam now.... I only want to listen music.....

My best.....




UPDATE : Upgrading to 28 " Golden Strings" 4 with 2 feet lenght

It seems my thread about embeddings is not closing yet... :)

I sleep very well but not much...

I decide to add to the 13 inches grid of 26 Golden strings, 2 more longer strings... I use 2 tourmaline strings already in place but they were in fact necklace, i open them and gain 2 feet strings instead of a double 13 inches.... I remember that i had bought 2 other necklaces of tourmaline.... I open them and now i glued to the ceiling beside the golden strings grid of 13 inches the 4 longer strings of tourmaline...

The upgrade to 28 golden strings now was really something....(22 of 13 inches lenght and 4 of 2 feet lenght)

More bass, more encompassing dynamical sounds....In my 2 positions nearfield and regular...

There is no more relation between this audio system when i bought it and put it in a non controlled acoustic room and in a almost non controlled electrcial grid and the situation now...

I will add photos soon....

My best...

I hope i will not have other ideas for a week or more.... I want to only listen my music now....

UPDATE : Upgrading to 30 " Golden Strings" 6 black tourmaline strings with 2 feet lenght...

i was so amazed by the last 2 feet strings, i go in my basement, pich the last 2 necklaces and transform these necklace that were glued on my principal electrical line in "strings" of 2 feet... Anyway with 16 " golden plates" my central electrical panel is already under controls...

And guess what?

Adding these 2 beside the other 2, 3 on each side of the 3 rows of 13 inches 24 "golden strings "with H. D. and the one with lava beads, makes the bass more precise and more powerful.... Imaging better....

I think i am done or nuts, but in the 2 cases i am happy...

I read Floyd Toole, one of the foremost authority in acoustic, there is nothing in his science about active non electronic room controls with passive and active interlinked Schumann generator and my grid of "golden strings"...

Acoustic seems to be waves to passively interact with, the guide and foremost law being the equations of their very linear habits.... :)

These laws were most useful for the creation of very large musical Hall after the Greek theater inspiration...Small room are other best completely to be tamed....

But waves are very intelligent indeed, non linear in their working, and can be made more "wise", what i called an "informed wave" by active feed back with device like a grid of S.G. and grid of resonators and grid of "strings"...

The brain need fixed grid points in the flowing waves to catch the flow and recreate the recording acoustic and differentiate it from the room acoustic at the same time...The brain wait for cues....The "golden strings" gives them these cues in an array of tags informing the conflicting direct and indirect waves how to walk together in rythm (time synchronisation) so to speak.......Fourier analysis easier then for the computing brain...

I dont know if i am nuts but my audio system is the best i ever had, no comparison, and the best i ever listen to....Not bad for a 500 dollars used equipment well choosen tough....

All my 6 headphones sound like trash and i dont listen to them for music...
