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 18 " Golden Strings" :)

I add an entire new row of 8 lava beads strings directly over my head at 2 feet from the first original row...

That was a very good idea.... The imaging is improved and now for the first time i listen to my brass ensemble for the first time, really, even if i had listen to it for the last 7 years....

How to hear the notes and the encompassing, interprenetrating radiant and agleam halos of the different brass instrument including tubas, trumpets and trombones, without loosing nor the notes neither the interprenetrating halos in a room where one of the speakers is almost on the wall and in a corner?

My soundstage is of the dimension of the room and equal out of each speakers, despite their dissymetric positioning.... :)

The speakers/ room equation, and the electrical embedding are keys....My music is no more handicapped by speakers location....

ACTIVE room controls is the way to speakers audio.... Passive treatment, except for an entirely engineered perfect room, will not do enough for compensating the room topology and the speakers locations....

I never even read information about active controls in audio thread, except active controls with electronic components...My active controls are resonators of different kind linked together with no electronic components except the Schumann generators grid...

My best....

Update after listenings....

It is insane that adding some strings to the ceilings made so much difference...

And i dont understand why one "golden Plate" on the external electrical meter do the job but 3 compress too much the sound, because i add 9 golden plates to the 7 already on the electrical central panel and the results were good without compression....

If someone know :) i wait for explanation.....

Nevermind i feel like all music is new again.... I know i repeat myself, but the last 2 years, and particularly the last years was so filled with improvements and listenings experience and discovery....

I began to feel that the acoustic science is very interesting , but i feel sound phenomena are more complex that what is teach everywhere in audio thread...

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.....
