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 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.....

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....

More to discover
