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...

Magister: I always speak ironically about placebos. Making fun of the concept is my most effective tactic.
When I was about 20+ yrs old, I was talking with my father while standing by our dining table—which was all decked out for the holidays with candles & ribbons & decorations & munchies, including a big bowl of mixed nuts in-the-shell. I had a walnut in my hand and was making a dog’s breakfast out of getting inside the shell. My dad grabs two walnuts in both hands, squeeze once, both nuts lay open like brains. I was so pissed. He had let me grow to manhood without showing me a trick that I could have wowed all the neighborhood kids with.
Squeeze them together against one another. Simple. Just like politics.

In my estimation, the untreated pyramids attracted EMR for adsorption affecting the adjacent cable for up to a meter. Assuming the copper rejects or reflects the EMR, the only shungite surface in play is the one sandwiched on top of the cable or Shumann generator, or connection.
Ok this explanation is only half of the story....

The "golden plates" act also like a passive filtering device and not only like a passive shield, all along their location in the grid...

Experiment:

Take an agate, a black tourmaline, or a big herkimer diamond or a chunk of ordinary quartz....Put one of them glued to this golden pyramid on the connector...

You will observe a kind of filtration by the structure of the minerals working on some different frequencies linked to the stone chosen... ....

An agate will give a more expressive mid frequencies and some bass, a quartz will give more in the high frequencies, an herkimer diamond will do like the quartz but better.... The black tourmaline will act in a little higher level of frequencies than the agate and may improve on it....

You can try Kambaba jasper, that will work on the imaging....i will not gives all possible experiments.... I have try many....

My point is: these shungite+copper or "golden plate" does not only shield but filter in some way the line, decreasing the noise floor level by some kind of filtration with an effect that change if we change the stone....


then : shungite+copper+ herkimer diamond or tourmaline or agate etc =  some shielding and some filtration....

I am sure now to be treated like a nut against an another nut..... :)

UPDATE : Upgrading the " The Golden Strings"

I decide to add 2 other golden strings with slightly bigger Herkimer diamonds (24 on each strip of 13 inches), i glued them to the cieiling between the other 2 and i connect them all with one another .... Now all is connected by the Bell of Bells to the Schumann generators grid of ten...

Guess what?

Yes increase in the higher frequencies extension and bigger soundstage.... Now i think there is no more improvement possible with these for the time being...  :)   ( my wife smile with scepticism at my denegation)

My 4 "Golden Strings" are really what moves my other acoustical controls device on another level....

I dont know what to say...

NO my friends, HI-FI experience dont cost money, only creativity.....And simple works, but very  attentive listenings....

Dont listen to reviewers and dont trust them, you only need good but not necessarily costly gear, only good one.... The rest is more important than electronic design: taking care of their embeddings, especially the acoustical one.... And most of the times passive materials treatment of a room will not be enough to free the sound.... ACTIVE CONTROL is the way....

Thanks to all....

UPDATE : Upgrading the " Seven Golden Strings"

I add 3 strings of lava beads because i was lacking of strings of tourmaline to the 4 "golden strings". That work fine but i will replace it someday with strings of tourmaline... These black lava bead strings will not be connected because lava bead can be destructive of the sound if too much near the gear...I use it to isolate normally from EMR on the electrical grid...They have an effect similar to brute quartz but worst , like a too strong cleaner.... :)

But on the ceiling with the other strings they serve as resonant fixed points beacons grid to create an "informed wave" and create a better synchronisation between the waves for the Brain Fourier analysis computer...

I add 2 agate on the coipper string of 2 "golden strings" to give more mid-bass body and that worked immediately....around 140 Herkimer diamonds on 4 strings connected to the S,G. grid create an emphasis slightly on the expansive higher frequencies.... Then the addition of 2 banded agate give an equilibrium that was perfect... I add a few gram chunk of shungite on the Bell of Bells for the same reason.... That was a success.... I know what i do with stones after all these years... Each one is a unique resonator or filter or the 2....

Even my wife that says all day that i am nut admit that the sound is extraordinary and she does not listen to music et dont give a dam about that..... :)
