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...

I spent about $800-850 to procure the above.
It is cumulative in that, yes, more than one adds more realism to the sound. You can hear such detail and even ambiance in the room where the recording was made becomes very apparent.
The recordings sound believable, very authentic, because now the harmonic details have emerged which were always there but were not readily perceivable. I attribute this because of resonance applied by way of low frequency field "tuning", if you will, the audio signal in the system.

Some examples of my experiments:

Tourmaline will clarify the frequencies (i work mainly with the black varieties because of lowest price)...

Chrysocolla will open the imaging....Kambaba jasper also but in a more subtle manner...

Shungite will gives body to the sound but too much can be detrimental and generally shungite works best near power source, power cord, cables … Do not put shungite on top of the gear..

Nephrite add a gentle velvet texture to the sound...It is difficult sometimes to describe with words these effect of stones.

Herkimer diamond work in enhancing the effect of  any stones or crystals and clarify also the frequencies but work really best coupled to another stones...

Agate and amethyst are also good but less powerful in the working than most of the stones i already mentioned...
Banded Agate and Madagascar agate touch the body of the sound, amethyst work more his hues colored timbre...


Varieties of quartz works powerfully but better coupled with other stones...They work from the high frequencies toward lows...(agate works more from lows to mids on the coloration timbre)

Lava beads are very powerful and works always  with the main power source if this source is very noisy ( lava are not so good on the gear)...But lava works better coupled with another stones to mitigate his powerful bleaching effect, for example with shungite or with agate...

It is very interesting to me because connected to my grid of cabled stones and crystals, I had already connected 5 Shumann Generator, that I located at varied spots and height with stones on them and also linked together, even with some small vertical antennas... The effect were an enhancement of the imaging and timbre of instrument... The S.G. produce a low frequency which is the very resonance frequencies of the atmosphere of the earth, and it seems that this broadcasting frequency tuned the electro-magnetic field of the room,and also broadcast the filtering particular effect of each stones coupled with the S.G.

I am very interested by electraclear model that is low cost... I cannot afford this same amount of money (800) for now to my audio system... But I am not frustrated at all because I think I realized something similar, homemade, if I read the description of the effects, with my modified S.G., which are embedded in a connected batteries powered grid of stones... Each stones is part of a filtering equation with the others, they are all linked and act like a complex passive filter...Coherence systems use an algorithm that program an active filtering of the noise level...

One day I must re-installed all my grid, because I discover better product to glued the stones and cable (magic nano tape) and I discover that the best cable for the stones are not the regular one even thin, but the telephone cable, which is hairlike thin...Probably my grid would be more powerful if I recreate it with all that I know now... But I discover all that, one stone at a time, small idea after another, than mostly improvising all that with the judgement of my 2 ears...

I ask to myself now this question, how the modulated algorythm that is used by Coherence Systems symphony to tuned the audio system act with the S.G. in the equation...

Perhaps Bemused you will buy a chineese cheap usb version for 10 bucks of the S. G. and try that ?

It will be an interesting experiment no?
