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 4 :

I decide to add an Herkimer Diamond to the one already there on the Black USB S.G.

Godammit! They work well with the golden plate on the S.G.

Improve details without being harsh at all because of the shungite+copper….

Absolutely NO compressed  effect,(because the H.D balancing frequencies effect), zero harshness, better natural timbre, natural details and organic imaging....

I dont know but my best upgrading improvement except for the  20 "golden" plates everywhere in my house (yes I count and it is not 16 like I said) is this centered S.G., located in between my brain and the gear, with 2 Herkimer diamonds and a small "golden" plate (Shungite+ copper tape)...

I will say something to be clearly understood...

Yes Schumann generator has an impactful audible effect, if not audible by you, i suggest that your room acoustic is lacking in a way or another or your audio system is not in his optimal shape at all ,or perhaps the two ...

But, I dont have experienced the effect of one S.G. to be so amazing at first, only there, audible, but subtle tough positive yes...( I owns 4 cheap Chinese usb S.G. and 2 cheap one with power supply, and finally I bought the costlier last one around 50 dollars)… But when I added these 6 cheap one that I modified with stones and crystals links (shungite,tourmaline, agate, H.D. or jasper etc) then the effect was more audible than ever and begins to be amazing...

The S.G. for me is a transmitter of the stones acoustical enhancing and electro cleaning power...His astounding effect is linked to the stones qualities...By himself the S.G. is good audiophile product, but modified like mine they are absolutely amazing and transform the audio system and the room (if the room is already good and ready to be transformed for sure)...


The last one, better located, and more precise and efficient with the shungite+copper+2H.D. this one was more than amazing...

One important fact ….

If I use only H.D. or quartz anywhere in a system, the system will develop the tendency to be too harsh, and there will be a degradation of the timbre of instrument...(except perhaps on the breaker panel where this will be less negative)

If I use only nude shungite anywhere in an audio system(except perhaps on the breaker panel where this will be less negative) this will induce a compression of the dynamic and a degradation of the timbre instrument  in an another direction than with the quartz...



If I couple the shungite (with copper tape on one side) with this powerful doubled terminated quartz (the Herkimer diamond) I balance the effect of the powerful Shungite… The net results audio wise is without negative....



All other crystals and stones has their own properties and qualities, but the 2 more powerful are the shungite and the H.D.
Some being less potent has tough  some natural equilibrate positive effects : tourmaline... We can use tourmaline  in many location with great benefits...

I just reinstalled one Mat and 4 Cards in the system after giving them two days in the breaker box to “charge” them up, as it were, as suggested in the threads on such products. The charged up Mat went under the Sony Walkman CD player, which is on a special spring based iso stand, Fr circa 2 Hz. 

Two Cards went on my Sony DMR-700v headphones and the other two Cards went on my two BLACK USB Schumann devices. I also attached a Golden shungite plate to each BLACK USB device for good measure. The BLACK USB devices are isolated mechanically via suspension and are located at height of 60 inches. Better safe than sorry. 

I should mention I also recently treated all contacts of the BLACK USB device including wall outlet with Total Contact, the Graphene contact enhancer, so those contacts are still breaking in. Nevertheless all these recent changes have wrought a big boost in dimensionality, dynamics, resolution and naturalness. I shan’t attempt to ascribe effect to causes however, although the charging of the Mat was an obvious big effect.

Add some Herkimer diamond to the golden plate Geoffkait and compare that with other tweaks....You perhaps will be surprized?
