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...

There is no link, the plates are a homemade easy tweak to make : Shungite plate + a tin copper foil on one side...I called that "golden" plate...

My best to you and thanks for your caring interest...


You can see some photos in "my virtual systems" section....

In my last upgrade post I forget to add to the list this spectacular changes when I put tiny quartz stick on the arms level of the tone controls of my Sansui AU 7700 and on the arms level of the loudness, muting, and mode controls...This simple tweak made a big impact indeed...With the addition of the last 2 big plates on the router (3 now) and on the breaker panels (6 now) it is the last necessary addition I think, the audio system begins to settle around his highest potentials on all counts...

I reintroduce some thinner golden plates on some S.G. with success...The problem, if there is one, is to always balance the plates with tourmaline or H.D. for the best S.Q. and use a not too big thin shungite plate for cell phone....


The proof for me is there, we dont know how much good any relatively good audio system we owns is already, and we spend big money to upgrading it by changing it, instead of the necessary simple modifications. I repeat that because nobody insist on this fundamental information and fact...It is not always a so called "better electronic component " that can transform the audio system, it is simply addressing the vibrations-resonance problems, the acoustical room treatment, the electrical embeddings of the room and the house, and some other simple and homemade tweaks...


Now I will wait for some of you to confirm some of  my simple experiments.....

I read one of the first positive experiment confirmation with my golden plate on another thread... I am glad that someone report something favorable about my free product and creation...But alas! none here for the time being... :)

For me for the last weeks, with all these experiments ongoing, the audible upgrade is in his last stage...If you had immersive imaging + natural timbre of instrument +dynamic, the only future upgradings will be minor ameliorations that could seems important for sure, any positive minor change is a treasure for an audiophile, but minor changes tough compared to where I come from...

My best to silent Geoffkait, and other ghosts, inhabiting this thread...

My new addition, well, one of my new additions, is Double-sided adhesive *highly conductive* metal-cloth tape. The tape is copper/nickel + high-conductivity acrylic. A Big roll, free shipping from China, from eBay. I lost confidence in the adhesive backing that comes with the shungite plates. Of course, the adhesive for the shungite needs to be highly conductive. In any case, the metal cloth tape seems to better than the rubbery adhesive - I.e., more conductive. I removed the original adhesive with isopropyl alcohol, then apply a one-inch section of tape. Voila!

My new configuration for 2 BLACK Schumann doohickies is one eCard on one side, one shungite plate with Flying Saucer on the other side, using the metal-cloth tape for attaching to the SR. All isolated with 1 Hz suspension. I’m also using stacked eCards, two per side, all of which are charged for 2 days on breaker box, on my Sony MDR-700v headphones. As usual, I have a bunch of simultaneous experiments going on so I’m not 100%, maybe only 92%.

I return you now to your regular channels.

Thanks very much for these informative experiments and recommendations ….I will try this tape... Thanks...My best to you...


I just order one roll of the tape... :)


A remark Geoffkait:  Perhaps you must try an Herkimer diamond with the plate or a tourmaline for balancing the effect...
