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 never contest the primacy and originality of your experiments Geoffkait, it is all in my thread for most to read about … But here I discuss also a part of my own experiments and yours also but also others experiments from all audiophiles to partake for  the benefit of all, the copper tape is for all to bought... You own the design of the "flying saucer" not the tape...
It’s all my idea, no one else’s. You’re neither an engineer or a lawyer. My products and ideas are protected by law.
Ok Read where you give yourself the idea FREE to ALL first in 2013...I am only an audiophile who read forums about tweaks...Like this one for ALL to read...And I was not in any way here in the obligation of thanking you but I did it before today for all to read...What do you want exactly?

By the way I borrow the idea about crystals(tourmaline) from Unclestu, thanks to him, ( now deceased) on the same forum, but my experiments go far away than what he did (the cabled connected grid +S.G. is my idea)... Is my right to experiments with what he said on this forum his intellectual property? 
As I said legally I own the rights to the idea at the present time. That’s past history from 2013, my friend. Take it up with your lawyer. You have laws in your country, right? I give you only what I wish to give. 
I dont contest your right at all... I only speak about copper tape here... and I read it first on forums ...My only problem I think is I thank you for the idea...I thank you for these posts a last time and I go on with any tweaks to experiment with ...
