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...

Mr. Owen’s formula is dynamite. You are in for a treat, I predict. Are you getting the PVA mix?
All the best to you.
I will wait for the graphene+mica fluid.... I want to apply directly on the shungite side of my plate....I will experiment with the pva mix later.... By the way where do you buy the pva?
I was actually referring to Mr. Owen's mix. He makes PVA mica/graphene mix and PU mica/graphene mix. The one to get is the PVA mix.

You can get PVA woodworking glue at any hardware store.

Do I need the glue for the graphene+ mica liquid?

I was thinking that the glue would be necessary with the material form of graphene not the fluid? am I wright?
No, Mr. Owen's PVA mix already has the PVA in the mix. The first lot I got from him was an alcohol blend, with no PVA. But it rubbed off much too easily. He solved this by making the PVA mix. By then I had already made my own PVA mix from the original mix.
