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...

Sounds like wonderful dinner music.
Okay Professor, let's hear your explanation about room resonators with headphones.
Well mahgister, it appears no answer is forthcoming from geoffkait.
How will I ever sleep tonight?
Oh, I know how! I don’t care....
Have a good night, my friend.
I think that Geoff is sulking us... Good night...


P.s. I would have liked to know his explanation tough...
whostolethebatmobile,

Do you have a recommendation on the source of shungite tile and ataxite stone to try on my mains breaker?
thanks.
Forget Ataxite for now... it is too easy to damage the sound using it...Use shungite tiles on the top of the main central panel not in contact with the breakers (be cautious not to play with the panel, it is dangerous) on top of the metal case of the panel ou fixed under it or on the side... Use also black tourmaline 2 big chunks between 100 or 200 grams (China providers on ebay or aliexpress)...For the source of shungite use " shungite club"  on Ebay…. Buy shungite ONLY from Russia or Ukraine... I had three tiles and wait for a fourth to put there with great results...
