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 forgot to mention a better perception of the timbre and more natural one with an increased imaging really.......

This " Twin fan combing sound" is on par with my "golden plate" creation....

Viva Herkimer diamond !

What a day!

UPDATE:

"TWIN FANS combing sound room enhancer"

My last idea was to add a third fan near my right speakers, the enclosure at the level of the tweeter and bass driver... ( with an herkimer diamond stick in the center of the enclosure)

Wow a better mid bass and bass this times....But the improvement is at all frequencies like with the 2 first fans with more in the highs for the 2 first one and in the bass with the third one.... No degradation on all counts with the H.D. in the center of the enclosures... 

These 3 fans are my best ideas with the "golden plates" and with many others , each controls tweaks add something, but some are near miraculous...

These fans are astounding controls means for no cost or almost...


My inspiration comes from the Shakti hallograph, a kind of wooden 3 wood rays trident that we must put behind the speakers...My fans work in front of the speakers against the opposite wall, metal enclosure at the height of the drivers.... :)

I dont have the 1000 US dollars for that Shakti thing.... But i have 3 unused fans with metal circled enclosure that surely will finely ethereally COMB also the sound of the speakers like a comb will comb the ethereal hair of a beautiful woman....


Conclusion: i even doubt that the Hallograph will do best than my fans.... So good they are.....

UPDATE

"Twin fans combing sound room enhancer"

I put the plumber caps 3/4 inches in the center of the fans and glued the mini stick herkimer diamond in them instead of gluing them directly in the center of the fans...

Great results strenghtening the mids frequencies and imaging without any loss on all other frequencies...

The twin fans (i use 3 in fact in my room) are ridiculous cost like any of my homemade controls means and gives me astonishing results....

Use your ears and you will save much money.... :) Alas! people are most of the times more confident in the price of the gear than on their own ears....For me only my ears judgment count, and all my homemade device controls cost peanuts....

My goal was and is always to create Hi-Fi  experience for the poors.... The only solution is a rightful triple embeddings of the gear.....

Never go with the crowds, especially in audio matters.....

The addition of these 3 brass plumbers caps on the plastic center round plate of the fans where i put the herkimer diamonds sticks has an incredible effect...

My invisible and silent readers, please think now about WHY only 3 pieces of 3/4 inch plumber brass cap (some kind of large cone bells) can produce so powerful sound correction?

These are part of my homemade active acoustical embeddings controls saga....
