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...

Where is geoffkait?

Is he in good health?

He was one of the few visitors here....

He was nowhere to be heard of for the last 3 weeks...

I hope all is right for him.... With this pandemic....


Update

"Twin fans combing sound room enhancer"

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....
Hey magister!
Wanted to report that I just took my first dive into the placebo pool with some very “quieting” hunks of Shungite
This stuff is very weird. Kind of tingly when I hold several pieces in my hands.
Is this stuff completely benign for humans?
It sure does deepen the black levels on both audio and video.

First "placebos" is not an explanation for increase positive effects step by step experiments resulting in many positive S.Q. for 2 years... When a pills increase his effects with time and dosage, it is no more a placebo...

Second read about shungite for his non negative effect on health...

Third for an improved effect in audio put some copper tape on one side of the shungite plate, i call that " a golden plate" and put it near , power supply, or the electrical central panel, or anywhere in upstream of the audio system but NOT near the dac,or the amplifier....( the copper side always external) You can try it behind the speakers electronics or cables....There will be a lowering of the noise floor that i cannot explain at low cost....

I am in the business to give to myself and others that dont have the money the Hi-Fi experience, mainly with homemade low cost methods that improve the mechanical (resonance-vibrations) embeddings of an audio system, the electrical embeddings by lowering the noise floor of the house, and the acoustical atmosphere of a room not only with passive materials but with active methods...All my ideas are free to use and experiment with....

Even if my system look like a joke, it is not one. trust me....I dont need to upgrade it at all, then at least he is good....
Most people dont know how to embed their audio system and know only one way to create a better S.Q. : very costly upgrading.... I know better and i want to give that advice to all: embedding an audio system is the KEY to a great S. Q.

Never upgrade BEFORE embedding what you already owns.....Then you will listen to the true potential of what you already have in hands BEFORE changing it at higher cost, half of the times with no more complete satisfaction....



My best to you....


Correction error:

 On the " twins fans" my brass cap plumbers are 1/4 inch not 3/4 inch.... Sorry...
