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...

There exist at minimum 3 embeddings of an audio systems...

But one of them has 2 side:
the passive room treatment with absorbent or reflective materials,
and the active acoustical space modifications of the rooms...

They are not synonymous at all...They are not the same thing even if they play a role in the modification of the acoustic...

I use the "singing" reflectors and the Helmholtz resonators in a way very complementary to the passive room treatment but they are not the same thing...They are used in a more active way because of the importance of the locations , height, and orientations in the room...

The modified Schumann Generator are another powerful active way to modify the acoustical space...The more active and impactful one in his effects...

Then keep in mind when we speak about three embeddings:

1-The mechanical environment of each electronic component (vibrations-resonances controls)

2-The electrical grid of the room and of the house

3a-the passive room treatment with materials
3b-the active acoustical space modifications


" We must keep the number of distinctions smaller than the number of working neurons" -Groucho Marx
The electrical grid of the house is so powerful destroyer of the audio system S.Q. I am baffled...

I just put some small "golden" plate on another telephone box in the basement (I already was taken care of the other 2)...Incredible increase in dynamics and clarity....This comes after I just said to my wife that now for sure my audio system is at his peak working level, and we must wait for nothing of great magnitude about S.Q. :)


The audible effect of this minor change is astounding....Muddy Waters "folk singer" an audiophile cd with unmistakable recording quality makes me able to seize immediately the magnitude of the improvement....


" Never say never except to your wife" - Groucho Marx
If I had the money I would buy a big lithium battery, I will tweak it with my golden plates to decrease his noise level, and i am sure that the results would be better off the electrical grid...


Most people dont know the negative powerful impact of the electrical grid of the house.... They have never listened to their system peak potential S.Q. and they want to upgrade their electronic components with more costly one....How sad!
Update about telephone cables box:

My internet provider is the telephone bell company...

Putting more "golden" plates on these 3 boxes and the wall unused plugs linked to these boxes makes a big differences...It was immediately noticeable, but after hours of music, I know for sure because plenty of details are new on some files...


Really the 4 methods linked to my 3 embeddings are the ONLY way to give yourself a great audiophile experience....

Unbeknownst to us, the electrical grid is the great destroyer of the sound....Discussing amplifier choices or tastes or even dac choices, after that seems preposterous, because the difference between electronic components is most of the times insignificant,compared to decreasing the noise floor of the electrical grid, especially if these electronic components are on the same rung of the scale price...Even the difference between speakers can be critically assessed only in a treated room and in an acoustically modified space ( remember that this a 2 different things)...How is the sound of a speaker is a question that has no meaning except for the designer out of a specific room....


I am flabbergast another time with my last "golden" plate use....And by this disruptive power of the electrical grid and the high level of the noise floor...I know that 6 months ago for example, but i am flabbergast anyway each times this noise floor is decreased...Imagine those people who believes all is right in their audio kingdom because of their new amplifier or dac; for sure all is better with a better piece of E.C. but at the end it is a veiled costly illusion that hide the essential ... :) I cannot laugh because I was one of them, and I am again one of them because I myself underestimated the high noise floor of my electrical grid to this day....I can smile but I cannot laugh indeed... :)


A big lithium battery for the dac and the amplifier will cost big money.... I dont have this money then i had no other choice now to add new "golden" plates....

I had a new idea to makes them more powerful ….But I must wait from China.... :)

The home telephone system, land line or cellphone, is not connected to the audio system AC power lines. It looks like you’ve unwittingly stumbled onto embedding no. 4 - Information fields. 😬 The most insidious and rampant embedding of them all! You can’t escape it and you can’t detect it. They’re coming in through the TV, too, like the little girl in the movie The Ring. Be afraid, be very afraid!

It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man’s fears and the summit of his knowledge. This is the dimension of imagination.
