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...

Update:

I will call "Golden Resonators" my connected 2 "golden plates" with 9 Herkimer Diamond sticks on them glued to my ceiling...They are cabled to my Shumann grid generators...


Final results after 2 days of listening are fabulous for imaging and all other counts.... An improvement in the acoustical embedding across the scale, especially an increase in depth imaging...In regular and nearfield position...Each steps on the last 2 years has been a step to a better S.Q. each time proving incrementally to me the necessity of the embeddings controls....

After my application of a fine-tuned differential compressing force on the 2 sets of 4 boxes springs on each speaker under their damping load, my mechanical embedding is very good on the isolation count and on the resonance count....

I think that with these perhaps not optimal but at least minimal embeddings controls my audio system is working on another level from his point of departure.... My goal is achieved...


My most important discovery seems to be the "Golden plates" that i use for 2 embeddings, the electrical grid and the acoustical dimension...

Remember that my acoustical embedding controls are not a "tweak" they are all connected by cables in a singular entity through my modified Schumann generators grid....

A "tweak" is a secondary addition to an audio system, my embeddings controls are the soul of my audio system, without them i would think that my audio system is perhaps not trash but under par to most hi-fi one....I dont think that at all now....It is not the best for sure that money can afford, but trust me it is enough to listen to music and forget sound limitations on any musical style , even Bruckner Symphonies...

Acoustician dont use that kind of controls in a small room, generally they advocate passive room treatment, or bass treatment or to begins with "the bass problem" and will regard me "nut" to do otherwise and to do anything like the crazy experiments i was working with....Especially if they sell something.... :)

But anyway acoustic is a far more complex field that most think it is, even for some acoustician hypnotized by linear computerized equations....Our ears, especially the biased one so to speak, cannot be reduced to simple formulas for the times being... :)


But anyway the results are there: No comparison between the same speakers, dac, and amplifier, after the implementation of the embeddings controls and after....

To this day my humble 500 dollars system is the best i listen to, even with my actual speakers that are good but not on the same level than my past bigger Tannoys Dual concentric Gold....But an embed audio system is most of the times better or on a par with many costlier one...

Upgrading is an obsessive illusion, most of the times unnecessary, especially if the audio system has never been rightfully embed...

My journey touch the end....

My wife smile saying that i lie, she wait for a new idea coming from his nut husband....But she is happy that i never spend the 15 thousand dollars i dreamed to spend for audio 7 years ago anticipating my retirement....It is no more useful .... :)

Music is music when you have it at last....

My best to all...
Update:

My new acoustical control device:

2 small Copper bowls+H.D. cabled to the Schumann Generators grid

(buddhist offering copper bowls paid a few bucks)


The 2 bowls, which had the dimension of an open palm of the hand, are located almost straight up to my ears under the ceiling, and they are connected one with the other and also directly to the 2 "golden resonators" in the center of the ceiling, connected also directly to the "Bell of bells" and like i said connected to the S.G. grid also directly...

These interconnections are very important to keep all that balanced and makes of all my "tweaks" not "tweaks" but really only ONE acoustical device control in the singular and not a sum of disparate elements...

Acoustics is not only about absorbing, reflecting, or diffusing materials, but also about putting in place an "atmospheric"  active control of the room through my active Schumann generators grid modified with "golden plates"+H.D. on each one (12 cheap chinese S.G. now )which i called the stones grid, the many resonators grids(different size and shapes), creating then ONE control device that balance all frequencies with their spectral content through an active control which is also a tagging, a kind of beacons grid, that regulate the information that the flowing waves gives to the ears....I am not a scientist anyway, i only want to understand what i create for myself that transform my audio system for a very ordinary S.Q. to another totally new S.Q. and better one at peanuts costs ...

These 2 connected copper bowl with an herkimer diamond in their center for balance produce powerful effect, audible in timbre perception and imaging at my 2 listenings position, nearfield or regular one....


I even not dreamed a month ago that i will go toward thiskind of improvement....It seems that more it is interconnected, more varied the resonators are, more the spectral content of the reflected waves of sound and the direct waves of sound are synchronised and gives me a spectacular more natural image and timbre...

Calling that a " tweak" is totally beside the point, it is not a relatively efficient SECONDARY"addition" to the audio system; it is a new way to recreate completely and reconfigure the acoustic of a small room , it is a PRIMARY fundamental tool for me without which my good system, without these acoustical, mechanical and electrical controls, is like a "trash" or some frustrating system waiting to be replace or "upgraded"....

I am very proud of my listenings experiments because no one anywhere has ever use that kind of tools it seems not at this level of improvement and at this low costs at least....

In audio experience, listenings experiments are more useful than money it seems for me at least.....


In this crumbling "old world" music help me a lot to keep my health and sanity....


My best to all....



UPDATE:

3 more small Copper bowls+H.D. cabled to the Schumann Generators grid

One is added in the middle of the pair upper my ears, and 2 one feet from the wall at the right and at the left of the 2 "golden resonators" in the middle of the room on the ceiling...


Increase in bass, and in dynamic ....In the 2 listening position...

Sometimes i ask myself is it some place to new improvement?

I know that i reach some plateau, or will reach it, my speakers has their own limited potential S.Q.

It seems that i was not there yesterday.... Perhaps i am here today?

:)

Music help me a lot to see what all can see each passing days in the world now....

I listen to my therapeutic sound cd a lot.....A great audio system is very helping on that count alone....

If not, Bach is always free therapeutic by himself.....
UPDATE:

The 9 copper bowls resonators plate...



I devise a wooden box with 9 cellular enclosure where i put 9 copper bowls+one herkimer diamond in the center of each for balance in the sound....

I put that between the speakers behind my listening position, on the wall, 2 feet from the ceiling...

Increase on all audible count: better dynamic, better timbre.....

I listen to my favorite brass ensemble, very good recording and very difficult for any audio system with non only trumpets but horn and tuba....(Empire Brass ensemble: music from  Gabrieli )

And from my 16 feet square wall come a wall of sound like i was used to but with more timbre details and more living sound....

Samething with the piano that was in my room like usual but with way more dynamic all across frequencies and a better timbre....


I was surprized but only half surprized.... :)

Surprized because i already had a more than good S.Q. but not completely surprized because these resonating copper bowls +herkimer diamond are magical.... I already had 5 separate one on my ceiling connected by cables to my Shumann generator grid with great success...

Cost: peanuts....

Results: audibly astounding.....

Any audible positive result is astounding especially at low cost...

DONT UPGRADE, if not absolutely necessary, EMBED IT ALL BEFORE ANY MOVE.....

My best to all....
A remark:

My last addition, the 9 copper bowls plate, even if located on the wall in front of the speakers behind my listening regular position( 9 feet from the speakers)AFFECT the S.Q. even in nearfield position(3 feet from the speakers)...

Then the widely held opinion that nearfield listening make unnecessary any acoustical treatment nor any active acoustical control is only that : a myth or a deceptive opinion....In a small room the acoustical embedding controls and treatment is more than important....

My best to all....
