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 will give an example of the LISTENER ENVELOPMENT concept and acoustical experience (LEV) for any audio system to test yourself...

It take a great control of the room to hear this :

Threepenny opera of Kurt Weill with Lotte Lenya 1958 version :

https://www.amazon.com/Weill-Threepenny-Opera-Kurt/dp/B0000026HI/ref=pd_sbs_2?pd_rd_w=6koxC&pf_r...

listen side no 15, The procurer ballad, 4minute 38 seconds:

In my room the male voice sound in my left ear like with an headphone, same for the feminine voice singing in my right ear at the same moment, the 2 voices seems coming from behind me, opposite to the speakers locations and the orchestra are in front of me behind the actual speakers, at 8 feet distance, filling all my wall between the speakers but behind this wall.... i have the impression of 2 other virtual speakers behind each side of my ears.... Like if there are 4 speakers in my room... There are many sides of this cd that give the same effect not only this 15th side...But this one is particularly spectacular...You will undestand why i trash my 7 headphones in a drawer and will never bought none other....

This is in my regular sitting position...

It is no more true in nearfield listening....Where the sound seems a "bit" more detailed but is less livelier or less natural and sound exactly like in an headphone but better with my speakers/room... Passive and active room controls work EVEN for near listening, contrary to a false popular misunderstanding of the way and of extraordinary speed of sound crossing the room and affecting it, in relation with the 80 milliseconds of critical analysis time treatment from the brain to make sense of these wavefronts travelling near 80 times per second in my room...Each wavefront is a bunch of frequencies travelling together...

It is an example of ACTIVE room control of the "listener envelopment" factor called LEV Listener envelopment ...LEV is the degree to which the reverberant sound, of the first main 2 wavefronts coming from the right and left speakers to the 2 ears directly but also indirectly from early and late reflections encounter themselves for each one of the ears and seems to surround the listener—to come from all directions, thanks to the active controls of the Helmholtz method...


This listener envelopment factor in relation with the source width factor (ASW) put you on the scene of the past recording live event and make you able to live anew the live event like the recording engineer choice of microphones and location choices of these same microphones make it possible, it is a perspective take on the real event created by the engineer...

The original event is not only in your room now, but you are actually there also....All recording are not on the same level of 3 dimensionnality it is the reason i choose this recording for a clear example....

I would like to purchase the world’s first hand made artisanal Listener Envelopment Sphere Helmholtz Mechanical Equalizer from you. I do not want a duplicate, subsequent iteration or refined version of the product, even if it is an improvement - only the original will do. Name your price.

Also, for a separate charge, I would like to purchase a set of in-person multi factor listening room tuning sessions (acoustic, mechanical, electrical and envelopment sphere). My wife has agreed to waive all aesthetic constraints, so you will not be limited whatsoever in our joint pursuit of sonic perfection. Included in the price will be first class airfare to NYC and a 5 star hotel stay. Cost no object - say when.
Thanks for the best funny post answer in my thread to date... 😊😊😊😊😊😊😊😊😊😊

I am allergic to crowd of more than 2 people, and i have never travel in all my life...I navigated the infinite instead, reading...

I dont give a damn about money sorry....I am too old to need money either...



Take 24 pipes and tubes make them a telescopic array in various location of your room, select very thin diameter, 4 times thinner than a regular straw for the necks, experiment with the lenght, have fun and open your ears, and spare your money...

Or buy a 100,000 bucks audio system and convince yourself it is the best in the world even if it is not true...

Mine is the best in the world for his 500 bucks price, if not, one among the better....Anyway i dont give a damn when listening my music... Yesterday Satyagraha of Philip Glass... a big test for any audio system....


Then no need for money to upgrade.... No need to sell you anything....My mechanical equalizer is a free design idea for all....

In my life i was teaching university students in all fields how to read and what to read, and i prefer now to sell creativity and motivation in audio experiment like in my past job, than to sell products or books....

Nevermind the day, the sun is enthusiast even behind clouds and we walk with him under the rain.....

My best to you......

No crowds to worry about - I will send the rest of the family away on a vacation somewhere (including my Vizsla - but he is an adorable little fool who likes music and you may just want him prancing around with us as we optimize my listening space)..

And since money is not of any interest to you, please allow me to instead upgrade your system to a 6 figure one - I shudder like a Sc-Human resonator at the thought of what your passive and active multi factor controls could do when paired with a system of that caliber..
I dont know if you are joking or not anymore...But i know that you like to mock audiophile very much....especially the one who take themselves seriously like me...Then i can smile with you....

But anyway when i listen music in my system, in spite of his limitations, the sound already fill my room and is very good...

I dont want to improve it by working on your system or any other one for a month full time or more sorry...It take times not money to tune a system....

If i could do it, you could; with all the cues i gave in my thread the fun will be yours to make it yourself....

My room is completely "nut" esthetically, and strangers want to put me on an asylum, before listening to my system tough...Not so much after...i remind you that NONE of my devices cost more than peanuts...

😁😁😁😁😁😁😁😊😊😊😊😊😊

Thanks for the offer tough....If i was 20 years old i would have loved to travel free of charge....But like i said i prefer now walking my dog....

Add me to your list of "nut" audiophile in the mean time, i dont give a damn...


Thanks for the laughs....But for now it is enough, i will go back to music...
