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...

My new tuning room device:

" Helmholtz-Fibonacci silent organ". 😎




I use a brick with holes in them for supporting copper/zinc standard plumbers pipes...

The diameter of the pipe are: 1 centimer and 1/2

The 3 pipes have respectively 2 feet , 3 feet and 5 feet lenght....It is the Fibonacci  golden mean ratio between the 3...

The effect was amazing and very noticeable on all counts...

A more optimal results could be obtained but i dont have the different diameter to try against different lenght...

These are standard plumber pipes...

Anyway the result is more than good....

In the last 2 weeks i improved a situation that i think was already good...

We have been brainwashed by reviewers of electronic component in Audio... 😁

The embeddings controls is the road..... Upgrades are at "some" point very silly or not so useful  act.....

Keep your  good audio system and try to embed it rightfully first .....


My best to all....
UPDATE: " Helmholtz-Fibonacci silent organ". 😎 My new room tuner set...




I am very excited....

I just finish to install my second set...

Just a new brick with holes where i posit 3 other copper plumber pipes with same diameter than the other 3 series BUT,

With new ratio lenght/diameter: respectively 12 inches, first pipe, and 20 inches, and 32 inches.... A golden ratio also but with another set of frequencies cleaning scope....

Results:

With the 2 sets not straight in front of my speakers, but laterally located, Amazing ....Better focussing of all frequencies range then all tone cleaner....Better timbre and better imaging in my 2 positions of listening....

Thanks to our fellow audiogoner audiotweak that suggest me the Argent " room lens" 3 set of 3 big tubes 6 or 7 feet high, open, with all the same lenght....... I tried first bigger plumber tubes ressembling this produc but with unequal lenght, one 8 feet, the others 5 feet, 2 feet...But my results were better closing the superior aperture and inserting a straw, more like in a real Helmholtz bottles...The results here also were very good... But not having a 3 feet tube was probably handicaping my results.... I cannot use the Fibonacci numbers ratio here...

Anyway i could with the thinner 2 set of three pipes.... 😁

Life is good....




What is more rewarding: buying a new amplifier, the Berning ZOTL of my dream or creating my own new device, the Helmholtz-Fibonacci silent organ, my own room tuner.... Guess which?

i can affirm to you that the upgrading effect is very strong and i dont recognize my favorite files for another the Nth times in the last 2 years...

Dont throw money, think, try, listen and enjoy....

Dont listen to people with highly costly system, they will never believe you that some plumber pipes can give what some many thousand electronic new upgrade can usually give....

I dont believe it myself...

I juste listen my music smiling and very proud.....

😊


I sell nothing except creativity....Have faith in yourself....

God give us ears, they are the best computer, not for analysing frequencies, equalizer are best for that, but to perceive music they are not replaceable for the time being....

My best to all....

I forgot to say in my excitement that my pipes are what i take from my basement in the state where they are...

For an optimal working i would be in the obligation to cut them to a very precise ratio of lenght as that in the fibonacci ratio....Which they are not now....

But i give you the idea...

It work amazingly good as it is with in eac case the longer being the sum of the other 2, i dont doubt that with the right ratio between all of them, they will do a greater  miracle in tuning the room...

I will add a third set of 2....My last three pipes with the same relation between them.....


to be continued soon..... 😊
UPDATE: " Helmholtz-Fibonacci silent organ". 😎 My new room tuner set.. H.F.S.O.


A more precise ratio between pipes is of fundamental importance... A+B/A=A/B=1.618

2 inches less or 2 inches more on only one pipe alter the sound very greatly a very clear focus but with not enough meat on the tone bone so to speak with the 5 inches pipe, then i switch to the 7 unches with great improvement.... This third set is less well adjust toward the golden ratio tough....It work very well tough, i will adjust that in the weeks to come....



I add a third brick with a set of 23 inches and 14 inches and 7 inches....Not enough near the golden ratio but anyway, way more better than the previous 5 inches... The difference between 7 and 5 inches in this set was astounding.... 😊

The other 2 sets has their 3 lenght more near the golden ratio, this one not enough.... But anyway this third set work another level of refinement all across frequencies....

I locate it behind my head in my regular listening position....

This H.F.S.O. is my best best discovery with the "golden plates" and the modified Schuman Generators grid.....

Oufff what a day in music and audio.....

My best to all..... 👀
UPDATE: H.F.S.O.

I almost woke up  my wife going in the basement in a hurry...

I sawed one of  the pipe of the third set to improve the set  by being near of the area of the golden ratio...

A good thing, listening the same files in a few second all was better, at the same times the sound was  more focussed in all frequencies but without loss this time in the "meat" around the " bone" of  each tone ....

Greater pipe: 23 inches 1/2, the second one near 14 inches, the last pipe around nine inches.... BINGO!.....

Third set completed and i go back to the music....

More to come....
