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 call Groucho to my rescue...



"The space of my room is indeed the other side of the moon " - Groucho Marx
Many years ago a very wise man named Bernard Baruch took me aside and put his arm around my shoulder. "Harpo my boy," he said, "I'm going to give you three pieces of advice, three things you should always remember." My heart jumped and I glowed with expectation. I was going to hear the magic password to a rich, full life from the master himself. "Yes sir?" I said. And he told me the three things. I regret that I've forgotten what they were. - Harpo Marx
But I  must gives you that you always makes me smile.... Thanks and enjoy the day....My best.... :)
Update about liliputian Herkimer diamonds :

I added one on all my 8 Schumann generators in the audio room, the more I added the more the sound increase in clarity and softness without any lost on any count... I added now 3 liliputians on the black Hong-kong Ufeel costlier S.G. that sit on top of my computer screen, between the 2 speakers, and wow...

Never the Grumiaux violin in Bach concertos has been so atmospherical and detailed, the imaging more spacious and the orchestra more present... I listen to this cd for 30 years...I think I know it...

If you want to know what is a good sound, it is difficult to convey that in words even with the best metaphor, but if you cannot stop listen after hours and hours, that is the beginning of a good sound... :)

I will repeat myself, how a .175 gram stones can be more powerful than all other stones, enhancing them all ?
It is only a quartz variety that look like quartz, even if it is called Herkimer diamond... Miracles indeed for 2 dollars all in all... :)


It is not first with money that you can afford a good sound it is with attentive ears and experiments....Nothing else... :)

Update about my "singing" resonators and reflectors...

The configuration of my audio room is not a perfect square...Furniture occupy it irregularly, and one of the speaker is enclosed against a wall for half his surface...A very bad position and remember that all my electronical components are on my desk near a computer...The controls of vibrations-resonance was fundamental...The cleaning of the electrical noise also...It is the reason why I discover by myself the 3 embeddings of an audio system is the ONLY key that opens the door of audiophile experience...Not the price paid for electronic components like most believes in... 

How to create an imaging that is good and entertaining and immersive for that room and for 2 dissymmetrically placed speakers, in my 2 possible listening positions, in nearfield and in a regular one ?

How to reinforce the bass response without alterating the other parts of the spectrum ?

By a selective placement, locations, height, orientation, of my 10 sets of 5 "singing resonators and reflectors ( metal bucket+ one stone in the center with a copper tape crossing the aperture of each one). Low cost and flexibility of orientation make be able to project the sound in the way I want...

I use many other acoustical methods: Schumann generators, Helmholtz resonator, varied materials for absorption on the walls and ceiling....All low cost (S.G.) if not homemade...But without the "singing reflectors I would not be able a so flexible orientation of the sound flows in the room...


Is it perfect? No... Is it very good? Yes...


Cost of the 50 metal buckets 100 dollars... Try that with official acoustical materials and calculate the cost... Brass would cost me thousand of dollars and would probably be better tough... :)


My audio room is astonishingly good... My ears never waited for engineers to say so.... :)
