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...

Human owns their habits like a shirt, they know that it is an habit but they are proud of it or try to makes that habits an object to be proud of and not only a relative action...

I had discussed with some about their audio system and reviews and reviewers, and they cannot see that their tastes are habits solely acquired through certain limiting circumstances and that owning a relatively good audio system is not related directly and mostly to these relative tastes... Then reading reviews of electronic components of someone with the same taste habits is only slightly more useful than reading the financial markets, if our goal is to create a real relatively good audio experience for ourselves...

This creation is directly relative to our own conscious works and experimental plays with the 3 conditions linked to the embeddings of the audio system in a mechanical system (vibrations-resonances controls) in the acoustical field of a room and in the electrical grid of the room and of the house...(There is also others confitions than these 3, but we must begins somewhere with the most basic one)

Where is tastes in that context? How tastes can play any other role than a secondary one?
We all had the same taste and dream about a real Hi-Fi experience and the objective conditions to realize it...Tastes comes on after all that and is more an anecdotal preference, linked to the place we comes from, than a real factor for an objective experimental creation...

Reviews and reviewers are entertaining. sometimes informative, but they act like many pro and not pro-reviewers did, relativizing finally all to "tastes"...They dont speak, forgetting any specific electronic component whatsoever, about how to make them all great, whatever the components... Who will sell anything if the set of all very good  electronic audio components is too large?


I wanted that to be said somewhere without hurting feelings... :)




"Before choosing my wife sure I taste it " -Groucho Marx


It’s human nature to become more and more attached to one’s own ingenuity and to embrace his results and conclusions with great fervor. But, I caution you, gentle readers, one must be open minded at all times and ready to change directions at the drop of a hat 🎩 It can be quite difficult to break out of the lower energy orbit into a higher energy orbit. As John Lennon advised, there is nothing to get hung about. Sometimes we benefit from taking a break from our daily routines. As Groucho Marx advised to his guest with ten children, I like my cigar but I take it out sometimes. 
A note about Herkimer diamonds...

I use H.D. normally of 1 or 2 grams...

I try some very little one on top of tourmaline stones that are themselves on my S.G. They weigh only a fraction of a gram...

Incredibly for me they seems to work with the same impact that the bigger one...they are like thin sticks, like an antenna, that enhance the tourmaline stone linked to the S.G. the effect is mostly a more beautiful distinct imaging...


These S.G. modified transform the acoustical space in a way that no materials for room treatment, nor any resonator, Helmholtz one or others can equal...


I dont need an explanation to hear it tough.... :)

The cost for this experiment was a 2 dollars amount for 16 little H.D. 3.5 grams in total...

I test that with the 100 transcendental studies for piano by K. Sorabji, a genius for the future...


Update for the liliputian H.D.

The effect is confirmed for me and surprisingly subtle but evident, a more softness in the imaging, without any loss, in any aspects of the sound...The effect remind me of a change of cable ...Like with my Morrow M3 compared to ordinary interconnect...It is in the same order...

I am flabbergasted that adding a .200 gram thin Herkimer diamond produce a change....on top of a chunk of tourmaline... On 6 of my 8 Shumann generators...The liliputian H.D. seems powerful on another level compared to the 2 or 3 gram H.D. they seems to add a softness that was not there even with the big H.D.


For using behind speakers for example, a golden plate + a big H.D. will be better... We need a powerful action there to balance the shungite…


For using with the S.G. we need a more subtle action no less powerful but more toward softness than cleanliness...Then the liliputian H.D. are the best...


Audio is not what we think it is at all, engineers, audiophiles or whoever we are; audio is a complex activity combining many artefacts in an experience always new, implicating more than one science, and some unknowns to discover and perhaps even more than we think at the end....

I cannot stop listen what I listen to, now Vivaldi, with a softness that is miraculous with the Biondi violins...

All that for 2 dollars for my 16 liliputian marvels....... :)
