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 about all these devices and improvement...


I discovered all of them with great listenings feed back sessions and luck...

I dont know which one is better in an absolute measurable sense of the word, save for my listenings impression...

Then i dont know which will be the better for you to begin with in your own noisy House/room/system...

But anyone who will judge hastily them without really trying some in some way will make an error....

My last device is a luck incident, i bought this ionizer for killing the viruses not for audio, but i remembered myself some fact about ionization and audio then it was it , the improvement is amazing....

Like i said in a normal, non rightly embedded, more noisier system than the actual mine, i dont know which % of the positive effect will be audible by you.... Then eliminate the vibrations of your speakers and gear first, put the "golden plate" all along the electrical grid at stategic location.... Treat acoustically your room, try some modified cheap Schumann Generators.... After that try the ionizer....

Short update:

My ionizer is really amazing....







It is not so much the Electronical design of this or that " Branded name" product which will give you an audiophile experience; at first and at last it will be the breathing synchonized waves in the acoustical space of your room.... Nothing else, nor a new cable, a new dac or a new amplifier, and most of the times even not a new pair of speakers will do it satisfyingly....

This "breathing sychonized waves" is an event coming from what i called, passive materials treatment of the room +active Controls of the acoustical embeddings...

Add the other 2, the mechanical embeddings and the electrical grid embeddings of the audio system and of the house and NO upgrade of one of your electronic component can rival and beat the rightful embeddings controls of these 3 dimensions... NONE....

This is the only one truth i experienced and experimented with....

I will let their upgrading process to sellers and buyers...

Second short UPDATE about the ionizer...

Not only timbre decay is better but really the imaging. where each instrument if connected together reveal an acoustical atmosphere of their own, each one in his own aural glowing presence, the imaging flow in my room way more detailed and cohesive... Spectacular more refine in nearfield and on his own more dynamical  way in regular position... I cannot chose between the 2 postions like always, nevermind the files....

This is really more than icing on my acoustical embeddings controls cake...

This is impossible for me now to take off the ionizer....

My best to all....
Hats off to you, Mahgister.  I received the "family" version
of moskitofree from France.  I agree with your comments.

The device probably should not be used when music
is just meant to be a backdrop for other activites.

When the device is "on" it simply brings the music
closer to you, and you become more aware of everything
you like, about what you are hearing.

I have used the device to treat cds, wanding for five rotations,
before playing.  And doing the same around each ear.

The ionizer is silent and does not really move much air.
It is making a huge impact in what I am hearing, and is a
most pleasant surprise!  A keeper, for sure.
Thanks sgordon...

It give me pleasure to have some positive review about my thread or about my ideas...


I wish you the best....
