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...

After my last experiment with springs, i realize that i made a wrong statement in this thread about the relative importance of the three embeddings ...

NO EMBEDDING is less impactful than any other one....
The contrary impression comes to the mind because when we haven’t reach yet an optimal controls of one or the 2 others embeddings...

Contrary to what i said in the past here, mechanical, electrical, and acoustical embeddings, all three contribute equally in a specific irreplaceable manner to the final S.Q.

Then their contribution is 33-1/3 % for each....No embedding is less impactful AT THE END...

The reason is simple, never mind the impactful power of acoustical controls and treatment for example, the contribution of a better mechanical control under the speaker for example add something that NO acoustical embeddings controls can do by itself alone.... This is true for any embeddings....

These remarks are very important....

antigrunge2,
Sounds interesting.
Why don’t you try it and report your results....

A powerful and non technical musical test for your audio system :



Take a copy of Bruckner 9 th symphony, by Celibidache in my case, And listen to it attentively...

Do you perceive the intricate dynamical geometry between smoothness and intensity, punctuated by silence ?....Do you sense easily the difference between, the brass family, the wood instruments family and the strings family, their slow interpenetrating dances and complex successive motives transformations.... Do you SEE it?

If yes, it is because your system allow accurate timbre reproduction and 3-d imaging that help to perceive the dynamical interplays between musical motives in a 3 dimensions space out of the speakers....
If yes, your audio system is then able to give you an audiophile experience indeed....


If not, dont panic and especially DONT upgrade anything tomorrow...


Read my posts about the 3 embeddings dimensions and controls....


Any relatively good system must give to you what i describe while listening Bruckner....

By the way dont said to me that you dont like Bruckner.... Say instead i never perceived this beautiful dynamical geometry and i dont have a clue about what you speak about.... I will say to you that probably you had never perceived these beautiful motives because your system is badly embedded and dont help you at all.... You probably dont need any upgrade, just some minute attentive listening concentration time in setting your embeddings controls for the months to come and trust me it is fun....And rewarding....

And you are lucky because without clues it takes me few years to figure it out....I has  given  to you some creative ideas in this thread about the embeddings then it will takes you months and not years..... Be creative and enjoy without throwing money in illusions....


My best to all....
