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...

Adding new stones


Over the Sansui AU 7700 Amplifier transformer I already have many stones: tourmaline pieces, amethysts, agate... I put a very little "golden plate" (because a bigger one can kill the sound then beware) and with it I added 150 micro Herkimer diamonds.... That gives me more depth in the imaging and a better natural timbre.... :)

Herkimer diamonds and shungite in the "golden plate" are the most useful stones for audio, over tourmaline, agate, quartz, and all others I used too...
Where Kambaba jasper can makes things sometimes better....


I put a 200 gram sphere on top of my Sansui with the 150 micro H.D. and the very small "golden plate"... Before I tried an agate that gives me more meat in the sound, but I want more details then I replace agate with a Black tourmaline big chunk with success...After a while I tried my Jasper Kambaba sphere and Bang! the imaging and bass frequencies were better with keeping details and air around the sound given to me by the H.D....


This an example of experimental listening ending in a success.... :)


Cost: peanuts....
Goal: tweaking the sound toward the superior potential level......
Results: more beautiful music with great fun experimenting with the master’s ears.... :)

Nota Bene:

Kambaba jasper is known by me for the last 5 years, this stone improve the frequencies perception like tourmaline for example but with a potent working on the imaging perception more than on the timbre perception only, like tourmaline....


Some people reading my many posts here can think that I go forward and backward alternatively with the sound quality without knowing too much what I do...This will be wrong, I know what I do after all those years of experiments and past some experiments where some trade-off are mandatory, the general trend is a cumulative positive progression in S.Q. for at least the last 2 years in a very audible way, each stones complementing some other one....I know the working of 20 stones at least and play with them very well in various way toward the optimal way....


Then this last experiment help me to finetune my amplifier, already tweaked with stones.....This was a success....These methods are so efficient and subtle then I learn and discover each week.....Finetuning is a process not a single experiment....
Most of the times people dont go in a finetuning process, and dont know how in the first place...

They upgrade after a long or short time moving the problem around half the time.... Upgrading is sometimes for the better for sure but when someone dont know how to optimize the S.Q. by his own means, often they forget about the sound and lives with the music and it is ok for sure....

But it is way more fun to improve, month after months, and at the end music comes from our own hands more than from a purchase that is often as illusory than it was good at first listen....So good they are any electronic component need to be rightfully embedded and no designer will like to say frankly to his customer : " you know my product is perfect but to listen to his optimal quality you must learn now how to embed it in your house"....Who would buy it thousand dollars, only to know that right out of the box the product is not at his better level of working order ? :)


The other reason is after all the electronic designer of an amplifier or a dac or of the speakers are not acoustician, physicist or electrician, and dont live in your particular house and room....They are interested in designing not in the embedding so much....Design is an idealized standardization process, acoustic of someone room is more an individualized subtle embedding process, not reducible to standardization....

After the acoustic the same is true for the particular electrical grid of your house and for the general mechanical resonance controls problem...Any electronic component vibrate and affect the other E.C. and all the audio system is affected by the vibrations in his neighborhood... These are the 3 embeddings problems to solve.....The more important fact in audio.... It is simple but nobody on any forums explained it clearly to me and I read thousand of hours to understand.....I want to be clear myself and dissipate the upgrading myths.....


For sure many reviewers speak about some products dedicated to one of these 3 embeddings times to times...They called that a tweak....But this is a long way to understand the 3 embeddings problems, in fact no one can solve that problem with a tweak or even with a few tweaks....We must be systematic....No reviewers would be invited to speak about something at all if they dared to say the truth: the embeddings of your audio system are way more impactful in your experience of Hi-Fi than the upgrading purchase of only one electronic component in general most of the times (speakers, amp or dac).... This is the upgrading myth.... :)


UPDATE Kambaba jasper

Wow!

I am lucky to had bought 4 spheres at a times where they were much cheaper.... Their effect is stronger in my controlled embedded audio system especially on top of my Sansui amplifier....This kind of jasper increase the imaging from my first use of them but now more audibly, i dont know why at all.... :)


i will give to you an example of use, the golden plate will give more meat to the sound but will slightly compress it, add kambaba jasper and you will keep the meat but you will erase the compression and reinforce the imaging....It is an example of complementary use of stones.... At the end with many kind of stones you keep only the positive.... This is really like an upgrade.... And better because of the low cost and sometimes it is more powerful than an upgrade because you can work all aspect of sound.......

I will never use a tube amplifier anymore.... when i hhave one i try plenty of tubes, with subtle changing colors in sound each time but that was very small and limited effects compared to my stones tweaking without speaking even of the controls of the 3 embeddings....

Except i dreamed to buy the tube ZOTL Berning amplifier but it is another story.....
Although not a tweak per se, the ADD-Powr approach to extracting improvements to audio is nothing short of a "miracle."
Power system "tuning", "harmonizing" are areas that have been largely ignored.
May I suggest, that all of the products are worthy of serious consideration to audition. With a 30 day money back guarantee, you have nothing to lose.
The ElectraClear or Symphony are good products for first timers.
