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...

If you go to the "explore" section, and clic on the mahgister systems you will see a photo and a description of my latest experiment, the "singing resonators" made with cheap metal buckets, one stone and some copper tape...The acoustical impact for the money invested on it is astounding...But this tweaks does not replace all other methods implicated in a room treatment... It is only a low cost miracles that add to the imaging way much for his cost...Feel free to try it...
I just finished 8 sets of "singing resonators" made with tin metal buckets, and a tourmaline glued at the center+ a 5mm copper tape crossing the aperture of the bucket vertically...

I must say that if I ever had the money I would go for brass...But the results with these cheap buckets is so astounding that I am totally amazed by the sound in my room...That boost the imaging in all 3 dimensions, in all position for my usual listening, be it nearfield,or normal distance...

Most will mocking my " ingenuity" or ignorance, because yes, these resonance would normally they say destruct the integrity of the sound, but no, in actuality, not at all; I keep the natural timbre I had before adding to it an imaging now out of this world, like some company advertise for their costly resonator products that I would not be able to buy ever in my life... Lack of money sometimes engender creativity... For the student, or poor audiophile, all miracles are possible, be wise, read, study, experiment...It is more fun than buying with blind faith...
One of my friend here suggest to me an interesting experiment in tuning the speakers with wood cigar boxes...A low cost tweak indeed...
I already planned to experiment with ebony wood small plank bought from alieexpress at low cost... My best to all...
