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...

I forget to say that as a consequence of these transparency, the musical timbre of voice or instrument seems now more natural than ever....The lack of transparency has veiled the timbre before I try the crystals tops...Crystals in a macro grid or in microscopics states or powder act magically in an audio system....For me they act like some kind of filtering the electro magnetic field... I am not a scientist for sure...It is only my hunch and experience...


I test these crystals tops mainly and mostly for the moment with headphone, because I put them inside and on the headphone cable also...I will report for the speakers tomorrow...
It is already amazing for me that stones of big size and smaller one connected by cable act synergetically on the sound...But now these crystals powder glued on some paper less than an inch, act so powerfully it is doubly amazing for me...

The miracle is that they complete each other, the big stones and the powder....I think that the effect of these 2 , the stones grid and the powder is complementary, the stones grid act also on the transparency and the timbre but more on the dynamics, the imaging, from the bass frequencies to upper and the grid trough the speakers act on the global soundscape of the room also....The powder seems to act from the higher frequencies toward the down frequencies and less so in the bass...The powder act less on the soundscape more on the fractal relief of each sound, the plancton of the sound, giving more realistic figure to the sound...The 2, the powder or the grid act like filtering the noise and giving more accuracy in revealing all the music...
In the speakers this is the same effect ,like with headphone....Transparency,and refinement of timbre, more accurate tonality of the timbre rendrering… Amazing....Naturalness....Easyness of the flowing sound.... Thanks whostolethebatmobile
Question to the group - How can one be sure that micro or macro crystals are acting on magnetism or electromagnetism (RFI/EMI) and not simply vibration? Answer at 11.
Because they act at distance, on the room or not on the gear but near them....They act on the central electrical panel, this panel vibrate yes but my washer machine vibrate very much but does not effect the sound on the same level than the central electrical panel... Then it is not vibrations the main problem, tough vibrations is a great problem "per se" also for sure and crystals can act to remedy this...
