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...

Have you compare these crystals natural versus artificial? In what sense are they more powerful? And where do you place them, how do you use them?

Thanks very much for your time and interest...
I use them crushed, painted onto paper with various other ingredients, and wrapped around RCA or XLR connectors or cut into small pieces (15mm square) placed in strategic positions. I can send you (or anyone else) some examples to try, my pleasure. I’m not selling them, they are just gifts for friends and interested individuals such as yourself. I call them CrystalTops. You can also cut a 3mm square or a 3x5mm rectangle, superglue it to a standard fuse and save yourself some money.
The most effective artificial crystals are these one on the list you give on your post : azurite, malachite, turquoise, mica and ruby.

Or there is also other one you have tried?


I never tried artificial stones, and would never even had the idea except for your suggestion...


One thing that surprize me was the cost of the synthetic stones,higher than the natural one same quantity, for example tourmaline in this list:

I am very curious to compare the difference between natural and synthetic, the problem is the cost; and how can the synthetic be better or even equal to the natural? And be it on the same level as the natural kind, if the synthetic are costlier than it is less interesting, except if they are better of course? Perhaps the crystalline purest structure without impurities is the key? What do you think?
I never met a crystal I didn’t like. But crystals don’t act like people think they do. That can be a problem. Consequently, people tend to get carried away before it’s too late. It’s a common audiophile phenomenon; they get all revved up. There is a name for it in psychology. Self-fulfilling prophecy, or something like that.
