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...

Getting back to audio...(and miracles)
For some reason, I am finding that the crystals and minerals that result in some of the most dramatic sound improvements are ones containing copper.

Chrysocolla - (Cu,Al)2H2Si2O5(OH)4·nH2O (copper phyllosilicate)
Azurite - Cu3(CO3)2(OH)2 (copper carbonate)
Malachite - Cu2CO3(OH)2 (copper carbonate)
Turquoise - CuAl6(PO4)4(OH)8·4H2O (copper hydrated phosphate)

all the above tested, all incredible performers in the order listed (Chrysocolla best).

I must try to get hold of some chalcopyrite CuFeS2. I’ve had promising results with pyrite which I have on hand, but it contains only iron FeS2. I have to stress that these crystals and minerals need to be activated and distributed by other substances (as used in CrystalTops) or methods (as in Mahgister’s powered grid). In my experience, you can’t just plonk a rock on your amp or speakers and expect a miracle (maybe you can hear differences, but they will probably be subtle).

Power to the Pebble! ✊

"From my limited experience with the crystals it appears to me in my system that they work anywhere, whether placed on the amplifier, preamp, CD player, DAC or even on the top of power conditioners - the same way. Best at improving imaging and dynamics...enjoyable when placed in the rear corners, enjoyable anywhere." - V.R. Sola, 2004

"I cannot listen to my system any more without the pebbles." - Hans-Peter, Switzerland, 2004

Hi-Fi News Show, London, Sept 2003 -- Audiopax/Ecosse/Meitner exhibit coordinator (Precious Music, Scotland): "Now, if I say that dozens of people said we had the best sound at show, many other said we had the best sound they had ever heard, many dealers, competitors and reviewers came round to check out the room and in particular the Audiopax Amp and Meitner dac...well you can imagine we felt pretty pleased with our efforts." (4 Brilliant Pebbles were used in this room -- one on each Audiopax speaker and two in room corners.)

"After some experimentation...I tried them in the rear corners of my room behind the speakers and liked them very, very much. They appear to affect the entire presentation in these locations -- providing more clarity, detail and, for lack of a better term, "naturalness" that is quite appealing. Soundstaging and "image density" is improved; treble is more extended and the bass has more snap and fullness to it. Micro- and macro-dynamics are enhanced. I already had the corners treated with Roomtune strips and corner tunes and use Argent Room lenses in the system. How do the pebbles work??? -- I'm intrigued, to say the least. I've been "Machina Dynamica-ized" for the second time." -- Jim O'Neill, O'Neill Medical, 2003

Oops I forgot about your Brilliant Pebbles. Well, I did say you probably would hear the difference.

Radio frequencies are like Chicken Man. He’s everywhere! He’s everywhere! RF is coming in through the windows, coming in through the walls, rf is entering the unused wall outlets throughout the house or apartment. Radio frequencies (electromagnetic waves) are produced by electronic components, especially microprocessors. Since radio frequencies are photons and travel at light-speed, directing them away from one object simply allows them to go and affect something else, no? Does carbon absorb photons in the rf spectrum? Carbon seems to be rather good at absorbing visible light.

A comprehensive program of radio frequency shielding, absorption and suppression is required to effectively deal with the pernicious and tenacious problem of rf interference. A couple of suggestions are Machina Dynamica Flying Saucers 🛸 for Windows and Flying Saucers 🛸 for unused wall outlets everywhere in the house or apartment. There is a 3M rf absorbing product that can be easily cut into rectangles or squares and stuck onto the tops of microprocessors but the name of the product escapes me.

For emi coming into cables or any equipment from anywhere/everywhere, there would seem to be 2 ways of dealing with it. Absorb or reflect. If it is absorbed, surely it must be dealt with (preferably converted to heat) before it is allowed to interfere with the audio signal. If it is reflected it might arrive somewhere else undesirable. Unless all equipment and cables were treated to reflect. There must be some good reason why the Belts preferred white cables. Perhaps a substance with an extremely high refractive index might be useful.
