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...

Good night, my friend. May the beautiful sound of your stereo curry you off to sleep....:)
Thou shall not curry favor with obsequious English majors. - old audiophile axiom
Crystals powder is miraculous tweaks like my stones grid but more easy to makes...The effect are more evident with my speakers today... Break in? I dont know...But none of my favorite music has ever sounded so natural...The velvet smooth sounding coupled with a better imaging linked to an enhancement of micro details, push the results that I had gained with my stones grid to another level...The effect trough the speakers listenings is linked to a small band between the computer and the optical convertor, and 2 bands perpendicularly place against the 2 cables coming from the dac to the amplifier... Also 4 squares(1/2 inches square each) place freely on the capacitors of my 4 shumann generator that act with these bands like with my stones some kind of enhancer of the crystals effects … This is so little crystals for a so great improvement... Baffling experience for me...My stones grid was more difficult to make and has a similar very great effect but with less subtle refinement, it was lacking the polishing of the sound effect that the powder gives to me...


Anybody that doubt the crystals effect in audio must reconsiderate and begins experimenting...No upgrading of a piece of gear at a reasonable cost can gives that...Sonic heaven at low cost is possible...

I’m giving serious consideration to promoting you to my chief Brilliant Pebbles salesman. It’s a good thing I took atomic physics in school. But seriously, your enthusiasm is contagious. A-choo! Next up, shall we consider introducing the concept of sound hierarchy, which states that if a reasonably good system can be much improved by tweaking what does that imply for really good systems? I mean no offense to anyone with the term, inexpensive system as I have one of the absolute least expensive systems extant. Total system cost around $20. But that does not include tweaks, which I venture to say is well into the many thousands.

thecarpathian and mahgister,

Thanks for your care about me. It is touching and I mean it. You made my day.

I am well but, after realizing that many threads I have participated at have been shut down, I also realized that my contributions were neither welcome nor necessary. Not that threads were shut down because of me only, but it became even more pointless participating.

At the same time, I have to admit that geoffkait was correct about my whereabouts. I was away. On the day (August 12) thecarpathian asked where I was, I was probably bicycling between the fields, up the hills, or around the lake after Fête des Vignerons had ended. A day or two later I dedicated my evenings to the Imperial torte and a few more childhood memories.

Having said all of these, again unneccessary, facts, I think I am quite close to geoffkait now and will go for a bicycle ride around. Good news may be, I do not know how he looks like so we may not recognize each other.

Again, thanks for your concerns about me. I appreciate them.
