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...

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...
