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 just reinstalled one Mat and 4 Cards in the system after giving them two days in the breaker box to “charge” them up, as it were, as suggested in the threads on such products. The charged up Mat went under the Sony Walkman CD player, which is on a special spring based iso stand, Fr circa 2 Hz. 

Two Cards went on my Sony DMR-700v headphones and the other two Cards went on my two BLACK USB Schumann devices. I also attached a Golden shungite plate to each BLACK USB device for good measure. The BLACK USB devices are isolated mechanically via suspension and are located at height of 60 inches. Better safe than sorry. 

I should mention I also recently treated all contacts of the BLACK USB device including wall outlet with Total Contact, the Graphene contact enhancer, so those contacts are still breaking in. Nevertheless all these recent changes have wrought a big boost in dimensionality, dynamics, resolution and naturalness. I shan’t attempt to ascribe effect to causes however, although the charging of the Mat was an obvious big effect.
Add some Herkimer diamond to the golden plate Geoffkait and compare that with other tweaks....You perhaps will be surprized?
Thanks for reminding me, I also have Mikro Brilliant Pebbles packs of crystals (includes diamond) on both wall plugs for the BLACK USB devices. 🤗
Ok.... Perhaps if you add one tweak at a times you will give to yourself and others some assessment about each one effects....

I say that because if I read what all others has said about their mat effects , I have the same impressions with the "golden" plate effect on the breaker box, behind speakers.... etc... I use around 20 of them.... :)


Thanks anyway for your report.... My best to you...
I just bid on some Herkimer diamonds from China. Better safe than sorry.
