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...

Because they act at distance, on the room or not on the gear but near them....They act on the central electrical panel, this panel vibrate yes but my washer machine vibrate very much but does not effect the sound on the same level than the central electrical panel... Then it is not vibrations the main problem, tough vibrations is a great problem "per se" also for sure and crystals can act to remedy this...
I thought you said you put crysutals inside and around the headphones and cables. Perhaps I misunderstood. 😬

Of course the washing machine doesn’t affect the sound as much as the electrical panel. Even if you’re washing clothes while your system is playing. 
I wrapped only one piece, on the headphone cable, the other pieces were inserted freely between the cup and the earpads...The other were freely place on the capacitors of the S.G. and a last one between the cable of the optical convertor and the computer without wrapping only placed without pression ….Even the only one piece wrapped were not wrapped tightly because the material is rigid and bend but not easily and not tightly, it is like an envelope around the cable attached with tape around the connection  in the middle of a 10 feet cable ...
So, it was touching, right? I never said it had to be wrapped tightly. 😬 We know vibration is an issue with cables. That why we elevate or suspend cables and power cords.
yes I see what you means....But I dont deny that vibrations absorption plays some role....I doubt that this was the end of the story....The effect is so special...But I will listen to you, I dont know really   :)
