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...

The Fostex T10 the first portable orthodynamic, and for many orthos cultist one of the best vintage ortho was for me right out of the box better than my Hifiman He 400, another ortho, for naturalness of timbre and way much better, because the He 400 has ever sounded artificial...

But compare to my cheap Fostex TH 7-b modified and damped there is no match for me...The lesson learned by me is price does not means nothing in headphone, and modifications is mandatory...I will modify the Fostex T10 in the next weeks to come...This is a good planar headphone...

One of my goal in my audio search for heaven is to use a lithium battery generator to freeing myself of the electrical grid of my house...Tweaking the electrical grid of my house and audio room teach me how the high level noise caused by EMI and RFI interference plays the greatest role in destroying the potential of Hi-fidelity of any audio system...I tweaked all my house electrical grid with stones with a big audible effect, to the point that this is the biggest upgrading effect known to me for my audio system...


Using a generator must be better, especially if I tweak the battery generator with the stones and crystals also....

Perhaps somebody here has already a big lithium battery generator ?

I am curious to listen to his impression and advices...For example the Yeti of Goalzero or this one:
https://www.kickstarter.com/projects/ecoflow/delta-the-new-standard-of-battery-powered-generator

The only problem I guess there is with this solution is the fans noise of the battery.....

Around one thousand bucks this generator will be costly for me but, I have no other real upgrading solution with my actual system...And in 2 years maximum I will be in the obligation to sell my house and go to rent location of an apartment, then I will not be able to tweak the central electrical panel of the house apartment...

As everybody and his brother knows I am using lithium battery powered SONY Walkman 🚶🏻‍♂️CD player with SONY MDR-v700 headphones as my primary system. In case I haven’t mentioned it more than 20 times already, allow your friend and humble scribe to fill you in on all the gory details why lithium battery powered portable CD player + headphones is the only way to fly.

Aside from the obvious advantage of completely eliminating issues with house AC power, my system also eliminates issues with AC GROUND, power cords, interconnects, digital cables, big transformers, fuses, big capacitors, big long speaker cables - and the oft astronomical costs of them. Plus, it’s easier to isolate the lightweight player. And you have enough money now to go hog wild on tweaks. If dynamics, low noise and distortion, tonality, realism and air are you’re bag, this system has it all.
