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...

If you think the powered grid of stones is close to the freakiness of the photos in the freezer tweak you must be thinking of a different photos in the freezer tweak than I am. It’s a freak out! 😲 But I can certainly understand your reticence in talking about such things. Boo! 🤗

I’d be very careful if I were you. Have you given any thought to what your family would say? Hey, Dad, what’s the deal with your photos in here? And what’s with all the writing on the photos? x’26’x ? ‘x = PRESENT TIME ? SAFE HOLE = O. K. What the hell is this?? Dad!! 😬

Of what people think of me about my craziness, I dont give a dam, especially in my family...

Of what people think of me about my moral standing it is another story and it is way more important to me... :)

This is your evening lesson, son!

I put a golden plate, not on the central electrical panel of my house in the basement, I had already 5 G.P. there, no, this time, I put it on an electrical breaker panel in the second floor of my house near my audio room... I had only lava beads on this panel already, adding the golden plate makes a big difference...


I accidentally forget today to connect 2 USB Schumann Generator, and the sound was slightly more compressed, I connect them anew and bingo! the imaging was there like never...


This 10 dollars S.G. works marvellously and at around 80 bucks for all the 7 ( I dont count the BLACK UFEEL one at  50 bucks) I dont know if the top Hi-Fi audiophile Acoustic Revive one will be able to replace them all... I dont think so for the simple reason that their range of action all around me at different height variation is better than only one, even more precise and powerful... The Black UFEEL is precise tough and in the critical spot seating on my screen computer  that makes a big difference...The Acoustic revive S.G. is way too big to be located there...
But the difference in cost is so much I dont ever think about that one...And they work audibly well indeed located around my listening position in my small audio room...Then for me it is the deal...Cheap to replace also... 

And believe it or not I use one of them near my bed and my sleep has never been better for the last 3 months...
