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...

UPDATE: Your speakers dont like to live with 4 empty ceiling corners....



My thread was sleeping for the last month, but my imagination was not completelt in sleep mode....

I add some rectangular and triangle piece of cardboard covered with aluminium paper to 2 corners of my ceiling room in diagonal opposition, one of my speakers near one of this corner....


Cost: one peanuts or 2...

Acoustic material treatment improvement: very audible increase if the refinement of the higher frequencies in particular...the imaging is increasingly stellar one change after the other.... This addition is no exception....

If your room is too bright adding thick pieces of old rug to the cardbord will do better....


Trust me speakers hate the 4 empty corners of any room....Treating 2 for me was enough to be in heaven one times more....

Am i the only one who play with the waves and do miracles for peanuts?

Merry Christmas to all souls....

I have been using silver 3M tape, 2" wide.
I bought a roll to join some ductwork, to vent a clothes dryer.

I find it is probably thinner and lighter than the copper
tape I was using in audio applications.  I like the way it
"smoothes" sound when applied to different surfaces...

UPDATE: Your speakers dont like to live with 4 empty ceiling corners....



I just add a third corner treatment....With a rectanchle of hard cardboard and one triangle shaped cover with aluminium paper....

It is astounding...

My test cd is some violin concertos of Vivaldi played by the miraculous Belgian violonist Arthur Grumiaux...

His main tone deliver a living light waves that fill the eyes by passing trough the ears, not only in this Vivaldi but in Mozart Quintet or Bach violin concertos cd....

My treatment of 3 corners makes it more audible than ever.... I am in love for the last 45 years with Grumiaux.... Some are greatest virtuoso, like Heifetz, none exsude color shades and hues of sunlike heat like him....

I am very sad that the King of Belgium dont mandated him by special order or law to record all Vivaldi....

It is a pity.....

Dear friend remember this: Any speakers better he is and stronger it become, the room is always stronger....

The speakers are like a sleeping princess kissed one day by his powerful knight: the room after be treated acoustically...

If you room has no acoustical treament and embedding controls, you will never know what your speakers are really able to deliver....You speakers will stay quiet like a young girl eternally sad and which has never fall in love.....

My best to all ghosts and living souls.....

ANOTHER UPDATE: Your speakers dont like to live with 4 empty ceiling corners....

On the five corners in my room now the fourth have been treated by rectangular aluminium covered cardboard plate and a triangular one, forming on the corner a kind of half pyramid......


I was not dreaming one month ago about another increase in quality so much audible.... I was really thinking that my embedding journey was over now....I was just listening music not the sound.... 
😉
What a mistake....

I read 30 years ago about the particular effect of shape on the quality of the energy field.... Corner was not the best place for positive energy.... The great Austrian architect Rudolf Steiner was also replacing often corners in his design by regular or irregular undulating  polyedral shape...

3 days ago listening music all that comes to my mind....

A bit of cardboard and aluminium paper, a bit of transparent tape.... All was done....

Another fantastic acoustical embedding passive control free of charge for those of us who dont walk together dancing to the same tune with most....🐑🐏🐑🐏🐑🐑🐏🐕‍🦺

Merry Christmas....🎄🎀🎈🎁😌

I return to violin music, it is better than ever here......
