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...

Not at all my friend, but my wife watch me and will kill me if I spend money for audio....

I must act with imagination and small money.... But I thank her my audio is over the top for his price...

I offer to you my mate and eternal thanks....
Imagination and small money are the essence of innovation...
A nice mate sounds good today!
Update about Alaskan 3/8 inches cones:
 golden one are nickel, black one are copper....


I just add 2 on each exterior side of the speakers where there is already 2 on each front side of the speakers...

I now have added 34 cones in the room... some with Herkimer Diamond inside for adjusting bass response...

It seems that all is going for increased improvement....

more to comes I had 11 others cones to place....

:)


Update:

I now have successfully place 39 copper Alaskan cones 3/8 inch...

The sound in near listening at 3 feet of my speakers is more 3-d layered than ever...

At regular listening position on my seat at almost 8 feet from the speakers that are on my desk with 5 feet between the center of each other, the room is totally full of the sound with no more relation to the speakers at all, even if the position of the speakers is not symmetrical in relation with the wall...
One of my speakers has two of his side inserted a few inches against the wall...I succeed annihilating mainly the distortion of the soundstage....

For 30 bucks these 45 brass Alaskan cones were one of my most precious and powerful tools to modify the acoustical field of my room...I stole the idea from a tweaks company that sell something resembling that 7 for 400 bucks ( I forgot the company name)...Imagine if I had bought them instead of replicating them.... I dont think that acoustic sound waves act better because they are more costly.... :) Some customers of this comnpany even says beware to not use too much of them because of sound degradation.... It seems my cheap cones ignore sound degradation they are more light and I can increase the S.Q. by balancing them with some Herkimer nano diamonds...Inside each  there is a hole that I fill with copper tape....

:)


Tomorrow or in a few days I will put the 4 last one behind me...And two others will be added to the 2 already glued on my computer screens between the speakers....

To be continued...………...


For all those who read this thread my hope are the best for all.... music is a great help in confinement....Stay well and be cautious in these perilous times....
