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 it won't mar the finish on your speakers, try the copper foil tape on the inside sides of the speakers in various locations. There's another possible improvement to be had there.

It continues to amaze me how many folks will just laugh, scoff and dismiss these ideas without trying them for themselves. I mentioned the glass cabinet doors on the dining room cabinets. There's four of them. I found that just by leaving one of them halfway open, I get an improvement. It acts like another room treatment. My friend Robert discovered that when I inadvertently left it open during a listening session one night and he was sitting in the sweet spot.

For sure the copper foil tape is an idea I takes from your site GeoffKait...I already thank you for that... I imitate the Master for sure...

Do you means opening the speakers box and placing the copper band inside? or can I put it at the exterior side?


Putting the copper band yesterday on the glass or metal surface in my room, and not only on windows or on the wall sockets like you said gives me a better separation but mostly a better dynamic very audible principally in the normal distance of speakers listening....

The products are my intellectual property. When am I going to get royalties? In your country it’s OK to steal ideas? I don’t care if you are on welfare and living in a tree.

Somewhere Geoffkait on this forum I read your advice to somebody, I dont remember the tread, about copper tape, free of charge... You cannot ask royalties for copper tape....And I read also others that know about this tweak...Like Oregonpapa…

1,
you add some "magic" to your copper band, and your band is different from the tape I bought...Your intellectual property are the "designed "flying saucer" with their particular geometrical form...
Or 2,
the tape I bought and your copper band are the same, except for the geometrical shape...

I dont know what is true...


But nevermind which is the truth 1 or 2, you cannot ask me money for the copper tape I bought...After reading your site and some other people that added that to their tweaks, I have decided to experiment with that...And my thread is about "tweaks" nevermind the mouth where they come from...And by the way I mention you few times and thank you about that for others to know...
