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...

Generally useful geoffkait send Greetings🖖 from future. Maybe not your future, but future, nevertheless. Future have no audio forum so I come back here, mostly for jokes. It’s funny. When I was little boy and told people I was gonna be a comedian, everyone laughed at me. Well, no one’s laughing now!

Oh, I’ve been meaning to ask, how’s your experiments with mind-matter interaction coming along? You know, the .... message labels.

I will go with it soon but now is not the time  for me... 

Do you imagine what people here will say if I report here with these "crazy experiments" ? That will kill this  dying thread, and the goal of this thread is to be hijack by more knowledgeable people than me for the benefit of all (me included)… There is no pleasure for myself ranting alone here.... After all there is not many threads here with this set of goals isn't it?

Mahgister ...

The lengths we go to in order to improve our sound systems seem rather silly to many. But ... proper tweaking can really make the difference between a so-so system and one that approaches world-class.

You mentioned using copper foil. I have small copper foil strips around the edges of my large living room (the listening room) windows. Same thing with the artwork on the walls. They are covered with glass and are a reflective surface. Same with the glass fronts on the built-in cabinets in the adjoining dining room. Tim Mrock, the owner of Perfect Path Technologies turned me on to that tweak about two years ago, and it did help with the SQ.
