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...

Try with my thin "golden plate" = one little shungite plate for cell phone+ copper tape on one side...

There is photo on my "virtual system" page...

Place it on the usb platform of the S.G....You can add some tourmaline or Herkimer diamond on top of the golden plate to modify the sound to your liking...

I have both Synergistic Research hfts and DIY hfts
describe these DIY HFTS ?


Thanks for the report...
By the way the Schumann generator for sure affect the acoustical perception of the room, but I use it with the golden plate and some other stones to enhance the effect...And it is way more powerful with that then only the S.G. without anything else on it...

The S.G. work like a stone " filtering" power enhancement system for the acoustical grid of the room... But Stones and golden plate also "filters" in a way the electrical grid this is my experience when located on the breaker panel for example...

I use the word " filtering" in a metaphorical sense to describe my experience and impressions...Anyway nobody write anything I know of about that phenomenon...

I use the word "filtering" because no stones work in the same window nor in the same level...Be it an amethyst, agate, jasper,fluorite,tourmaline, jade, quartz, lava beads, malachite, shungite, etc, the list is too long to enumerate all the experiments I made with these different stones....

My system cost me 500 hundred dollars and the S.Q. exceed many way much costly system...

Audio is not about electronic engineering only, because a good piece of gear is equivalent to another good piece of gear, modulo some differences for sure; audio is mostly about the embeddings of any system, without which no system can sound at his peak potential possibilities...

Almost all audio forums are misleading and are about buying this or that, not about how to embed the audio components...If what you are is already good, and most of us owns already very decent apparatus, why upgrading like sheep without thinking about the question : how  to embed my audio system?
UPDATE:

I replace all  ordinary quartz sticks that shielded the tone controls of my Sansui amplifier with selenite quartz... The results were good with these but the results are better with selenite the sound is more natural with more weigh...

I order them because their format were more adequate but it seems they are better not only for a better fitting but for a better S.Q. also...
