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...

Thanks for asking. I was one of the very first in the country, probably the world, to experiment extensively with both deep cryo and home deep freeze for all manner of audio stuff, from cables to CDs to LPs to CD players, hardware for my Sub Hertz Nimbus isolator,  and beyond. That was more than twenty years ago. Now cryo labs are a cottage industry.
How 24 hours deep freeze in my fridge compare to cryogenic freezing? Is the effect of this freezing longtime or shortime effect?
All thermodynamic processes are irreversible. Home freezer technique 48 hrs is say, 75-80 % of deep cryo. However - and this part is very hush hush 🤫 - the home freezer technique involves Morphic resonance at some level so, once you get into it, and learn the tricks of the trade, the home freezer technique - even though there is such a large temperature difference between -10 degrees F and -300 degrees F - can be made very powerful, more powerful than deep cryo IMHO. It’s a lot like alchemy. 😬

How normal freezing can be more powerful than deep cryo? what do you make for that? 
 I am interested for sure...
Unfortunately the explanation is beyond scope of this discussion. Even if it wasn’t it’s a very long story. It’s not easy to explain, either.  But the key is that cryogenic and home freezing processes involve Morphic resonance in addition to straightforward physical science. This idea of information fields and low temperatures is perhaps best demonstrated by the notorious Photos in the Freezer Tweak. Of course, the idea that the home freezer can be made more powerful than -300 deep cryo is blasphemy to every audiophile who thinks all tweaks are snake oil and believes “sound engineering principles” are the golden path to audio Nirvana.
