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...

As I said the photos in the freezer illustrates that freezing things is not entirely what it appears to be - realignment of atoms or whatever - there must be something else going on. At least that should be your conclusion if you got results with the photos in the freezer. The technique of using a home freezing can be improved by treating the freezer, the power cord and what is inside the freezer. AND what’s in the system and what’s in all the rooms! Again, it’s not something that can be explained in a few sentences or even paragraphs. Have you tried the photos in the freezer tweak or just heard about it?
Mahgister - I started first by crushing my own powders. It’s very much more difficult than I thought it would be. I’m sure you’ll be able to do it better than me, but if you plan to use a mallet be absolutely sure to wear protective goggles. Whichever way you do it, always use a face mask. There are health dangers in working with crushed stone, particularly quartz of any variety. Crushing your own stones can create extremely fine (sub-micron sized) and very sharp particles.
With one small bag of pre-crushed stone from Right Rocks, I could create 500 CrystalTops. I only need about 10 of them for my own system. For me it’s by far worth it to buy the stuff already crushed and sorted into regular sized sand or powder.
I also buy crushed stone from China at much cheaper prices, and they are very good. But they don’t have chrysocolla.
Ok  Geoff I think I understand even what you dont want to told me profusely....You are pointing the direction rightfully and I understand your point perfectly.... Thanks Geoff
