They look weird more than anything else, but DAMN that sapphire cup is pretty.
I thought the Yamaha YH-5M was the unobtanium.
Which reminds me, there are still a few unknowns hanging around out there I can feel it deep in my bones. Someone has to find one.
M_S 8730 perhaps?... I think maybe Kabeer was the last chap to find that Ca_ton ( not named for safety reasons in searches ) I know there is one not yet found for sure ( not saying because of confidentiality agreement ) GET SEARCHING!
Dyna-x mang Dyna-x ultimaunobtainium, though one person in here has one :)
Here's my re-cabled HP-50A. I used the stock wires from the Left cup to the Right cup.
Kapton Gold looks nice with these headphones.
I damped with the stock open cell foam and a disk of 4 mm dense, soft wool felt. Sounds great.
Thanks nick n!
No screws. Snap tabs hold the baffle to the cup.
Stock open cell foam damping. That's it.
Left channel on left; Right channel on right. Stock Mono wiring.
Re-cabled for stereo with navships (ebay seller) using 26 AWG
Kapton insulated SPC multi-stranded wire - 4 wires are braided.
Thick (4mm) dense, soft wool felt damping over stock open
cell foam on the inside. It was a tight fit with the felt and
The Kapton wire is microphonic so I'll be looking for a soft
Pads are in great shape. They're secured with double-sided
tape cut from a large sheet. The tape seals the access
openings for the snap tabs.
Edit: I removed the dense felt and tried the configuration I used with a set of HP-1's. The sound quality improved quite a bit over the dense felt, alone. The stock open cell foam was too much with this configuration, though, so I cut it down and the sound remained over-damped. I removed the open cell foam and like what I hear. Pictures "show and tell."
Ring of Paxmate
Thin cotton disc.
nick n's secret sauce overlays Paxmate disc and cotton disc.
Stock open cell foam over-damped the sound.
Trimmed open cell foam disc over-damped the sound so I did not use it.
The back wave vents through the sides of the damping stack and out the un-damped cup slots.
THANKS for that i will have to give it a shot, that cotton must bring up the highs a fair bit then? What cotton is it?
Hmm ... late night modding hey. I know it all too well.
just threw mine on again to try and noticed they need a boost in the highs for sure.
YHD-1 to Fostex T10 Transplant
This modification sounds real good.
Too much slack in slider clamps. 2 layers of closed cell craft
foam serves as a friction brake so the cup rails remain in place.
Rubber cement keeps the closed cell foam in place.
Too much slack at the slider rails hinge was taken up with 3 cm
of Scotch tape.
Speaker grille cloth secured with double sided tape.
28 gage steel baffle is strong and light-weight.
Closed cell foam gaskets on both side of steel baffle.
Double sided tape exposed for securing pads.
Closed cell foam ear side gaskets and steel baffles.
Bushings/spacers have been installed on hinge and slider mechanism.
Adapters to seal the large cable entry opening in the T10 for
the YHD-1 smaller cable and strain relief. This is made with
2-mm hard plastic with a layer of closed cell foam. Without
these, there would be huge holes at the cable entry that
would function like big bass ports = Boomy Bass Bloat.
These were super glued inside the cups and over the T10
T10 stock pads are in pretty good shape.
Yamaha YHD-1 and Fostex T10 components ready for
Closed cell foam gasket over rear of steel baffle.
Hot glue holds and seals YHD-1 driver to baffle.
T10 yellow biscuit over foam in cup.
3, T10 cup-to-baffle screws.
Absolute best way to approach that ebay listing aspect is to notify whoever you think might be interested or whoever you speak with a fair bit about things, using the private message system.
We aways have to remember that things ( ANYTHING ) posted out in the open are also read by a huge massive number of people that have not signed up here A.K.A. "Joe Lunchpail General Public", or anyone instantly searching the web about a listing or for info without bothering to contribute or do much , if any, work.. Not only that but it possibly definitely drives up prices from sellers . I have noticed more than a few times where I was late getting back to a real deal only to find they relisted it at a way higher price or that is close to the current ripoff prices.
It's also why I often obscure names and model numbers in posts.
Much goes on behind the scenes here .
Something to keep in mind for the future.
Everyone benefits this way, and as takato said it doesn't screw anyone out of a deal they managed to find that went under the radar for whatever reason. The adrenaline rush with some search results stuff is a real thing at least here :)
BMF: what happened to the stock T-10 drivers in the YHD transplant i forget. You know you are hardcore when you are using a rare shell with other rare drivers instead :)
