They do. They appear in the SFI orthos, the Eagle, and the ATH-2 with clones. Maybe I even forgot some ortho now.
eagle are the most efficient SFI's base ortho (better than ATH-1, ATH-2/VSH5/Sansui SS L-55 or Pro30), it's about 8 or 16ohm...

I'm not so sure about the systematics, but I think I solved the problem of "no ball" and "cheap sound" I mourned about. The solution has a simple name:
AKG K141 velours pads.
I glued them onto the stock pads by means of doublesided tape. That solved most of the things I had disliked, now the sound is warmer, airier and more relaxed, but I still enjoy its great speed factor. They are also much nicer to wear now. I prefer them to the HP2 right now and would put them into the same leage as my beloved T20v2 - at least in respect of my listening habits. The Fostex still has the edge in respect of mids presentation and sound "weight" (K271 sort), but the SS-L55 sounds more dynamical and has a more alive presence (Grado sort).
As I was at it, and as I have fallen in love with their 80's looks anyway, I granted them an old MS2 cable and T5P headband pads.
nice mod nickchen...
edit:
you should try this K141 velour pads on you NAD, keep the stock spiral chords...
it's better than replace em with Grado cable for example, they just dont have good sinergy based on my experiment...

I shot a
NAD RP18 , propably almost NOS, at german ebay yesterday.
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=300528186537&ssPageName=STRK:MEWNX:IT For some reasons, that action was with a "no shipping abroad" passus, nevertheless the seller told me afterwards that he got flooded with inquiries from Indonesia and Poland to sell this thing offside the usual ebay routines, my luck that he didn't. My Ninjas said the final price of 208€ was reasonable. But after 4 vintage orthos in 3 months, my abandoned
saves-for-LCD2-funds are completely spent now...
To say that I am thrilled is somewhat an understatement. I am
so proud to possess one of the famous T50v1 clones soon. Heartly thanks to Whitney and Brian for their advice and encouraging!
ahahahaaaaa, so you're the one who won that NAD from ebay.de...
nice find, hopefully they came in a good shape...
yes, a lot of my friend on local forum contact the seller too often...
you had stepped a head from all my friend here, since the seller always respond dont deliver abroad... lol
if you need any advice for damping, just ask...i'll share with you everything i know to tweak this bass monster...

Mylar NADs? Are there different versions of the RP18? However, I've already started some investigations of sources & prices for W11 or O2 pads in case my pad bestiary doesn't contain something suitable.
@Rick: That is much better, I told you, just one short question would be to little to attract the attention of the ninjas...

Two kinds of driver have been reported on NADs:
1) Kapton driver - These are bass heavy & reportedly have highly rolled treble.
2) Mylar Driver : Great balance even stock, rolled off only slightly at both ends. Nearly perfectly damped stock.
i have own the basslight a.k.a mylar one before, now mine are the bassheavy/kapton one...
first impression, i like the bassheavy more than the basslight one...
soundwise, really similar to T50v0 in stock form..but darker, more bassy but faster...

No, that one hasn't been opened up yet. Didn't want to mess the baffle seal.
The pics are courtesy Kabeer.
i had replace the blutak sealing on the baffle with foss auto sealer (silicon gasket'er for car engine)...
bring up the bass much more than blutak, try it...
dont worry, i use this methode on the basslight (my friend own it now) & my bassheavy NAD...

The Once And Future Headphone.
The Headphone They Don't Want You To Hear.
The Headphone Technology That Got Away. Yep, I like that one. I hereby nominate yours as the Ortho thread's official catchphrase.
Oh yes. Just as gurubhai and Kabeer say. Remember, Foster Radio, aka Fostex, is possibly the demon OEM of Japan. They'll make anything, any way, for anybody. We should be surprised that there are only 2 known variants and should be keeping a ninja-eye out for the third.
When I first posted about the 1978 North American market T50 back in 2004, little did I know that I'd be opening the biggest can of headphone worms evar. Fostex peppered the world with so many variations on this theme, it makes you wonder what possessed them to attempt to establish this headphone in the market, any market. We can only assume they were proud of what they'd accomplished. The T50 was a marketing failure, but the HE-5/6 and LCD-2 are vindications of the basic design.
It's only my guess, but I believe the Mylar NAD was primarily for the German market, so you may be in luck. Fingers crossed.
That's a good question. My first guess would have something to do with the placement of the natural resonant frequency of the diaphragm, giving the midrange a smooth bump in the "warmth" region, but I could be all wet. The thing to do would be to analyze your reaction to find exactly what about the Yama midrange appeals to you and what it is the other headphones lack.
Power handling specs are more art than science, but if the goal is to keep diaphragm failures to a minimum, increasing the sensitivity couldn't hurt. Then at least the headphones will be playing too loud for comfort when they reach their thermal danger zone.
And I say good luck to anyone embarking on the rough waters of the headphone market with a new orthodynamic.

Im putting my bet in now that these are Kapton

.
And wualta I cant remember for 100% certain but I think both my Kapton and Mylar pairs came from Germany.
yup, it's definetely are a bassheavy...from the look of the spiral chords...
my bassheavy NAD use the same as those, my ex basslight use different vinyl straight cables...
cmiiw...
