Yes it is.
There is a crazy story behind this headphone. The guy who sold it, has got the AMT as a present at his marriage. He didn't know anything about headphones, didn't have an amp, only a TV. But he thought, that this strange things are not comfortable enough for watching TV. So he packed it back in the ovp and sold it many forgotten years later for 15.-€!

Mad jealous. Still need to find one of these... largest AMT driver ever put in a headphone despite being the second one ever produced.

AMTs can freak out a bit in the midrange, and theoretically that should get worse with more surface area... but even the smallest driver (ESS Mark 1) has tactility and raw speed that is something else to behold. This coming from a stat user...

what exactly did you mean by that?

Are the Sony MDR-7506 considered vintage yet? Can’t believe they came out more than 30 years ago lol!

By most widely accepted definitions...
20 years = vintage
100 years = antique

Nakamichi SP-7 and Grado SR60

Family resemblance is no coincidence. SP-7 uses a driver of similar origins and design as Grado HP-1000. Sounds like a vintage Grado! Plan to transplant driver to SR60.

Sansui SS-100

edit: to show Nak suspension strap.

It took me 11 years to find this one.

36mm ceramic titanium diaphragm
165g - super feather weight

This model has the Master designation, which I didn't know before I got it.


Colour coding!


Funky suspension design


Obviously soundstage is nothing special, just like all most-ear headphones.
Most other faculties are surprisingly good, bordering on the excellent.
Stock FR is the only weird part, but it takes tone correction shockingly well (I give it a health bass boost, and reduction in the mids).

Considering the driver size, the overall performance is great and among the better on-ear headphones I've heard.

Nothing new, but had two of my 3 favorite headphones out and took a picture: the SR-Xmk3 I bought from Japan, who have SR-5 white cable and sound different from all my other SR-X (they are mids cannons), who knows which driver they have inside; and the TDS-15 which for my tastes are the best out of all the vintage planars I have/tried. As an aside, I find the Russian orthos a marvel of simple engineering: they were probably designed to be assembled by an unskilled and disinterested labor force, and this makes them a modder's dream.

Spoiler: bonus: measurements on my flat plate rig with my L500, including the inevitable Lambda seal issues in bass

A very rare image!

D930 looks like some Sony headphones from that era

Pretty much a Sony OEM!

The AH-D930 desperately needs new pads though but the D900 is in excellent condition, both have drastically different sound signatures

Doing some repairs on the SRA-12S with a Lambda NB.

Amp started humming too much and I thought it may have been a ground loop so I rewired all my stuff but nope,


Opened it and found a loose board

Also youll notice one of the boards missing, that will be the phono amp board which Im still repairing

 

[Bingturong]

SRA-12S working perfectly now! Earrily quiet~

And I finally got a fuse for my SRA-8S, which proceeded to promptly blow the fuse on my transformer, meaning my Fostex which I use as a headphone amp and DAC can no longer work since its 100 V

Yay!
