It seems that the more you take the baffle and cup out of the way, the more neutral they sound. Given how fast Sennheiser introduced the 2002 model (with a modified cup) after the 2000, it's probably not a bad guess to make that the cup design on the 2000 wasn't even close to optimal, or even decent.

Curiously, bass extension didn't suffer when the cup was taken off. Doesn't start dipping until about 35 Hz. Treble isn't as harsh as before, but I attached a foam disc directly to the back of the driver - might have something to do with it. Soundstage is a bit more open, no surprise there.

Care to divulge what your avatar is a picture of? Looks pretty.

Thats a car audio ortho tweeter from some local Kiev company. Basically same people, who made that Amfiton 25.

As for the name, I suggest hyphenating the heck out of it: CrossTex-FosFade, or even CrossTex-FosFade: The Headphone.

Ahahah, thats cuute

Hm, never thought all other orthos was corrugated, nice

1. Earliest version, non-corrugated diaphragm, driver parts hold together by screws. Metallic protective plate at the back is placed along the magnets

2. Non-corrugated diaphragm, driver parts hold together by clips. Metallic protective plate at the back is placed across the magnets (for better sound, need to rotate it)

3. Same as #2, but with corrugated diaphragm

4. Something in-between 2 and 3 (half-corrugated). Possibly a defect.

 

Corrugated diaphragm have a bit more bass, but non-corrugated seems to provide flatter response and better micro-details. Variant #4 is something in-between the two.

This is very interesting. Is it possible to tell from the outside of a TDS-15 what version of the driver it has inside?

For instance, this one?

The prints of the name might play a big role in it. See mines for example (excuse me for the messy desk, as usual):

The one on the left has no symbols at all around amfiton (I'm assuming that's what the word there is).

The right one has a circle on both sides of amfiton.

Yours has one marking to the left of amfiton.

Though curiously, Drakkard, had there ever been any record of TDS-15's with the headband on the left? or should we assume it was someone's DIY job? (I replaced the earpads and cables)

Kalbee pretty sure I have the exact same two models as you do ( but both same headband as the grey ones ) . Would love to hear what comes of this.

Thanks for posting the pics I was too busy tonight to get mine posted

Mine has C C C P written with very small type inside the small symbol.

(I have filled in the white paint myself to make it all more visible.)

That's definitely a diy.
Note new ear cushions too.

As far as I know - no. They was made on two factories, but that does not reflects on driver construction.

Interesting, I wonder how the person managed to fix the cups on the headband.

I was the one that put that ear cushion and new cable (not really shown in picture), but the headband was like this when I received it.

Thanks for the picture link ;)

Ah I see. Nice ear cushions =)

$2000 for a beat-up YH-1000 with a faulty driver? I guess.

oh the YH-1000 dropped in price then

I wonder if there is corrosion on the driver traces in this one.

Kalbee i would be curious to see their attachment method for the aftermarket headband whenever you get around to it.

Drakkard, how does ТДС-7 Амфитон and ЭХО Н-16 compare to TDS-15

I did not listen to TDS-16. People report they are aggressive, but not bright. Good and fast upper bass, but lacking part of middle and low. That makes them good for Metal - guitars and such.

TDS-7 is good with macrodynamics, sort of big sound with somewhat deep (but not wide) sound stage. It have thick diaphragm, I believe it is the reason for this sound signature. Also, this is the most uncomfortable headphones in the universe =)

TDS-15 seems best both of them in details retrieval, instrument separation, and sense of air, but lacking bass in stock form.
