  Just saw this!  Had to read thru couple pages of well...whatever.  Past 10k you really need to be careful as those are where the artifacts and slight imperfections in rig build start to show.
 
Not to throw shade on lesnumeriques' measurements - that's not my style, but for me their linear rise of 20 dB from 5k-10k seemed....immense, at the very least.  
 
Btw, here is my T1 isolated measurement.  Sorry if I'm not keeping up regularly with my posting, I'm overwhelmed as far as reviews/ moving across continents goes.  

 
 

 
Hey Ken, do you have a higher resolution image for this T1 measurement? The artifacting and quality of the image is making it harder for me to separate the frequency line, but if I could get a better quality image, I'd add the T1 to the chart. In-fact, if you have any others you want me to add, just let me know. I know it might not be fully accurate, but it might be a fun rough approximated point of comparison.

Getting real messy now lol, but I've updated to include @thatonenoob's T1 frequency measurement too.

The Sony of the R10/CD3000 era was a different beast, they were into pushing boundaries and this Sony seems to be recycling its 70mm driver. Let's hope I'm proven wrong.

Planning some listening later this afternoon...

I sold the CD3000 a while ago, would be interesting to see how the modern equivalent measures up.

I purchased serial number 1189 in October (At Launch) in Tokyo. I am wondering if Sony has a separate serial number scheme going on for different regions . Seems quite possible as it is hard to believe that 2 or 3 digits are just now showing up in US while the 4 digits units were available in Japan in October.

Easy to understand , the 2-3 digits were new, and people (technicians) would be flimsy or not doing stuff correctly. So they have less tolerances and skills in hand assembling it and quality controls. The rest of the market is genuine pig....Japan is getting 4 digits when technicians has been doing it so well, and nothing would result into a mistake...

Sonic comparisons aside, speaking purely aesthetics and build, the Z1R's look and feel a million times better lol. At least in my opinion.

 

[LaCuffia]

Mine is serial no. 132 and the Tokyo address is imprinted on the underside of headband - on the right hand side.

I wonder what the production number will be - 2,500, 5,000? Also, is it limited to 2016?

Another report I also want to impress on is that due to the closed off design, those very fine and microscopic trebles and lower and especially Upper trebles details (8-16khz bar as shown on wm1Z) in the Modern Pop genres are excellent in Z1R. I could also observe it from SA5000, but with a much louder volume out of the WM1Z, it is due to the openess design of SA5000 that I couldn't observe it well enough before. When I tried to use my palm to cover the back of the cups, I also hear it too. Therefore, the advantage of Closed of design from Z1R is showing here. If you are into modern genres or classic rock....and after burn-in. I think my Z1R has about 250 Hours or so...lol.

The Z1R keeps on getting better, and better.

That's been my impression too- really great detail retrieval. I also never heard a closed headphone sound so open. I guess the shape of the cup and resonance free housing technology paid off.

No address printed on mine either.

It may be that the Sony address is a requirement of the European CE mark. (Check above the address for the CE mark.)
Makes sense that it would only be on the units sold in Europe.

 

[thatonenoob]

My review unit had the address written on it.  I'm not sure if there are such geographical distinctions for these units though. 

 

[Whitigir]

CE means, it is Volume Capped mwuahahahaha!
