ED9 > ED8 Blue > DT3 > ANV > CM9.      At first I thought the Blue and Red ED8 were different with the red having more upper midrange and treble but they are sounding very similar now with more break in on the red ed8. So far I'm just meh on the ATE; nothing wrong with it just not my preferred sound signature. It has the Audio technica sound profile which I generally like but the soundstage is lacking compared to the ANV and CM9,  IMO. I just love the tone and soundstage of the ED8 blue but the ED9 goes to the top for me because of its ability to place sounds in space and even create a sense of depth to music.

  How about soundstge of ED9 to ATE?

 
When the soundstage is large enough I did't pay much attention to it. 
 
Just a quick test using this video.  I feel that ATE is a bit larger.

-.- ......I WANT MY ATE NOW! -.-
 
Btw, this last ED9 brass nozzle combination works very good on GR also. Pretty good sounding IEM actually and no harsh/sibilance/sharpness in highs. But GR has different soundstage/imaging from other KZ`s, it`s like 

Λ-shaped soundstage (listener headspace midpoint in middle of that Λ "triangle" with face towards tip). I think GR would suit for those who like more intimate soundstage/imaging for old school rock for example.​

I believe that would be be the case since you mention B3's is obvious bigger than ED9. B3's cannot be bigger than 80 or m200, but ATE's just a little bit small than 80 or m200. So ATE's should be bigger than ED9. Thank you!

Sorry abou that.

I opened my ED9 right side backplate/grill (it is easy to remove and will go back easily and firmly). No change in sound. Basically...
 
* it is "fully open" design. That`s why it has so good soundstage and airiness.
  I can see through the driver when looked against light from one end when nozzle and backplate are removed.
 
* it is possible to change cable.
 
Will wait for my ATE first but I already see myself modifing these some day in future (cutting off my ANV modifying plans)

 
 
Actually this IEM build is strange... covering backplates wholly doesn`t seem to change sound also. I even did simple test and put tape over backplates leaving no gaps. Maybe... maybe bass got just a fraction tighter and less "boomy" but change is basically 0. Soundstage doesn`t seem to be affected at all.
So... whatever happens after the driver towards backplates doesn`t affect sound and can be modified, imo.
For example this would be nice and easy mod for those who want to make R/L look different, selfmade different backplates for example. Wooden ones would be very nice
 
Edit:
Oh! I forgot there`s a little hole by the side of cable entrance! That`s why there were basically no change in sound!
 
Edit:
Ok, second try - put tape over those holes also... I think bass and kicks got fraction tighter but difference again basically 0.
If someone else bothers to try, then feedback about it is welcome.

The ED9s sound just like the Piston 2 crossed with the Brainwavz Delta. Very impressive.

I don`t know what You mean by that because I haven`t heard BW-Delta but ED9 has less bass and better well balanced sound (not flat but pleasantly V-shaped with good mids) compared to Piston2.1. And of course soundstage is better. Little more out of headspace presentation also.
 
Edit: 
 
I really recommend to play with filter material + brass nozzles if ED9 sounds littlebit sharp in highs.
I think I just found better combination than previous. Because putting gold nozzle foams into brass ones showed good result, I gave a try with Piston2 filter foams from my broken pair and it sounds great - sharpness in highs is gone and bass microdetails still present.

I took some photos of filters that can be used with KZ-ED9. Feel free to use them if you want to.
 
KZ-GR black filter:  Boost bass
 

 
KZ-GR red filter: make it more balance sound
 

 
KZ-ED9 shiny filter: V-shape sound
 

 
KZ-ED9 brass filter: more balance sound

ilikeiem, have You already tried brass filters with gold nozzle foams or other foam material? If not, then definitely recommend it! Make sure You push foam down against nozzle grill 
Atm, I really like what I`m hearing out of my ED9 with brass nozzles + Piston2 foams. With this setting ED9 is new budget-king for me.
 
Btw, GR filters winding part is littlebit longer and different than ED9 nozzles. I can use them but not much improvement compared to gold nozzles without foam and grill or brass with golden foams.

Thanks for your suggestion man. I will try that.

I’m curious what's inside KZ-ED9. So I try to open it from the back.   Cable will be easily changed. 
 

 

[CoiL]

So, what cable are You going to use? 

 I haven`t decided yet. Want something cool 

 
About "easily changed" I think re-soldering leads will be not so easy and requires proper soldering-iron tip to get close to soldering points.

Somewhat harsh treble that bothered me earlier has subsided to a great extent now. ATM, I can safely say ED9 with shiny filters and JVC spiral dots tips (large) provides me the best listening experience of all the IEMs that I have (on any source). Listening to Mogwai was never this good for me as it is now with ED9

How long did it take to "burn-in" and get rid of that harsh treble?

KZ ED9 - Blue Mod​

 

​

 
I've been messing around with these all week, trying different filter materials (various cloths and papers) and tips to optimize my enjoyment of the brass filters. This is what sounds best to my ears.
 
The blue foam used is very similar to that in the Gold filters, but with smaller pores. The image is pretty poor, but enlarged you should see that it is compressed so it sits just below the filter paper. The filter paper is also slightly pulled back so the vent is now fully open. I find this maintains everything that is so great about the brass filter; soundstage, detail, imaging. In addition, it brings the bass back. It's not as omnipresent as it is in the Gold filters, but quick, punchy, and complimentary to everything else.
 
The large blue tips that came with the Huawai Honor are perfect with these. The extra tip length seems to help with making the ED9 sound even more spacious. For my ears they also seal very well, and require no fidgeting.
 
Some of my Favorite Test Tracks:
 
Supertramp - Rudy
Adam Freeland - Heel and Toe (Evil Nine Remix)
Daft Punk - Touch
Gorillaz - Empire Ants (ft. Little Dragon)
King Crimson - Starless and Bible Black
 
While I still love the Micro Ring and ANV, I can't deny that the ED9 is on another level, and a very impressive iem for it's class.
