Looks like S12 is going to be a runner up on your top chifi list

I have ACME 8 and your impressions on it not what i can hear from mine, the bass on Acme 8 what i love about it ( i use to have IMR R1 and the bass on those are great ) the mids are not recessed at all, you probably didn't get a good seal on those, i use large foam tips.

For those looking for alternative from ie match>>https://penonaudio.com/accessories/3.5mm-impedance-adapter.html Its in 3.5 single ended though not balance.

Everyone's ears are different, i use large size spiral dot and i get perfect seal even when my jaw is open or closed there is no change in the seal and sound.

I use large spiral dot, perfect seal on my ear:smile_phones:

Don't have comply 500 but i do have Symbio W and can confirm outer bore is wider and narrower on spiral dot which is why judging from the Acme 8 design spiral dot is good choice to use as tips.

Try spiral dot as tips on your Acme 8, looking at the design it should improve sound, spiral dot bore is wider than other wide bore tips

Saw a review @ taobao on s12, its translated from chinese.

You can ask the seller from aliexpress to declare value lower than actual price to avoid custom fees

Is your order with you already? invoice is most likely for customs declaration only, if you have s6 with you already then no need to pay anything else.

Yeah this replacement is ok its in phase both sides, just to double check the right unit on the 2 pin socket side the red wire should be on the bottom the pictures a bit blurred cant see clearly. if red wire is on bottom then your all good

right side is out of phase and soldered wrong on the driver side, show this picture to Bob @ IMR he will send you replacement.

On people who received there zenith's do you guys notice harshness on your units?? everything is better than my R1 except its quite fatiguing to listen to, i keep going back to my R1, any suggestions?

ACME8 cost 1045$ for universal version & 1194 $ for custom if you buy directly from there store in taobao

Yeah those are wave guides supposedly make the bass go deep

Yeah you need to create account, after you create account you should set your address first in account settings so can purchase easily, yeah i tried just now buy now don't work for some reason,scroll down until you see add cart option then add

Here is the link you can order from them directly its cheaper>https://item.taobao.com/item.htm?_u=b3na57or3ae3&id=550126278912 Its in chinese though so use chrome as browser to translate, i send them a message they do shipped internationally , Taobao is like a black hole too much shiny things

I think its ACME8 they designed is to have same bass as a dynamic driver.

Try sending him message on IMR facebook page>>https://www.facebook.com/imracoustics/ , he replies on all my messages there

Anyone here had the chance to try ACME8??

Haven't heard it yet like you I'm waiting for sound impressions from other people, HBB should be posting his review on S10 soon, he also favor S8F compare to S10.
