ACH has deep bass and characteristic firm treble, head room is very large.
In say Japanese, " Sukoshi Don Shari".
But, Mid sound is so natural.
So, I think, May be, Nova Driver is being good expression.
ACH Sound is so pleasant.
I just got my ach, and it was really amazing. The most impressive thing is the highs, the ceremic twetter really sounds like the electrostatic driver, and gives a very crysp highs with no irritating peaks. The mid and bass are also well balanced. This is definitely one of the best universal IEM in my collection! I can't believe that you sell it at such low price ! Anyway, it's incredible !
Pros: very nice sound. clear high freqs, detailed. subdued bass, but still clear and detailed.
Cons: A little bit heavy, so have to carefully choose ear tips for good fit (I have to make custom ear tips). No so good noise isolation. So with weight and isolation it s perfect for indoor usage but in crowd noisy places it's not so good.
ACH Ceramic Universal In-Ear Monitor
Great IEM, very airy and open. Very transparent and clear.
The new 3d printed shell fits very well and the sound is just entry level.
